Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION NOTICE

Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.
Indicates a situation that could result in equipment or property-damage only accidents.

Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:
· Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/ sleeves, butyl gloves, safety glasses, hard hat/ bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
· When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
· If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit.

7

A2L Information

adequate temporary solution shall be used. This shall be reported to the owner of the equipment, so all parties are advised.
Initial safety checks shall include:
· Cabling is not subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other adverse environmental effects. Account for the effects of aging or continual vibration from sources such as compressors or fans.
· Capacitors are discharged. This shall be done in a safe manner to avoid possibility of sparking.
· No live electrical components and wiring are exposed while charging, recovering, or purging the system.
· Verify continuity of earth bonding.
· Replace electrical components with Trane replacement parts, or those meeting the same ratings and qualified for flame arrest protection, UL LZGH2 category.
Leak Detection
Never use an open flame to detect leaks. A halide torch should not be used. Use only approved leak detection methods per this instruction manual.
The following leak detection methods are deemed acceptable for all refrigerant systems.
Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, the sensitivity may not be adequate, or may need recalibration. (Detection equipment shall be calibrated in a refrigerant- free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL gas (25% maximum) is confirmed.
Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
Examples of leak detection fluids are:
· Bubble method
· Fluorescent method agents
If a leak is suspected, all naked flames shall be removed/ extinguished.
If a refrigerant leak is found which requires brazing, all refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak.
Refrigerant Removal and Evacuation
When breaking into the refrigerant circuit to make repairs ­ or for any other purpose ­ conventional procedures shall be used. However, for flammable refrigerants it is important that best practice be followed, since flammability is a consideration.
The following procedure shall be adhered to:
8

1. Safely remove refrigerant following local and national regulations.
2. Evacuate.
3. Purge the circuit with inert gas.
4. Evacuate (optional for A2L).
5. Continuously flush or purge with inert gas when using flame to open circuit.
6. Open the circuit.
Prior to refrigerant removal, open all appropriate valves, including solenoid and electronic expansion valves (EXVs). Use control settings, where available. When not available, manually open all electronically controlled valves using acceptable service procedures.
The recovery equipment shall be in good working order with instructions available. Equipment shall be suitable for the recovery of the flammable refrigerant. For specific handling concerns, contact the manufacturer. Ensure all hose connections are checked for tightness to avoid refrigerant leaks.
The refrigerant shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. Do not mix refrigerants in recovery unit and especially not in cylinders.
Refrigerant recovery unit should be purged with an inert gas after each use or before using with a different refrigerant Class ­ for example, A2L to A1.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The compressor body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out safely.
The system shall be purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems.
The system shall be vented down to atmospheric pressure to enable work to take place.
The outlet for the vacuum pump shall not be close to any potential ignition sources, and ventilation shall be available.
Refrigerant Charging
In addition to conventional charging procedures, the following requirements shall be followed.
· Ensure that contamination of different refrigerants does not occur when using charging equipment.
· Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
· Cylinders shall be kept in an appropriate position according to the instructions.
SS-SVX014A-EN

A2L Information

· Ensure that the refrigerating system is earthed prior to charging the system with refrigerant.
· Label the system when charging is complete (if not already).
· Extreme care shall be taken not to overfill the refrigerating system.
Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leaktested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
Prior to refrigerant charging, open all appropriate valves, including solenoid and electronic expansion valves (EXVs). Use control settings, where available. When not available, manually open all electronically controlled valves using acceptable service procedures.
Decommissioning
Before carrying out the decommissioning procedure, it is essential that the trained service personnel is completely familiar with the equipment and all its details. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is essential that electrical power is available before the task is commenced.
1. Become familiar with the equipment and its operation.
2. Isolate system electrically.
3. Before attempting the procedure, ensure that:
a. Mechanical handling equipment is available, if required, for handling refrigerant cylinders.
b. All personal protective equipment is available and being used correctly.
c. The recovery process is supervised at all times by a competent person.
d. Recovery equipment and cylinders conform to the appropriate standards.
4. Pump down refrigerant system, if possible.
5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
6. Make sure that cylinder is situated on the scales before recovery takes place.
7. Start the recovery machine and operate in accordance with instructions.
8. Do not overfill cylinders (no more than 80% volume liquid charge).
9. Do not exceed the maximum working pressure of the cylinder, even temporarily.
10. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and
SS-SVX014A-EN

