Maintenance
If you plan to idle the unit for a long time, perform the following:
1. Operate the fan for about 6 hours to dry the inside of the unit.
2. Stop the air conditioner and disconnect power. If a 4.8kW model is used, interrupt the power supply.
Remove the batteries from the remote controller.
3. The outdoor unit requires periodic maintenance and cleaning. This should only be done by an author-
ized airconditioning engineer.
Checks before operation
Check that the wiring is not broken or disconnected.
Check that the air filter is installed.
Check if the air outlet or inlet is not blocked after the air conditioner has not been used for a long time.
CAUTION
Do not touch the metal parts of the unit when removing the filter. Injuries can occur when
handling sharp metal edges.
Do not use water to clean inside the air conditioner. Exposure to water can destroy the
insulation, leading to possible electric shock.
When cleaning the unit, first make sure that the power and circuit breaker are turned off.
J OPERATION TIPS
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor cannot restart for 3 minutes after it stops.
Anti-cold air
The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one
of the following three situations and the set temperature has not been reached.
A. When heating has just started.
B. Defrosting.
C. Low temperature heating.
Defrosting
The indoor or outdoor fan stops running when defrosting.
Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and
humidity is high resulting in lower heating efficiency of the air conditioner.
During this condition air conditioner will stop heating operation periodically and start defrosting
automatically.
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the
amount of frost buildup on the outdoor unit.
2. A white mist coming out from the indoor unit.
A white mist may generate due to a large temperature difference between air inlet and air outlet on
COOL mode in an indoor environment that has a high relative humidity.
A white mist may generate due to moisture generated from defrosting process when the air condi-
tioner restarts in HEAT mode operation after defrosting.
