This air conditioner is designed
for normal residential use. Do not
use for any other purpose such as
food preservation or drying clothes.
Don't place a space heater or
cooking appliances near the
air conditioner.

Air conditioners absorb heat in the room and transmits it to the outdoor unit, so that
indoor ambient temperatures are decreased. Its cooling capacity will increase or
decrease according to outdoor ambient temperature.
If the unit is running in COOL mode and in low ambient temperature, frost may be
formed on the heat exchanger. When indoor heater exchanger temperature
decreases below zero, the indoor unit microcomputer will stop the compressor
running to protect the unit.
Air conditioners absorb heat from outdoors and transmit it to the indoor unit,
increasing room temperature. Heating capacity will decrease in lower ambient
temperatures.
When outdoor temperature is low but high humidity, frost ma y form on the outdoor
unit during extended operation, affecting heating efficiency. The air conditioner
operation may stop for 8-10mins during auto defrosting function.
During auto defrosting, the indoor indicator flashes and the outdoor unit may
emit vapour. This is not a malfunction.
After defrosting has finished, the heating operation will recover automatically.
In "HEAT" mode, if in the following situations, the operation of indoor unit maybe
delayed until the heat exchanger has achieved a certain temperature.