the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
11. Recovered refrigerant shall not be charged into another refrigerating system unless it has been cleaned and checked.
12. When equipment has been decommissioned, attach a signed label which includes the date of decommissioning.
A2L Application Considerations
This product is listed to UL standard 60335-2-40, Household and Similar Electrical Appliances ­ Safety ­ Part 2-40: Particular Requirements for Electrical Heat Pumps, Air-Conditioners and Dehumidifiers, which defines safe design and use strategies for equipment using A2L refrigerants. This standard limits the refrigerant concentration in a space in the event of a refrigerant leak. To meet the requirements, the UL standard defines minimum room area, refrigerant charge limit, minimum circulation airflow and/or ventilation airflow requirements, and limits the use of ignition sources in spaces. The standard may require a unit refrigerant leak detection system.
For equipment with R-454B and charge amounts less than or equal to 3.91 lbs per circuit, this UL standard does not prescribe a room area limit and does not require a refrigerant leak detection system or any circulation airflow or ventilation airflow mitigation strategies. However, ignition sources in ductwork must be evaluated.
Depending on the application, a specific requirement of ANSI/ASHRAE Standard 15, Safety Standard for Refrigeration Systems, could be more stringent than UL 60335-2-40 requirements. See Refrigeration Systems and Machinery Rooms Application Considerations for Compliance with ASHRAE® Standard 15-2022 Application Engineering Manual (APP-APM001*-EN) for more information.
Ignition Sources in Ductwork
Do not install open flames in the ductwork. Hot surfaces exceeding 700°C (1290°F) should not be installed in the ductwork unless the average airflow velocity is not less than 1.0 ms (200 ftmin) across the heater and proof of airflow is verified before system is energized.
Electric heaters can exceed the surface temperature limit if airflow distribution is poor, or insufficient airflow is provided over the heater.
Surface temperatures of most gas heaters do not exceed the surface temperature limits due to ANSI construction requirements.
Ignition Sources in Unit
This UL-listed unit does not contain any ignition sources. All potential ignition sources, (including factory or field installed accessory electric heaters, gas heaters, relays, and contactors) were evaluated during product UL listing.

A2L Information

Minimum Room Area Limits (Refrigerant charge greater than 3.91 lb per circuit)
Equipment with R­454B charge amounts greater than 3.91 lb per circuit may require additional circulation or ventilation airflow mitigation strategies. In this case, there are two minimum room area (Amin) thresholds.
· The first threshold defines when equipment serving a single room is required to provide circulation airflow, either continuous or activated by a leak detection system. A ducted system requires circulation airflow unless the smallest room it serves is larger than the adjusted Amin threshold. This product contains a leak detection system if a circuit charge is greater than 3.91 lbs. As a result, no further leak detection system evaluation is needed.

· The second threshold defines when additional ventilation airflow is required. If the room area, A or TA, is below the adjusted Amin or TAmin threshold, additional ventilation is required to remove refrigerant in the event of a leak. Refer to UL 60335-2-40 Clause GG.8 and ANSIASHRAE Standard 15 Section 7 for natural and mechanical ventilation requirements. See equipment nameplate and table below for minimum room area.
Split systems minimum room area requirements need to be determined after final field charging. Use the following figures and the largest final circuit charge to determine the systems Amin value. Record the final charge value on the label provided on the condensing unit.

Release height is the vertical distance from the floor to the lowest point in a space refrigerant would leak from first. The minimum value is 0.6 m from the floor. This point is typically the bottom of free return openings or supply diffusers. For fully ducted units, the release height is 2.2 meters.

Minimum Room Area (Amin) Adjustments
Use equation below to adjust the minimum room area, as applicable, based on the unit’s installation height, altitude, and occupancy level it serves.

