Failure to observe these warnings may result in death, injury, or damage to the equipment. Be sure to observe all of them without fail.

• If the air conditioner appears to be operating abnormally (e.g., smell of something burning), switch the air conditioner off at the main switch and contact your dealer. Continued operation may result in failure, electric shock, or fire.

• Only use a qualified installer for installation. Incorrect installation may result in water leakage, electric shock, or fire.

• Ask your dealer to carry out improvements, repairs, and maintenance. Incorrect work may result in water leakage, electric shock, or fire.

• Never remove any fixed covers on the indoor or outdoor unit, as this may expose fast-moving fan blades or hazardous voltage components, leading to injury or electric shock.

• If the unit is installed in an unventilated room, take measures to prevent refrigerant concentration from exceeding allowable limits in case of a leak, which could cause drowsiness or asphyxiation.

• For separately sold component parts, ask a specialist for installation. Incomplete installation may result in water leakage, electric shock, or fire.

• Ask your dealer to move and reinstall the air conditioner. Incomplete reinstallation may result in water leakage, electric shock, or fire.

• Never insert any objects into the openings in the indoor or outdoor unit.

• When used with burners or heaters, ensure sufficient ventilation to avoid an oxygen deficiency accident.

• Regularly check the quality of the foundation blocks. If damaged, the unit may fall and cause injury.

• Do not place or use a flammable spray can near the air conditioner.

• To clean the unit, stop the operation and switch the power off at the main switch to avoid electric shock and injury.

• Do not expose the indoor unit or remote controller to rain or moisture.

• Always replace any blown fuse with a fuse of the same specification.

• Do not place a burner or heater in a place directly exposed to the airstream from the unit, as this may result in incomplete combustion.

• Do not wash the air conditioner with water, as an electric shock may result.

• Do not install the unit in an area where flammable gas may be present.

• Avoid prolonged exposure of your body to direct streams of cold air.

• This product contains Refrigerant Type: R32. Do not charge R32 into systems other than those designated for R32, use oil other than that designated for R32, or use a reclaim cylinder other than an R32 reclaim cylinder. Do not install pipework with diameters not specified for the model.

Failure to observe a caution may result in injury or damage to the equipment.

• Do not use the air conditioner for special applications such as storage of foods, animals and plants, precision machines, and art objects, as deterioration of quality may result.

• Ensure drain piping is completed. Incomplete piping may result in a water leakage.

• Do not expose animals and plants directly to the airstream from the outdoor unit.

• Never operate the air conditioner without the return air filter(s) in place. Operating the unit without the filter(s) will allow dust to enter the indoor unit and build up on the heat exchanger coil and fan motor, which will cause a malfunction not covered by warranty.

• This electrical appliance is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that they do not play with the outdoor unit.

• Carefully read the operation manual supplied with your controller.

• Ensure that your installer shows you the location of the main power switch of the air conditioning system, which is normally located adjacent to the outdoor unit or in the fuse box/switchboard.

• The main switch must be turned on at least 6 hours before the air conditioner is operated to warm up the compressor. Failure to do so may result in damage to the compressor which will not be covered by warranty.

• Ensure that there are no obstacles near the air outlet of the outdoor unit, such as plants, boxes, or fences.

• Ensure the air filter is installed in the return air grille.

• If applicable, ask your installer to verify the minimum number or combinations of zones required to be operating before starting your unit.

If the TCL TCD140D1HWH-DV air conditioner is operating during a power failure, it may automatically restart in the same mode when the power is restored.

Observe the following precautions to ensure the system operates efficiently:

• Adjust the room temperature for a comfortable environment. Avoid excessive heating or cooling.

• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.

• Keep doors and windows closed to prevent room air from flowing out, which decreases the effect of cooling and heating.

• Never place objects near the air inlet and the air outlet of the unit.

• Turn off the main power supply switch when not using the unit for long periods to save energy. Turn the main power supply switch back on 6 hours before restarting operation to ensure smooth operation.

• Ventilate the room regularly, as using the unit for long periods requires regular ventilation.

If the temperature or humidity is outside the following conditions, safety devices will continue to function, but the TCL TCD140D1HWH-DV air conditioner system may not operate as normal. DB stands for Dry bulb temperature.

• A continuous low “shuh” sound is heard when the system is in COOLING or DEFROST OPERATION. This is the sound of refrigerant gas flowing through both indoor and outdoor units.

