Maintenance and Cleaning
6. The air conditioner turns to Fan Mode from COOL or HEAT (For cooling and heating models only)
Mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to Health mode. The compressor will start again when the
indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to
the set point.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity
(relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and
select HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit
during heating operation. When the outdoor temperature falls, heat drawn in by the air
conditioner decreases accordingly. At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and outdoor temperature. If a
comfortable temperature can't be achieved by the air conditioner, we suggest you use a
supplementary heating device.