In addition, Amin can be adjusted if the unit is installed in a room at a height that is higher than the minimum height shown on the unit. To adjust Amin, multiply by the ratio of the unit minimum release height (in meters) / actual release height (in meters). Use 0.6 m in the ratio for unit minimum installation heights less than or equal to 0.6 m.
For institutional occupancies, ASHRAE Standard 15 applies an additional adjustment factor Focc to the amount of a charge allowed in a space. To calculate the adjusted
SS-SVX014A-EN

Amin for institutional occupancies, multiply the Amin on the nameplate by two. EXAMPLE 1: 20 Ton Packaged Rooftop Multi-Zone VAV System Serving an Institutional Occupancy Space The packaged unit serves 7600 ft2 of a nursing home located at an attitude of 4000 ft. The unit has two equally charged 10 ton refrigeration circuits. Each circuit has 12 lbs

A2L Information

of refrigerant with a minimum room area requirement of 180 ft2 with a 2.2 m release height.
TAmin.adj = 180 ft2 x 1.05 x 2 = 378 ft2
No additional ventilation is required.
EXAMPLE 2: 10 Ton Split System Serving a Single Commercial Occupancy Space
The split system serves a 1500 ft2 manufacturing space at 5000 ft altitude. The final installed charge of the single circuit 10 ton unit is 20 lb. The unit has an open return with a release height of 1 m and ducted supply air. The unit Amin is 660 ft2.
Amin.adj = 660 ft2 x 1.11 = 733 ft2
No additional ventilation is required.
Determining Room Area (A or TA)
The room area (A) is the room area enclosed by the projection to the floor of the walls, partitions, and doors of the space that the equipment serves. For ducted systems, total room area (TA) of all rooms connected by ducts, may be used instead of A.
Rooms connected by drop ceilings only are not considered a single room.
Rooms on the same floor of the building, and connected by an open passageway, can be considered part of the same room if the passageway is a permanent opening, extends to the floor and is intended for people to walk through.
Adjacent rooms on the same floor of the building and connected by permanent openings in the walls and/or doors between rooms (including gaps between the wall and the floor), can be considered part of the same room if the openings meet the following criteria.
· The opening is permanent and cannot be closed.
· Openings extending to the floor, such as door gaps, need to be at least 20 mm above the floor covering surface.
· Natural ventilations opening areas must meet the requirements of ANSIASHRAE Standard 15-2022, Section 7.2.3.2.
Rooms that are connected by a mechanical ventilation system can be considered a single room area if the

mechanical ventilation system meets the requirements of ANSIASHRAE Standard 15-2022, Section 7.6.4.
Leak Detection System (Refrigerant charge greater than 3.91 lb per circuit)
The leak detection system consists of one or more refrigerant detection sensors. When the system detects a leak, the following mitigation actions will be initiated until refrigerant has not been detected for at least 5 minutes:
· Energize the supply fan(s) to deliver a required minimum amount of circulation airflow.
· Disable compressor operation.
· Provide an output signal to fully open all zoning dampers, such as VAV boxes.
· Provide an output to energize additional mechanical ventilation (if needed).
· Units without airflow proving will disable electric heat sources.
Building fire and smoke systems may override this function.
If the refrigerant sensor has a fault, is at the end of its life, or is disconnected, the unit will initiate the mitigation actions. Mitigation actions may be verified by disconnecting the sensor.
The refrigerant sensors do not need service. Use only manufacturer-approved sensors when replacement is required.
Field Piping Installation and Charging
When refrigerant piping is routed indoors, protect from physical damage in operation or service, and verify installation complies with national and local codes. All joints must be accessible for inspection prior to being covered.
Follow the Refrigerant Charging procedure. Prior to refrigerant charging, check field-made indoor joints for leaks using an instrument with a sensitivity of 5 grams per year refrigerant. Pressurize the system to 25% of the maximum allowable pressure. Verify no leaks are detected.

Pre-Installation
Unit Inspection
Inspect material carefully for any shipping damage. If damaged, it must be reported to, and claims made against the transportation company. Compare the information that appears on the unit nameplate with ordering and submittal data to ensure the proper unit was shipped. Available power supply must be compatible with electrical characteristics specified on component nameplates. Replace damaged parts with authorized parts only. Important: Units ordered with a VFD cannot be field
converted to 460 V from 208-230 or from 208230 V to 460 V.
Inspection Checklist
To protect against loss due to damage incurred in transit, complete the following checklist upon receipt of the unit. Inspect individual pieces of the shipment before
accepting the unit. Check for obvious damage to the unit or packing material. Inspect the unit for concealed damage before it is stored and as soon as possible after delivery. Concealed damage must be reported within 15 days. If concealed damage is discovered, stop unpacking the shipment. Do not remove damaged material from the receiving location. Take photos of the damage if possible. The owner must provide reasonable evidence that the damage did not occur after delivery. Notify the carrier’s terminal of damage immediately by phone and by mail. Request an immediate joint inspection of the damage by the carrier and the consignee. Notify the sales representative and arrange for repair. Do not repair the unit until the damage is inspected by the carrier’s representative.
Testing for Leaks
All units are shipped with a holding charge of nitrogen in each circuit and should be leak tested before installation. 1. Remove the access panel. 2. Locate the liquid line or suction line access valve for
each circuit. 3. Install gauges to determine if the circuits are still
pressurized. If not, the charge has escaped and should be repaired as required to obtain a leak-free circuit.
SS-SVX014A-EN

