SET UP & USE
OPERATING CONDITIONS
• If the air conditioner is operated outside of the specified temperature ranges, certain safety
protection features may activate, leading to the unit to be disabled.
Cool Mode
Heat Mode
Dry Mode
• 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 dehumidification 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.
NOTE: When the outdoor temperature is below 32°F (0°C) it is recommended to keep the unit
plugged in at all times to ensure smooth ongoing performance.
