CARE AND MAINTENANCE
Frost Prevention of Indoor Unit
When the unit operates (on cooling) at a low ambient temperature, frost may appear on the indoor coil. When the
indoor coil temperature is below 0°c, the microcomputer makes the compressor stop to protect the unit from frost.
Normal Operation
Any of the following can occur during normal operation:
• A sound like a "GURGLE" can sometimes be heard during operation or when the unit stops.
- It is the sound of the refrigerant flowing through the unit.
• Bad smells can come from the unit.
- Smells such as smoke or cosmetics can accumulate while room air circulates through the unit.
- Cleaning the filters will reduce this problem.
• The outdoor fan does not rotate during heating operation.
- The unit is in defrost mode.
• UNIT ON lamp on the indoor unit display flashes and no air comes from the unit.
- It indicates malfunction of the unit and the compressor will stop operating.
• A "creaking" noise can sometimes be heard during operation or when the unit turns on.
- This is the sound of plastic expanding due to an abrupt temperature change.
