6 Drainpipe Installation The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage. CAUTION NOTE ON PURCHASING PIPES Installation requires a polyethylene tube (exterior diameter = 3.7 - 3.9 cm, interior diameter = 3.2 cm), which can be obtained at your local hardware store or dealer. Drainpipe installation for units with a pump Ceiling < 20 cm (7.9 JO) < 55 cm (21.
3. Using a 65 mm (2.5 JO) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle so that the outdoor end of the hole is lower than the indoor end by about 12 mm (0.5 JO). This will ensure proper water drainage (See Fig. 6.5). Place the protective wall cuff in the hole. This XJMM protect the edges of the hole and will help seal it once you finish installation. Units with a pump 1. Remove the test cover. Fill the water pan with 2 liters of water.

9 Air Evacuation Safety Precautions CAUTION • Use a vacuum pump with a gauge reading lower than -0.1MPa and an air discharge capacity above 40 L/min. • The outdoor unit does not need to be vacuumed. DO NOT open the outdoor unit’s gas and liquid stop valves. • Ensure that the Dompound Neter reads -0.1MPa or below after 2 hours. If after hours the gauge reading is still above -0.1MPa, check if there is a gas leak or water inside the pipe. If there is no leak, perform another evacuation for 1 or 2 hours.
Note Pn Adding Refrigerant CAUTION • Refrigerant charging must be performed after wiring, vacuuming, and the leak testing. • DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so can damage the unit or impact it’s functionality. • Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate refrigerant is used. • Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
Test Run Before Test Run A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test: B Indoor and outdoor units are properly installed. C Piping and wiring are properly connected. D No obstacles BSF near the inlet and outlet of the unit that might cause poor performance or product malfunction. E Refrigeration system does not leak. F Drainage system is unimpeded and drainT to a safe location.

Safety General Precautions Introduction 1 Safety Precautions Thank you for purchasing this air conditioner. This manual will provide you with information on how to operate, maintain, and troubleshoot your air conditioner. Following the instructions will ensure the proper function and extended lifespan of your unit. Please pay attention to the following signs: WARNING Failure to observe a warning may result in death. The appliance must be . installed in accordance with national regulations.
Unit Parts Air inlet Electric control cabinet Air filter(on some models) Air outlet Drain hose Refrigerant connecting pipe Fig. 2.1 Operating Conditions Use the system under the following temperatures for safe and effective operation. If the air conditioner is used under different conditions, it may malfunction or become less efficient.
Features Indoor Unit Parts And Major Functions Default Setting Louver Angle Memory Function (Optional) When the air conditioner restarts after a power failure, it will default to the factory settings (AUTO mode, AUTO fan, 24°C (76°F)). This may cause inconsistencies on the remote control and unit panel. Use your remote control to update the status. Some models are designed with a louver angle memory function.
3 Manual Operations This display panel on the indoor unit can be used to operate the unit in case the remote control has been misplaced or is out of batteries. Manual Operations LED display Manual button Operation indicator Timer indicator Infrared receiver Alarm indicator PRE-DEF (pre-heating/defrost) indicator Fig. 3.1 • MANUAL button: This button selects the mode in the following order: AUTO, FORCED COOL, OFF. • FORCED COOL mode: In FORCED COOL mode, the Operation light flashes.
4 Care And Maintenance Safety Precautions Contact an authorized service technician for repair or maintenance. Improper repair and maintenance may cause water leakage, electrical shock, or fire, and may void your warranty. • DO NOT substitute a blown fuse with a higher or lower amperage rating fuse, as this may cause circuit damage or an electrical fire. • Make sure the drain hose is set up according to the instructions.
3. Remove the air filter. 4. Clean the air filter by vacuuming the surface or washing it in warm water with mild detergent. Repairing Refrigerant Leaks WARNING A. If using a vacuum cleaner, the inlet side should face the vacuum. If the refrigerant leaks, turn off the air conditioner and any combustible heating devices, ventilate the room and call your dealer immediately. Refrigerant is both toxic and flammable. DO NOT use the air conditioner until the leak is repaired.
5 Troubleshooting CAUTIONS If one of the following conditions occurs, switch off the power supply immediately and contact your dealer for further assistance. • • • • • The operation light continues to flash rapidly after the unit has been restarted. The remote control buttons do not work. The unit continually trips fuses or circuit breakers. A foreign object or water enters the air conditioner. Other abnormal situations.
Problem Possible Causes Dust is emitted from either the indoor or outdoor unit The unit emits a bad odor The fan of the outdoor unit does not operate The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity. The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
