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

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.

NOTICE

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.
In contrast to common refrigerants, R32 does no harm to the ozonosphere and has a significantly lower greenhouse warming potential when compared to previous 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

· Children should not clean or maintain the unit without supervision.
· Keep children from playing or climbing on the air conditioner.
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
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.
WARNING
Power Cord!
If the SUPPLY CORD is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

All Units

Important: Follow NEC and local electrical codes when installing electrical supply wiring. The following is only shown as a sample.
Use recommended wire size (Table 1) and install a single-branch circuit. All units are designed to operate off only one (1) single branch circuit.
Note: Only use copper conductors. Branch circuit wire is single circuit from main box. AWG wire sizes are based on copper wire at a 140°F (60°C) temperature rating.

Power Connection Options
Appropriate power cord accessory kit is determined by the voltage and the amperage of the branch circuit, based on the unit amperage requirements (for example, electric heater size). This unit ships without a power cord (or hard wire kit). An accessory power cord must be ordered to connect the unit to the outlet.
Notes:
· Ensure the outlet matches the appropriate prong configuration on the plug. It should be within reach of the service cord. All wiring, including installation of the receptacle, must be in accordance with the NECTM and all local codes, ordinances and regulations. National codes require the use of an arc fault or leakage current detection device on all 208/230V power cords.
· For 265V units, if power cord accessory option is selected, then the cord is only 18″ long and must plug into the accessory electrical 265V sub-base.

Grounding
For safety and protection, the unit is grounded through the service cord plug or through separate ground wire provided on hard wired units. Ensure that the branch circuit or general purpose outlet is grounded.
Voltage Supply
Check voltage supply at outlet. For satisfactory results, the voltage range must always be within the ranges specified on the data information plate. Power cord does not ship with the unit. The cord to order is determined by the unit voltage and the desired electric heat capacity.
Cord/Connected Units
The 250 Vac field supplied outlet must match the plug for standard 208/230V units and be within reach of the service cord.
Note: Do NOT use 30 amp cord with sizes 07 and 09 units.

Power Cord Protection
The power cord for 230/208V units provide protection from fire. The unit power automatically disconnects when unsafe conditions are detected. Power to the unit can be restored by pressing the reset button on plug head. Upon completion of unit installation for 230/208V models, an operational check should be performed using the TEST/RESET buttons on the plug head.

Note: Models with 265V do not incorporate this feature because they require use of an electrical subbase accessory. Connection to a wall socket is not permitted for 265V units. All 265V units must be hard wired using the hard wire kit or make use of the plug-in receptacle in the standard subbase.

Installation
Trane Wall Sleeve and Grille
The image below shows the typical unit components that are ordered and installed.
Important: Proper installation is the responsibility of the installer. Product failure due to improper installation is not covered under warranty.
Note: To install the Trane Wall Sleeve and Grille, refer to the latest installation instructions, PTACSVN028 and PTAC-SVN027.
Considerations for Use of Existing Sleeves
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.

In applications when the unit is a replacement, it is recommended to use a Trane sleeve. This unit can be retrofitted to other manufacturers similar sleeves if outdoor unit airflow is not restricted or recirculated. Important: Ensure the outdoor grille is installed on the
sleeve. For any sleeve retrofit applications, be sure that the foam seals (factory installed on the tube sheets) provide a good seal between the grille and outdoor coil tube sheets. These foam seals provide a barrier that stops the inside air from mixing with the outside air (known as air recirculation).
Important: Inspect the wall sleeve thoroughly prior to installation. The manufacturer does not assume responsibility for costs or damage due to defects in the sleeve or for improper installation.
Remove any existing foam baffles installed on competitor’s outdoor grille.

as Low fan or Hi fan), the fan speed is determined by how the terminal connector is wired. When using Low fan speed, wire the GL output from the thermostat to GL on the terminal block. When using Hi fan speed, wire the GH output from the thermostat to GH on the terminal block. .
Energy Management Input (Front Desk Control)
The controller can handle a switch signal from remote energy management input, called an EM signal or front desk control. The input must be 24 Vac. When the system receives a 24 Vac signal, it turns OFF the unit; otherwise it is in normal control. This function is disabled under Freeze Guard protection.
Intelligent Self-Checking Control
The PTAC has an on-board computer continuously checks key components of the unit to ensure they are operating properly. Under normal operation, the unit status indicator (STATUS, on main PCB), light is steadily ON. If there is a major problem, the unit shuts down and displays a diagnostic failure code on the control. If it is a minor error and the unit can correct it by itself, the diagnostic code is flashed on the status LED that is easily seen when the front panel is removed. Refer to the following table of diagnostic codes.
Notes:
· When using a room thermostat, diagnostic codes are not viewable. These codes are only viewable on the unit control board.
· After the compressor cycles three times the F0 code can appear if the refrigerant charge is low.

