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).

· Leaving water temperature deltas range from 10°F to 15°F.
· Maximum water pressure allowed in system is 400 psi.
Controls
The available control type is a Deluxe 24V control option, a SymbioTM 400-B control option for all unit sizes.
All power wiring to the equipment is made at the unit’s compressor contactor or optional disconnect switch for the EXH/V 0.75 to 6 ton units and the DXH/V 2 to 6 ton units. For units without the disconnect switch, the power wiring needs to be connected to the screw terminals of the compressor contactor. All low-voltage wiring is made at the unit’s low voltage terminal plug.
System Input Devices and Functions
A thermostat, zone sensor, or building automation system is required to operate the water-source heat pump. The flexibility of having several mode capabilities depends upon the type of sensor and/or remote panel selected.
Troubleshooting and connection diagrams for the 24V control systems may be located in the back of this manual. All digital control troubleshooting tips and connection

diagrams are located in SymbioTM 400­B/500 Programmable Controllers Water Source Heat Pump (WSHP) Installation, Operation, and Maintenance guide (BAS- SVX092-EN).
Deluxe 24V Controls (option)
Units containing the Deluxe 24V control design will incorporate a microprocessor-based control board. The Trane microprocessor board is factory wired to a terminal plug to provide all necessary terminals for field connection. The deluxe board is equipped with a random start relay, anti-short cycle timer, brown out protection, compressor disable, condensate overflow, unit safety control, diagnostics, and a generic relay (which may be available for field use).
SymbioTM 400-B (option)
The Symbio 400-B is a BTL Listed BACnet® controller that can operate stand- alone or within a Building Automation System (BAS) such as Tracer® SC+. For installation, operation, and maintenance, see SymbioTM 400­B/500 Programmable Controllers Water Source Heat Pump (WSHP) Installation, Operation, and Maintenance guide (BAS-SVX092-EN).
Pump Module (Field Installed Accessory)
The pump module consists of either a single or dual 1/6 HP cast iron pump and a brass three-way shut-off valve. The pump module kits contains the necessary components for the installation, operation, and maintenance of the water circuit of a closed-loop distributed pumping application.
Waterside Economizer (Option)
Instructions for mechanical connection of the waterside economizer to the water-source heat pump may be found in the dimensional section of this manual.
The waterside economizer is designed to begin economizing mode when water temperatures fall below the field adjustable temperature of 25, 35, 45, 55 or 60°F (for the Deluxe control option), or below the programmed setpoint (for the SymbioTM 400-B control option).
When the temperature is less than the setpoint, fluid will flow into the economizing coil, while simultaneously halting mechanical operation of the compressor. Mechanical cooling will continue on a call for a second stage from the thermostat or system control. Entering water temperature sensor is factory provided for field installation on the entering water side of the coil.
WSHP-SVX019A-EN

Boilerless Control/Electric Heat (Option)
This option targets building designs that do not incorporate a boiler to heat the loop system. During a heavy heating load, the loop temperature may begin to fall. As the loop temperature decreases, the heating capacity of the heat pump also decreases. In the heating mode, when the loop temperature falls below 55°F (factory setting), the electric heater is energized, and the compressor is locked out. The system’s electric heat source is utilized for primary heating until the loop temperature rises above 60°F. Once the loop temperature rises above 60°F, the boilerless controller returns the unit to normal compressor heating operation and locks out the electric heater.
The electric heat must be field installed by the contractor.
Note: The boilerless controller has a field adjustable entering water temperature setting of 25, 35, 45, 55, and 60 degrees. The compressor operation will return to normal operation when the loop temperature rises 5 degrees above the setpoint. This electric heat option is designed for primary heat only, not to run as supplemental heat to the heating function of the heat pump.

Risk of Fire — Flammable Refrigerant!
Failure to follow instructions below could result in death or serious injury, and equipment damage.
· To be repaired only by trained service personnel.
· Do not puncture refrigerant tubing.
· Dispose of properly in accordance with federal or local regulations.
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
Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.
The units described in this manual use R-454B refrigerant. Use ONLY R-454B rated service equipment or components with these units. For specific handling concerns with R-454B, contact your local Trane representative.
Installation, repair, removal, or disposal should be performed by trained service personnel.
At all times, Trane’s maintenance and service guidelines shall be followed. If in doubt, contact Trane technical support for assistance.
Servicing
Prior to initiating work on equipment, check the area with an appropriate refrigerant detector. Ensure the service personnel are properly trained regarding work in potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately
WSHP-SVX019A-EN

