Temperature Range Conditions
• 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.
• Heating will resume after the defrost is complete.
Notes for Turning Off Unit
• When the air conditioner is turned off, the main controller will automatically
decide whether to stop immediately or after running for a short period of time
with lower air speed.