Lifting Recommendations
WARNING
Improper Unit Lift!
Failure to properly lift unit in a LEVEL position could result in unit dropping and possibly crushing operator/technician which could result in death or serious injury, and equipment or property-only damage. Test lift unit approximately 24 inches (61 cm) to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level.
NOTICE
Equipment Damage!
Use spreader bars to prevent straps from damaging the unit. Install the bars between lifting straps, both underneath the unit and above the unit to prevent the straps from crushing the unit cabinet or damaging the finish.
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly distributed. See “Weights,” p. 24 for approximate unit weights.
The crated unit can be moved using a forklift of suitable capacity. For lifting the unit, attach lifting straps or slings securely to the lifting holes at each corner (see unit drawings in “Weights,” p. 24). Use spreader bars to protect the unit casing from damage. Test lift the unit to determine proper balance and stability.
Clearances
Provide enough space around the unit to allow unrestricted access to all service points. Refer to the “Dimensional Data,” p. 15 for unit dimensions and minimum required service and free air clearances. Observe the following points to ensure proper unit operation.
1. Do not install the unit under a low overhang. Condenser discharge must not be restricted, refer to notes in “Dimensional Data,” p. 15. Important: Do not obstruct condenser discharge air. This can result in warm air recirculation through the coil.
2. Do not locate the unit in a position where runoff water, or falling snow from roof, can fall into the fan discharge openings.
3. Condenser intake air is supplied from three or four sides of the unit. Adhere to the minimum required clearances given in unit dimensional drawings (see “Dimensional Data,” p. 15).

Refrigerant Piping Procedures (Outdoor Units)
WARNING
R-454B Flammable A2L Refrigerant!
Failure to use proper equipment or components as described below could result in equipment failure, and possibly fire, which could result in death, serious injury, or equipment damage. The equipment described in this manual uses R-454B refrigerant which is flammable (A2L). Use ONLY R454B rated service equipment and components. For specific handling concerns with R-454B, contact your local representative.
WARNING
Refrigerant under High Pressure!
Failure to follow instructions below could result in an explosion which could result in death or serious injury or equipment damage. System contains refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.
WARNING
Explosion Hazard!
Failure to follow instructions below could result in an explosion which could result in death or serious injury, and equipment damage. NEVER bypass system safeties in order to pump down the unit component’s refrigerant into the microchannel heat exchanger (MCHE) coil. Do NOT depress the compressor contactor since it effectively bypasses the high-pressure control.
Each unit ships with a holding charge of dry nitrogen. The nitrogen should be removed and the entire system evacuated (at the proper time) to avoid possible contamination.
1. Remove the compressor service access panel.
2. Locate the liquid and suction line access valves. Check that the piping connection stubs (see Figure 17, p. 26) line up properly with the holes in the unit cabinet.

Figure 17. Outdoor units – refrigerant piping (with dry nitrogen)
Red Tag
Manifold Gauges
Gas Line Gauge Port Liquid Line Gauge Port 3. Install gauges to determine if the circuits are still pressurized. If not, the charge has escaped and should be repaired as required to obtain a leak-free circuit. If the circuits are still pressurized, use the gauges to slowly release the nitrogen charge to the atmosphere and remove both seal caps from the outdoor unit connection stubs.
NOTICE
System Component Damage!
Do not remove the seal caps from refrigerant connections until prepared to braze refrigerant lines to the connections. Excessive exposure to atmosphere (> 5 min.) may allow moisture or dirt to contaminate the system, damaging valve seals and causing ice formation in system components.