sealed, or intrinsically safe. Be aware that the refrigerant does not contain an odor.
If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing equipment shall be available on hand. A dry powder or CO2 fire extinguisher should be located adjacent to the charging area.
At all times, Trane’s maintenance and service guidelines shall be followed. In in doubt, contact Trane technical support for assistance.
All maintenance staff and others working in the local area shall be instructed on the nature of the work being carried out. Work in confined spaces shall be avoided.
Ignition Source Mitigation
Do not use any sources of ignition when working on the refrigeration system.
Keep all ignition sources, including cigarette smoking, away from the site of installation, repair, removal or disposal, during which refrigerant can potentially be released to the surrounding space.
Survey the area around the equipment before initiating work to ensure no flammable hazards or ignition risks are present.
“No Smoking” signs shall be displayed.
Do not use devices that can be a source of ignition to accelerate defrosting of components. Use only defrost and cleaning procedures recommended by Trane. Do not pierce or burn.
Ventilation
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. If present, check that the ventilation system, including outlets, are operating adequately and are not obstructed.
Refrigerating Equipment
Refrigerant piping or components should not be installed in locations where substances which may corrode them are present.
Check that equipment hazard markings are visible and legible. Replace them if they are not.
For equipment using secondary fluids, like water or glycol, check that refrigerant is not present in the secondary fluid loop before conducting any hot work.
Electrical Devices
Do not apply power to the circuit if a fault exists which compromises safety. If the fault cannot be corrected immediately, but it is necessary to continue operation, an
27

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:
28

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.
WSHP-SVX019A-EN

· 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
WSHP-SVX019A-EN

A2L Information
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. When equipment has been decommissioned, attach a signed label which includes the date of decommissioning.
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 ductwork and 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
29

A2L Information

installed accessory electric heaters, gas heaters, relays, and contactors) were evaluated during product UL listing.
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, 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 required.
· 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.

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 installation height (in meters) / actual installation 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 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 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.
WSHP-SVX019A-EN

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 20mm above the floor covering surface.
· Natural ventilations opening areas must meet the requirements of ANSIASHRAE Standard 15-2022, Section 7.2.3.2.
31

A2L Information
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 Trane-approved sensors when replacement is required.

(12.7 mm) thick and equal to the overall unit foot print.
Hanging the Horizontal Unit
WARNING
Proper Structural Support Required!
Failure to ensure proper structural ceiling support could result in unit falling from its location which could result in death or serious injury. Ceiling structure must be strong enough to support the weight of the unit and any accessories. If unsure, check with a structural engineer.

1. Install the hanging isolators (located in the control box from factory) into the six hanging brackets.
2. Use a lift with a large supporting surface or a wooden structure supporting the base of the unit (hanging rails) when the unit is lifted for installation.
3. Secure the equipment to a joist, concrete, etc. with the use of 3/8 in. (9.7 mm) field provided (all-thread) rod. Each rod should contain field provided nuts and washers to complete the hanging installation.
4. All plumbing to the unit should conform per national and local codes and is the responsibility of the contractor. The 0.5 to 6 ton horizontals and EX/DXHK models do not need to be sloped. EXHK and DXHK 0.75 to 6 ton models must be installed level. The 0.5 to 5 ton horizontal models do not need to be sloped and must be installed level.
Note: Rods must be perpendicular to the mounting holes in the base rail of the horizontal unit.

CLEAN OUT ( CAPPED and SEALED)
Install proper trapping to the equipment. The unit drain connection is 0.75 in. NPT for all DXH, DXV, and EXH/V 0.75 to 6 ton models. When designing the condensate trap for the water-source system, it is important to consider the unit draw through design requiring negative pressure trapping. In a properly trapped system, when condensate forms during normal operation, the water level in the trap rises until there is a constant flow. It is imperative to maintain water in the trap and not allow the trap to dry out during heating season. Keeping trap primed at all times will enable the water to flow properly. See the figure above for appropriate dimensions required in a negative pressure system.

RETURN TO LOOP
SUPPLY FROM CENTRAL PUMP

Connect the supply and return hoses to the water-inlet (from supply) and water-outlet (to return) of the unit. For vibration isolation, it is recommended that flexible steelbraided hoses be installed instead of hard piping the equipment to the main loop system. Figure above shows connection of a Hays Mesurflo® balancing hose kit to the water-in and water-out of a vertical unit. Note: Above figure example incorporates the Hays
Mesurflo® balancing hose kit and a 2-position isolation valve into the system design. An isolation valve is often used in variable speed pumping applications and is designed to stop water flow to the unit during non operation times. This allows the loop water pumps to run only when a requirement for pumping is needed for greater energy efficiency of the overall system design.
Cleaning and Flushing the Water Loop
After the piping system is complete, the flexible hose connectors should be doubled back to complete the water circuit external to the unit (avoiding trash settle-out in the condenser). An extra pipe may be necessary to connect the hose kits.
1. Water circulation system should be filled with clean water using the water make up connections.
Note: Air vents should be open during filling.
2. With the air vents closed, start the circulating pump and then crack the air vents to bleed off the trapped air to confirm circulation through all components of the system.
Note: Make up water must be available to the system to replace the volume formerly occupied by the air that is bled off.
3. With the air vented and the water circulating, the entire system should be checked for leaks and repaired as required.
4. Operate the supplementary heat system (boiler) making checks per manufacturer’s instructions. During this operation, visual checks should be made for leaks

