GB - 12 42HQE009 / 012 / 018 / 022 Operation tips The following events may occur during normal operation. 1. Protection of the air conditioner. Compressor protection • The compressor can't restart for 3 minutes after it stops. Anti-cold air (Cooling and heating models only). • The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. A) When heating has just starting. B) Defrosting. C) Low temperature heating. • The indoor or outdoor fan stop running when defrosting (Cooling and heating models only). Defrosting (Cooling and heating models only) • Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high resulting in lower heating efficiency of the air conditioner. • During this condition air conditioner will stop heating operation and start defrosting automatically. • The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost buildup on the outdoor unit. 2. A white mist coming out from the indoor unit • A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode in an indoor environment that has a high relative humidity. • A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting. ENGLISH 8. Heating mode (For cooling and heating models only) The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner, we suggest you use a supplementary heating device. 9.

Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote controller to restart operation. 3. Low noise of the air conditioner • You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing or coming to a stop. • You can also hear a low "squeak" sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing. • A noise may be heard due to louver restoring to its original position when power is first turned on. 4. Dust is blown out from the indoor unit. This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit. 5. A peculiar smell comes out from the indoor unit. This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke. 6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models only) mode. When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to the set point. 7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