26

SS-SVX014A-EN

Installation

WARNING
Explosion Hazard and Deadly Gases!
Failure to follow all proper safe refrigerant handling practices could result in death or serious injury. Never solder, braze or weld on refrigerant lines or any unit components that are above atmospheric pressure or where refrigerant may be present. Always remove refrigerant by following the guidelines established by the EPA Federal Clean Air Act or other state or local codes as appropriate. After refrigerant removal, use dry nitrogen to bring system back to atmospheric pressure before opening system for repairs. Mixtures of refrigerants and air under pressure may become combustible in the presence of an ignition source leading to an explosion. Excessive heat from soldering, brazing or welding with refrigerant vapors present can form highly toxic gases and extremely corrosive acids.
4. Cut, fit and braze tubing, starting at the outdoor unit and work toward the indoor unit. See “Charging Levels,” p. 30.
Note: Use long radius ells for all 90° bends.
All brazing should be done using a 2 to 3 psig dry nitrogen purge flowing through the pipe being brazed, see Figure 17, p. 26.
NOTICE
System Component Damage!
Install a regulating valve between the nitrogen source and the gauge manifold. Unregulated pressure can damage system components.
NOTICE
System Component Damage!
Wet-wrap all valves and protect painted surfaces from excessive heat. Heat can damage system components and the unit finish.
5. Shut off nitrogen supply. Shut off the manifold valve for the line that is connected to the suction line access valve. Disconnect the line from the access valve.
6. Reinstall the red tags, if they are removed during brazing.

Refrigerant Piping Procedures (Indoor Unit)
Once liquid and suction lines are complete to the refrigerant connections on the indoor unit, remove the gauge port core(s) on the indoor unit connection stubs to release the dry nitrogen charge.
NOTICE
Unit Damage!
Do not apply heat to remove seal caps until the gauge port cores have been removed. If seal caps are intact, application of heat may generate excessive pressure in the unit and result in damage to the coil or expansion valve.
1. Remove both seal caps from the indoor unit connection stubs.
NOTICE
Unit Damage!
Failure to follow instructions below could result in damaging the unit. Do not remove the seal caps from refrigerant connections until prepared to braze refrigerant lines to the connections. Due to the high hygroscopic properties of the POE oil, excessive exposure to atmosphere will allow moisture to contaminate the system, damaging the compressor.
2. Turn on nitrogen supply. Nitrogen enters through the liquid line gauge port.
3. Braze the liquid line connections.
4. Open the gauge port on the suction line and then braze the suction line to the connection stub. Nitrogen will bleed out the open gauge port on the suction line.
5. Shut-off nitrogen supply.
6. Reinstall the red tags, if they are removed during brazing.

Leak Check
WARNING
Explosion Hazard!
Failure to follow these instructions could result in death or serious injury or equipment or property-only damage. Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene, oxygen or compressed air or mixtures containing them for pressure testing. Do not use hydrogen mixtures containing refrigerant and air above atmospheric pressure for pressure testing as they may become flammable and could result in an explosion. Refrigerant, when used as a trace gas should only be mixed with dry nitrogen for pressurizing units.
WARNING
Explosion Hazard!
Failure to follow safe leak test procedures below could result in death or serious injury or equipment or property-only-damage. Never use an open flame to detect gas leaks. Use a leak test solution for leak testing.
After the brazing operation of refrigerant lines to both the outdoor and indoor unit is completed, the field brazed connections must be checked for leaks. Pressurize the system through the gauge port with dry nitrogen to 200 psi. Use soap bubbles or other leak-checking methods listed under A2L Work Procedures section to ensure that all field joints are leak free. If not, release pressure, repair and repeat leak test.

System Evacuation
1. After completion of leak check, evacuate the system.
2. Attach appropriate hoses from manifold gauge to gas and liquid line pressure taps. Note: Unnecessary switching of hoses can be avoided and complete evacuation of all lines leading to sealed system can be accomplished with manifold center hose and connecting branch hose to a cylinder of R-454B and vacuum pump.
3. Attach center hose of manifold gauges to vacuum pump.
NOTICE
Operating Under Vacuum!
Failure to follow these instructions will result in compressor failure. Do not operate or apply power to the compressor while under a vacuum.
4. Evacuate the system to hold a 500 micron vacuum.
5. Close off valve to vacuum pump and observe the micron gauge. If gauge pressure rises above 500 microns in one minute, then evacuation is incomplete or the system has a leak.
6. If vacuum gauge does not rise above 500 microns in 10 minutes, the evacuation should be complete.
NOTICE
Equipment Damage!
Charge with access port on the liquid line only.

