CAUTION
NOTE:
•This product contains fluorinated greenhouse gases. Never try to interfere with the
refrigerant circuit yourself or disassemble the product yourself and always ask a
professional. The specification of the fuse is printed on the circuit board, such as:
3.15A/250V AC, etc. Refrigerant leakage contributes to climate change. Refrigerant with
lower global warming potential (GWP) would contribute less to global warming than a
refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a
refrigerant fluid with a GWP equal to [2088]. This means that if 1 kg of this refrigerant fluid
would be leaked to the atmosphere, the impact on global warming would be [2088] times
higher than 1 kg of CO2 , over a period of 100 years.
1. Do not open windows and doors for a long time when the air conditioner is running. This will cause
the cooling or heating capacity to be weakened.
2. Do not stand /sit on top of the outdoor unit and do not place heavy items on it.
3. Do not apply cold air from the unit to the body for a prolonged time.
4. It is recommended that the temperature difference between indoor and outdoor temperature should
not be too large. Appropriate adjustments of the setting temperature can prevent the waste of
electricity.
5. If your air conditioner is not fitted with a supply cord and a plug, an all-pole switch must be installed
in the fixed wiring and the distance between contacts should be no less than 0.1 inch.
6. If your air conditioner is permanently connected to the fixed wiring, a residual current device (RCD)
having rated residual operating current not exceeding 30 mA should be installed in the fixed wiring.
7. The power supply circuit should have leakage protector and air switch of which the capacity should be
more than 1.5 times of the maximum current.

•Outside the temperature range provided in following table, the air conditioner
may shut down.
•When the temperature is too high, the air conditioner may activate the automatic
protection device and shut the unit down.
•When the temperature is too low, the heat exchanger may freeze, leading to
water leakage or another malfunction.
•In long-term cooling or dehumidification with a relative humidity of above 80%
(doors and windows are open), there may be water condensation near the air
outlet.
Notes for Heating
•The fan of the indoor unit will not run immediately after cooling to prevent
expelling cold air.
•When it is cold and wet outside, the outdoor unit will develop frost over the heat
exchanger which will compromise the heating capacity. This is when the air
conditioner will start to defrost.
•During defrost, the air conditioner will stop heating for about 5-12 minutes.
•Vapor may come out from the outdoor unit during defrost. This is not a
malfunction, but a result of a fast defrost.