Installation
that may have occurred due to increased heat. Repair as required.
5. Open the system at the lowest point for the initial blow down (making sure the make up water is equal to the water being dumped). Continue blow down until the water leaving the drain runs clear, but not less than 2 hours.
6. Shut down pumps and supplementary heat system. Reconnect the hoses placing the water-to-refrigerant heat exchanger in the water circulating system.
Note: Vents should be open when the pumps and supplementary heat system are shut down.

Waterside Economizer Start-Up Sequence

1. Set the thermostat to the highest position.
2. Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.
3. Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/ temperature plugs and comparing to tables contained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9 to 12ºF); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit.
4. Check the cooling refrigerant pressures against values in “,”.
Note: If cooling mode is activated, and the entering water temperature of the heat pump falls below 55ºF, the 2-position, water side economizing valve will become energized (open) and compressor operation will halt allowing for free cooling in the space.
5. Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-energize.

6. Leave unit off for approximately FIVE minutes to allow for pressure equalization.
7. Turn the thermostat to the lowest setting.
8. Set the thermostat system switch to the HEAT position.
9. Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5 to 9°F leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.
10. Check the heating refrigerant pressures against values in “,”.
Note: For units with boilerless electric heat option: In heating mode, if the entering water temperature of the heat pump falls below 45ºF, the electric heater will be energized, and compressor operation will halt. Once the entering water temperature rises above 50ºF, the boilerless controls returns the unit.
11. Set the thermostat to maintain the desired space temperature.
12. Instruct the owner on system operation.

Pre-Start Checklist
Before energizing the unit, the following system devices must be checked:
· Is the high voltage power supply correct and in accordance with the nameplate ratings?
· Is phasing of the unit correct per compressor rotation (scroll compressor only)?
· Is the field wiring and circuit protection the correct size?
· Is the low voltage control circuit wiring correct per the unit wiring diagram?
· Is the piping system clean/complete and correct? (A recommendation of all system flushing of debris from the water-to-refrigerant heat exchanger, along with air purging from the water-to-refrigerant heat exchanger be done in accordance with the Closed-Loop/Ground Source Heat Pump Systems Installation Guide).
· Is vibration isolation provided? (i.e. unit isolation pad, hose kits)
· Is unit serviceable? (See clearance specifications in Unit Dimensions and Weights).

· Are the low/high-side pressure temperature caps secure and in place?
· Are all the unit access panels secure and in place?
· Is the thermostat in the OFF position?
· Is the water flow established and circulating through all the units?
· Is the duct work correctly sized, run, taped, insulated and weather proofed with proper unit arrangement?
· Is the condensate line properly sized, run, trapped, pitched and primed?
· Is the zone sensor correctly wired and in a good location?
· Does the indoor blower turn freely without rubbing?
· Has all work been done in accordance with applicable local and national codes?
· Has heat transfer fluid been added in the proper mix to prevent freezing in closed system application?

Start-Up

Initial Unit Start-Up
Note: Start-up with the heat pump thermostat is included below:
1. Set the thermostat to the highest position.
2. Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.
3. Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/ temperature plugs and comparing to tables contained in specification sheet data.
4. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 912ºF); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit.
5. Check the cooling refrigerant pressures against values in “,”.
6. Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-energize.
7. Leave unit off for approximately FIVE minutes to allow for pressure equalization.
8. Turn the thermostat to the lowest setting.
9. Set the thermostat system switch to the HEAT position.
10. Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5-9ºF leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.
11. Check the heating refrigerant pressures against values in “,”.
12. Set the thermostat to maintain the desired space temperature.
13. Instruct the owner on system operation.

Date:
Serial Number:
To minimize troubleshooting and costly system failures, complete the following checks and data entries before the system is put into full operation.
Operating Pressures
There are many variables (airflow, air temperatures) in an air conditioning system that will affect operating refrigerant pressures and temperatures. The charts below shows approximate conditions and is based on air flow at the rated SCFM, entering air at 80.6°F (DB), 66.2°F (WB) in cooling, 68°F (DB) in heating. (+)Heating data with 35°F EWT is based on the use of an anti-freeze solution having a freezing point 20°F lower than the minimum expected entering temperature.
