Operations and performance

▼ Check before running
• Check whether the earth wire is cut or disconnected.
• Check whether the air fi lter is installed.
• Turn on the circuit breaker 12 hours or more before
starting operation.
▼ 3 minutes protection function
3-minutes protection function prevents the air
conditioner from starting for initial 3 minutes after the
main power switch / circuit breaker is turned on for
restarting the air conditioner.
▼ Power failure
Power failure during operation will stop the unit
completely.
• To restart the operation, push the ON / OFF button
on the remote controller.
• Lightning or a wireless car telephone operating
nearby may cause the unit to malfunction. Turn off
the main power switch or circuit breaker and then
turn them on again. Push the ON / OFF button on the
remote controller to restart.
▼ Defrosting operation
If the outdoor unit is frosted during the heating
operation, defrosting starts automatically (for
approximately 2 to 10 minutes) to maintain the heating
capacity.
• The fans in both indoor and outdoor units will stop
during the defrosting operation.
• During the defrosting operation, the defrosted water
will be drained from the bottom plate of the outdoor
unit.
▼ Heating capacity
In the heating operation, the heat is absorbed from
the outside and brought into the room. This way of
heating is called heat pump system. When the outside
temperature is too low, it is recommended to use
another heating apparatus in combination with the air
conditioner.