Installation

Insulating and Isolating Refrigerant Lines
Insulate the entire suction line with refrigerant piping insulation. Also insulate any portion of the liquid line exposed to temperature extremes. Insulate and isolate liquid and suction lines from each other. Isolate refrigerant lines from the structure and any duct work.
Important: 1. To prevent possible noise or vibration problems, be certain to isolate refrigerant lines from the building.
2. All suction and hot gas bypass piping (if installed) should be insulated from the termination in the air handler to the condensing unit cabinet entry. Failure to do so can cause condensate drip off and performance degradation.
3. Prior to starting a unit, it is advisable to have the approved oils available in the event oil needs to be added to the system.
4. Refer to Split System Air Conditioners Odyssey Application Guide (SS- APG017*-EN) for units needing additional oil and for oil amounts.

NOTICE
Equipment Damage!
This is POE oil, which readily absorbs moisture. Always use new oil and never leave containers open to atmosphere while not in use.

Refrigerant Charging Procedure
If charging by weight, refer to “Charging Levels,” p. 30 for starting change. If refrigerant adjustments are needed because of length of line, refer to the Charging Charts and Superheat values available on unit access panels.

Charge by weight through the gauge port on the liquid line. Follow the requirements listed under A2L Work Procedures section.

Notes: ·

Refrigerant should only be charged in the liquid state.

· When possible, always charge the refrigerant into the liquid line of the unit.

· If the entire charge cannot be charged into the liquid line, the balance of the unit charge can be metered through a charging manifold set as liquid — preferably through a schrader valve into the suction line to the compressor — only while the compressor is running.

· Check and adjust superheat using the superheat table, then re-check charging charts to determine if charge corrections are necessary.

NOTICE
Equipment Damage!
Never charge liquid refrigerant into the suction line of the unit with the compressor off.

Pre-Start
Control Circuit Features
Note: Not all of these features may be required for your unit, check electrical schematic.
Discharge Temperature Limit (DTL)
The control’s sensor is located on the discharge line. This device will shut off the compressor and the outdoor fan(s) if the discharge temperature exceeds the DTL setting. Once the discharge temperature has returned to normal, the compressor will cycle back on.
Low Outdoor Ambient Cooling
All Odyssey units with SymbioTM 700 controls have cooling capabilities down to 0°F as standard. At temperatures below 55ºF for single compressor units and 40ºF for dual compressor units, some reduction in cooling capacity can be expected. At this temperature, equipment can provide approximately 60% of the mechanical cooling capacity. When the optional Low Ambient Accessory kit is field installed, the full capacity of the unit is available down to 0° F.
Evaporator Defrost Control (EDC)
This control is located in the Air Handler. The control’s sensing tube is embedded vertically in the evaporator coil, near the center. This device will stop the compressor if the indoor coil temperature drops below its setting. The indoor air will still circulate across the coil bringing the temperature of the coil back up to the cut-in temperature of the evaporator defrost control.
Low Pressure Cut-Out (LPC)
This control’s sensor is located in the suction (gas) line, near the compressor. This control will stop the compressor and the outdoor fans if suction pressure drops below the Low Pressure Cut-Out setting. Once the suction pressure

has returned to normal, the compressor and outdoor fans will cycle back on.
High Pressure Cut-Out (HPCO)
This control’s sensor is located in the discharge line. This device will shut off the compressor and the outdoor fan(s) if the discharge pressure exceeds the High Pressure CutOut’s setting. Once the discharge pressure has returned to normal, the compressor will cycle back on.
WARNING
Prevent Injury!
Due to agency safety requirements, no schrader core is to be installed beneath the HPCO. Removal of the HPCO without evacuating the system charge could cause injury and release of refrigerant.
Internal Overload Protector (IOL)
This device is embedded in the compressor. It will shut off the compressor if the discharge temperature of the compressor exceeds its design trip temperature. Note: The IOL will put the compressor back in operation
once the compressor motor heat has dropped below the trip setting; however, a check of the refrigerant and electrical systems should be made to determine the cause and be corrected.
Refrigerant Leak Detector Input
All Odyssey units with SymbioTM 700 controls have a dedicated binary input for notification of a refrigerant leak event. This input will receive a normally closed 24 Vac source and when open, triggers a refrigerant leak diagnostic allowing the Symbio 700 to take mitigation actions.

