Within the temperature range provided in the following table, the air conditioner may stop

running and other anomalies may arise.

x If the temperature is too high, the air conditioner may activate the automatic protection

device. If so, the air conditioner may be shut down.

x If the temperature is too low, the heat exchanger of the air conditioner may freeze, leading

to water leakage or other malfunctions.

x With long-term cooling or dehumidification, at a relative humidity of above 80% (doors and

windows are open), there may be water condensation or dripping near the air outlet.

Conditions that will prevent the unit from running normally

x The fan of the indoor unit will not start running immediately after heating is started, this is to

avoid the blowing out of cool air.

x When it is cold and wet outside, the outdoor unit will develop frost over the heat exchanger

which will compromise the heating capacity. The air conditioner will start to defrost on order

to remedy this condition.

x During defrost, the air conditioner will stop heating for about 5-12 minutes.

x Vapour may arise from the outdoor unit during defrosting. This is not a malfunction and is

normal during the defrosting process.

x Heating will resume after defrosting has completed.
