Carrier ROOM AIR CONDITIONER User Manual page 31

4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first
use of the unit.
5. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture,
or smoke.
6. The air conditioner turns to FAN only 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 FAN only 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.
9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor
unit starts flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit
with Auto-restart feature, when the power restores, the unit restarts automatically with all the previous settings
preserved by the memory function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on
the remote controller to restart operation.
