Heating mode
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 a large difference between indoor and outdoor temperature. If a comfortable
temperature can't be achieved by the air conditioner, you should use a supplementary heating
device for a short period..
9.
Auto-restart function
Power failure during operation will stop the unit completely.
For units without auto-restart feature, when the power restores, the OPERATION indicator will
flash in the indoor unit. To restart operation, push the ON/OFF button on the remote control.
10.
Lighting or a wireless telephone operating nearby may cause the unit to malfunction. Turn off
the main power then re-start.
