SAFETY INFORMATION
OPERATING CONDITIONS
• Within the temperature range provided in following table, the air
conditioner may stop running and other anomalies may arise.
• When the temperature is too high, the air conditioner may activate the
automatic protection device, so that the air conditioner could be shut
down.
• When the temperature is too low, the heat exchanger of the air
conditioner may freeze, leading to water leakage or other malfunction.
• In long-term cooling or dehumidication with a relative humidity
of above 80% (doors and windows are open), there may be water
condensation or dripping near the air outlet.
NOTES FOR HEATING
• The fan of the indoor unit will not start running immediately after the heating is
started to avoid blowing out cool 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 fast defrost.
• Heating will resume after defrost is complete.