SS-SVX014A-EN

Troubleshooting
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury. When it is necessary to work with live electrical components, have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks.
Refer to the latest version of the SymbioTM 700 Controller with Odyssey Split Systems Applications Guide (ACC-APG001*-EN) for details on troubleshooting the control system.
Leak Detection System
Note: The leak detection system referenced in this document refers specifically to a matched system containing only a TTA/TWE matched combination. If the installed system utilizes condensing units or AHUs other than listed above, it is the installers responsibility to ensure all necessary leak detection system hardware and communication is provided and installed for safe equipment installation and operation.

The leak detection sensor offers a visual diagnostic status in the form of one green and one red LED to indicate diagnostic error state.

Service Test Mode
The SymbioTM 700 supports a Service Test Mode that can be used to energize the various components of the system, either to support general system startup tasks or to support troubleshooting. The user can initiate Service Test Mode through the controller user interfaces, including the Symbio Service and Installation mobile application.
The modes shown below can be initiated. Depending on the equipment configuration, the controller will energize the
Figure 21. Symbio 700 service test mode

appropriate outputs. A user-selected timeout value will determine how long the controller will remain in any given state once initiated. For detailed information on how each Service Test State is interpreted based on the equipment’s configuration, refer to the SymbioTM 700 Controller with Odyssey Split Systems Applications Guide (ACC-APG001*-EN).

Maintenance
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with a CAT III or IV voltmeter rated per NFPA 70E that all capacitors have discharged.
NOTICE
Operating Under Vacuum!
Failure to follow these instructions will result in compressor failure. Do not operate or apply power to the compressor while under a vacuum.
Perform all of the indicated maintenance procedures at the intervals scheduled. This will prolong the life of the unit and reduce the possibility of costly equipment failure.
Monthly
Conduct the following maintenance inspections once per month.
Check unit wiring to ensure all connections are tight and that the wiring insulation is intact.
Inspect the condenser coils for dirt and debris. If the coils appear dirty, clean them.
With the unit operating in the cooling mode, check the suction and discharge pressures and compare them with Pressure Curve values. Record these readings on the “Maintenance Log,” p. 38.
Annually (Cooling Season)
The following maintenance procedures must be performed at the beginning of each cooling season to ensure efficient unit operation.
Perform all of the monthly maintenance inspections.
With the unit operating, check unit superheat and record the reading in the “Maintenance Log,” p. 38.
Remove any accumulation of dust and/or dirt from the unit casing.
Remove corrosion from any surface and repaint. Check the gasket around the control panel door to ensure it
SS-SVX014A-EN

fits correctly and is in good condition to prevent water leakage.
Inspect the control panel wiring to ensure that all connections are tight and that the insulation is intact. Note: Condenser fan motors are permanently lubricated.
Check refrigerant piping and fittings for leaks
Inspect the condenser coils for dirt and debris. If the coils appear dirty, clean them.
Coil Cleaning
Regular coil maintenance, including annual cleaningenhances the unit’s operating efficiency by minimizing:
· compressor head pressure and amperage draw · water carryover · fan brake horsepower · static pressure losses
At least once each year — or more often if the unit is located in a “dirty” environment — clean the coil using the instructions outlined below. Be sure to follow these instructions as closely as possible to avoid damaging the coils.
Microchannel (MCHE) Coils
NOTICE
Coil Damage!
Failure to follow instructions below could result in coil damage. DO NOT use any detergents with microchannel condenser coils. Use pressurized water or air ONLY, with pressure no greater than 600psi. For additional information regarding the proper microchannel coil cleaning procedure, refer to RTSVB83*-EN
Due to the soft material and thin walls of the MCHE coils, the traditional field maintenance method recommended for Round Tube Plate Fin (RTPF) coils does not apply to microchannel coils. Moreover, chemical cleaners are a risk factor to MCHE due to the material of the coil. The manufacturer does not recommend the use of chemical cleaners to clean microchannel coils. Using chemical cleaners could lead to warranty claims being further evaluated for validity and failure analysis.
The recommended cleaning method for microchannel condenser coils is pressurized water or air with a nonpinpoint nozzle and an ECU of at least 180 with pressure no greater than 600 psi. To minimize the risk of coil damage, approach the cleaning of the coil with the pressure washer aimed perpendicular to the face of the coil during cleaning. Optimum clearance between the sprayer nozzle and the microchannel coil is 1-inch to 3-inch.
