Operating Precautions
This system must be installed properly by a qualified installer in accordance with installation instructions.
Anti-Recycle Timer
- The control system has a build-in 3 minute anti-recycle timer which helps to preserve the life of system components.
- Anti-Recycle Timer will operate as circumstances occur during operation of unit:
• Temperature setting wheel is
adjusted back and forth.
• ON/OFF switch is turned ON
and OFF.
• Room temperature reaches the
set point.
• Power failure.
Power Failure Recovery
- Saves settings during a power failure and restarts automatically when power resumes.
Freeze Protection
The system is protected against low indoor coil temperatures. Under certain conditions, the “COOL/DRY” LED will blink indicating the protective function has been activated. There is no need to adjust the system.
Stop The Air Conditioner At Once If Any Of The Following Occurs:
- The power cord is too hot to be touched by hand.
- The insulation of the power cord is exposed at any point.
- The fuse is blown or circuit breaker trips frequently.
- The functions of the switches are inaccurate.
System Operation
Operating Air Conditioner Safety
- Do not insert a bar or similar object into the supply air grille. In particular, advise small children not to insert anything in the grille.
- Do not pour water directly on the air conditioner to clean it. If the air conditioner is operating as wet, grounding may occur, damaging the unit.
- Adjust the air flow, so it does not blow directly on room occupants.
- Do not use flammable sprays near the air conditioner because of danger of fire.
- Do not use a steel or copper wire in place of fuses.
- Do not inspect or service the air conditioner while it is operating. Turn off the power supply before doing any inspection or service work.
- The power cord should be kept away from furniture with sharp corners. It may cause fire or electric shock.
- When the air conditioner will not used for a long time, be sure to turn OFF the power supply.
If you have any questions or problems with your air conditioning system, please consult your nearest Trane dealer.

Note: Once the air filter is washed,
dry it completely before returning it to its original position. After cleaning, be sure to return it to its original position.
Cautions
- Do not wash the air filter in water that is over 400C or it may shrink.
- Do not expose the air filter to fire.
- Do not expose the air filter to direct sunlight for a long time.
- Clean the air filter more frequently when the air is very dirty.
Maintenance
Regular Maintenance
Be sure to disconnect the power before inspection or maintenance of air conditioner.
1. Cleaning the air filter
Air flow is reduced and cooling efficiency impaired if the filter is clogged. Be sure to clean the filter every two weeks during the cooling season.
1.1 How to remove the air filters
- Remove each return air grille by pushing down and pulling forward
- Remove each air filter frame from the return air grille
1.2 How to clean the air filter
Wash away dust from the air filter with clean water or vacuum it with an electric vacuum cleaner.
Pull
Pull
Pull Upward
2. Cleaning the front panel
Do not pour water directly on the front panel to clean it. Dust or wipe it lightly with a soft cloth. If it is very dirty, use a soft cloth soaked in water or neutral detergent.
Cautions
- Do not use water over 500C to clean the front panel or it may become discolored.
- Do not use benzine, gasoline, thinner, polishing compound, machine oil, etc. when cleaning the front panel, or paint may peel off, or it may become deformed or damaged.
3. Maintenance before prolonged idle period
- Operate the fan for about half a day to dry the inside of the unit.
- Stop the air conditioner and disconnect the power by turning off the safety breaker.
- Clean the air filter and return it to its original position.
- Place the protective cover over the condensing unit.
- Outdoor unit internal components must be cleaned periodically.

Troubleshooting
Before calling for service, please check the following.
The air conditioner does not operate at all:
- Check if the control ON/OFF switch is “OFF”. Turn the switch to ON.
- Check whether the fuse has been blown or circuit breaker thrown. Set the ON/OFF Control Switch to OFF, and turn on the circuit breaker or replace to a new fuse.
- Check whether the power supply is interrupted. Wait until the power is resupplied and then operate the air conditioner.
Cooling is insufficient:
- Check whether the air filter is clogged. Clean it.
- Check whether the thermostat setting is too high. Set the thermostat to lower temperature.
- Check whether windows or doors are opened. If opened, close it.
- Check whether there are sources of heat in the room, cooling is less effective.
- Check whether the return air inlet or the supply air outlet on the indoor unit and outdoor unit are blocked. If they are blocked, remove obstacles to make air passage clear.
- Check whether the fan speed is set at low. Set the fan switch from “LOW” to “MED” or “HIGH”
Heating is insufficient:
- Check to see if the air filters are clogged with dust or debris. Clean the air filters.
- Check to see if the thermostat setting is too low. Set the thermostat a higher temperature.
- Check to see if windows or doors are open. If they are open, close.
- Check to see if the return air inlet or the supply air outlet on the indoor unit are blocked. If they are blocked, remove obstacles to permit air passage properly.
- Check to see if the fan speed is set at low setting. Set the fan switch from “LOW” to “MED” or “HIGH”
