AIR CONDITIONER OPERATIONS AND PERFORMANCE
Check before operation
Turn on switch of the main power supply 12 hours or more before start of the 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 re-starting the air conditioner.
Power failure
Power failure during operation will stop the unit completely.
• To restart the operation, push the START/STOP 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 START/STOP button on the remote controller to restart.
Heating characteristics
Preheating operation
The air conditioner will not deliver warm air immediately after it is turned on.
Warm air will start to flow out after approximately 5 minutes when the indoor heat exchanger warmed up.
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.
Attention to snowfall and freeze on the outdoor unit
• In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up.
If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.
• In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside
for freeze prevention.
If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming.