Mode Functions
Cooling Mode Functions
· When the ambient temperature is 2°F above setpoint, the unit operates under cooling. Both the outdoor fan and indoor fan operate in the set speed. When the starting condition of compressor is reached, outdoor fan operates and compressor begins operation 10 seconds later.
· When the ambient temperature reaches 2°F below setpoint, the unit stops operation, whereby, the compressor and outdoor fan stop operation. Under indoor fan cycle mode, the indoor fan stops operation after operating at set fan speed for 60 seconds (except when it requires the indoor fan to operate in protection mode). If the fan cycle mode is not selected, the indoor fan operates at the set fan speed.
· When the indoor fan is set at high speed, the outdoor fan operates at high speed.
· When the indoor fan is set at low speed, outdoor fan operates at low speed.
· When the unit starts in cooling mode for the first time and the indoor fan is set to low speed, the outdoor fan starts at high speed. After operating for 3-1/2 minutes and the outdoor tube temperature is below 140°F (60°C), the outdoor fan switches over to low speed. First time start-up includes, when switching to low speed cooling from non-cooling mode or when the unit starts low speed cooling for the first time or enter low speed cooling after a power failure.
· During cooling mode, and when there is no outdoor condenser high temperature condition, the unit stops:
­ When it reaches the setpoint.
­ When the unit stops for a temperature sensor error.
­ When the unit stops for freeze protection.
­ When the start-up condition of outdoor fan is met.
­ When the indoor fan operates at high fan speed for 3 seconds and then turn to set fan speed.
If high temperature protection occurs during cooling mode, the outdoor fan is forced to operate at high speed. When the start-up

The set temperature and fan speed will keep the same when switching modes.
Function
For Heat Pump (General Type)
Note: The electric heater and compressor cannot operate at the same time.
· When ambient temperature of the space is 2°F below setpoint, the compressor operates in heating mode. The four-way valve and both the indoor/ outdoor fans start operation at set speed. After 10 seconds, the compressor begins operation. If the compressor operates and satisfies the setpoint and minimum operation time of the compressor, then both the compressor and indoor/outdoor fans deenergize. If the compressor does not meet setpoint and the ambient temperature drops to 5°F below setpoint, the compressor de-energizes and after one second, the electric heater starts. The electric heater remains in operation until the setpoint +2°F is satisfied.
Note: The minimum compressor run time is 6 minutes
· When there is a call for heat and the compressor cannot be energized due to the protection function, the electric heat energizes after 15 seconds and remains energized until the setpoint +2°F is satisfied.

Technicians Guidelines
Aptitude requirement for maintenance man (repairs should be done only be specialists).
1. Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from an industry-accredited assessment authority, which authorises their competence to handle refrigerants safely in accordance with an industry recognised assessment specification
2. Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring the assistance of other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable refrigerants.
Safety preparation work
The maximum refrigerant charge amount is shown on the table below:
Note: Please refer to the nameplate for the charging quantity of R32.
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system.
· Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed.
· General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
· Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to

ensure the technician is aware of 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 sealed or intrinsically safe.
· Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
· No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.
· Ventilated area
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.
· Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer s ‘ technical department for assistance.

36

PTAC-SVX004A-EN

The following checks shall be applied to installations using flammable refrigerants:
­ The actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are installed;
­ The ventilation machinery and outlets are operating adequately and are not obstructed;
­ If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
­ Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
­ Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components perare constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
· Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an 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:
­ That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
­ That no live electrical components and wiring are exposed while charging, recovering or purging the system;
­ That there is continuity of earth bonding.
Repairs to sealed components
During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of
PTAC-SVX004A-EN

Troubleshooting and Resources
protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
· Ensure that the apparatus is mounted securely.
· Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications
Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating.
Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
Note: The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.
Cabling:
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
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 re-calibration. (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 of the refrigerant and shall be calibrated to the refrigerant employed, and the appropriate percentage of 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.
37

Troubleshooting and Resources
Notes: 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 leakage of refrigerant is found which requires brazing, all of the 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. Removal of refrigerant shall be according to Clause Removal and evacuation.
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:
1. safely remove refrigerant following local and national regulations;
2. purge the circuit with inert gas;
3. evacuate (optional for A2L);
4. purge with inert gas (optional for A2L);
5. open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For appliances containing flammable refrigerants, 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.
For appliances containing flammable refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge is used, the system shall be vented down to atmospheric pressure to enable work to take place.
Ensure that the outlet for the vacuum pump is not close to any potential ignition sources and that ventilation is available.
Charging procedures
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 minimise the amount of refrigerant contained in them.
38

· Cylinders shall be kept in an appropriate position according to the instructions.
· Ensure that the refrigeration 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 refrigeration system.
Prior to recharging the system, it shall be pressure tested with the appropriate purging gas.
The system shall be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. 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 reuse of reclaimed 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:
· mechanical handling equipment is available, if required, for handling refrigerant cylinders;
· all personal protective equipment is available and being used correctly;
· the recovery process is supervised at all times by a competent person;
· 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 manufacturer’s 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 the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
PTAC-SVX004A-EN

11. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
Labelling
Equipment shall be labelled stating that it has been decommissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leakfree disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.
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

Troubleshooting and Resources
not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