• A “shuh” sound heard at the start or immediately after the stop of operation, or at the start or immediately after the stop of DEFROST OPERATION, is the noise of refrigerant stopping or changing direction.

If the air conditioner is in an abnormal condition (smell of something burning, etc.), switch off the main switch, and contact your TCL dealer or TCL appointed maintenance center. Continued operation under such circumstances may result in a failure, electric shock, or fire.

If a safety device such as a fuse, a circuit breaker, or an earth leakage circuit breaker frequently actuates, or the ON/OFF switch does not work properly, you should turn off the main power switch and contact your TCL dealer.

If water leaks from any location besides the drain pipe on the indoor unit, stop the operation and contact your TCL dealer.

If a 2-digit fault code appears on the LCD screen, write down the fault code and then stop the operation. Notify your TCL dealer or TCL appointed maintenance center and inform them of the displayed code.

If the system does not operate properly and none of the other malfunctions are evident, investigate the system according to the following procedures:

• Check if there is a power failure. Wait until power is restored. If a power failure occurs during operation, the system may automatically restart immediately after the power supply recovers.

• Check if the fuse has blown or the circuit breaker has tripped. Please contact and notify qualified technicians to check.

• Check if the air inlet or outlet of the outdoor or indoor unit is blocked by obstacles. Remove the obstacle and make it well-ventilated.

• Check if the air filter is clogged. Clean the air filter(s) (Refer to MAINTENANCE).

• Check if the air inlet or outlet of the indoor or the outdoor unit is blocked with obstacles. Remove the obstacle and make it well-ventilated.

• Check if the air filter is clogged. Clean the air filter(s).

• Check if the set temperature is within a comfortable range.

• Check if the FAN SPEED CONTROL button is set to high. If you normally use low fan speed, ensure the air filter is clean.

• Check if the doors or the windows are open. Shut doors or windows to prevent wind from coming in.

• Check if direct sunlight enters the room (when cooling). Use curtains or blinds.

• Check if there are too many occupants in the room (when cooling). Cooling effect decreases if the heat gain of the room is too large.

• Check if the heat source of the room is excessive (when cooling). Cooling effect decreases if the heat gain of the room is too large.

1. Confirm that the air inlet and outlet are not blocked. Remove any obstacle.

2. Clean the air filter(s). After cleaning, make sure to reattach it.

3. Turn on the main power supply switch. The display on the wired controller will be shown when the power is turned on. To protect the unit, turn on the main power switch at least 6 hours before operation.

• Turn on FAN OPERATION for a half day to dry the unit.

• Cut off the power supply. When the main power switch is turned on, some power is being used even if the system is not operating. Turn off the main power supply switch for saving energy. The display on the wired controller will vanish when the main power switch is turned off.

IMPORTANT! NO USER SERVICEABLE PARTS ARE INSIDE THE AIR CONDITIONER. DO NOT REMOVE ANY ACCESS PANELS OR FIXED COVERS.

• Before cleaning the air conditioner, be sure to stop operation and turn the power switch off. Otherwise, an electric shock and injury may result.

• Do not wash the indoor unit with water, as this may result in an electric shock. Be careful erecting scaffolding and exercise caution when working at a height.

• Be sure to always clean the air filter(s) before use at the beginning of summer and winter. Dirt and dust caught in the air filter cause a drop in airflow, which leads to a decline in performance.

• When using the unit in a location where dirt may easily accumulate, clean the filter(s) more frequently. Once every 2 weeks is recommended.

Note: The air filter(s) and the suction grille(s) are supplied by your dealer. Ask your dealer how to clean them.

Clean with a soft cloth. When it is difficult to remove stains, use water or neutral detergent.

NOTE:

• Do not use gasoline, benzene, thinner, polishing powder, or liquid insecticide. It may cause discolouring or warping.

• Do not let the indoor unit get wet. It may cause an electric shock or a fire.

In the unlikely event that a fault develops, the microprocessor in the indoor and outdoor units will diagnose the fault (where possible), and a unique 2-digit fault code will display on the LCD screen (e.g., E0). If this occurs, write down the fault code, switch off the unit, and contact your installer. This code will indicate to the installer/repairer what the problem may be.

This is a normal symptom. You should wait one minute until the microcomputer is prepared for operation.

This is a normal symptom. The outdoor unit stops because the room temperature has reached the set temperature. The indoor unit then switches to fan operation.

This is a normal symptom that occurs when the system reverts to HEATING OPERATION after a DEFROST OPERATION. The moisture generated by the defrost process becomes steam and is discharged as a white mist.
