Operation Range

Operating condition

1
● Temperature ranges suitable for unit operation are as follows.
Cooling
Heating
● When the unit operates above or below these conditions for a long time, system
diagnostics may detect a malfunction and the unit will not operate properly.
● If the unit operates for a long time under abnormal situation of extremely high
==humidity, condensated water may drop from the unit.

Time delay

2
● If the operating mode changes from cooling and dry to heating, there will be
3 minutes time delay between compressor turning off and turning on including
starting the heating operation.
● If the operating mode changes from heating to cooling and dry, there will be 3
minutes time delay.

Minimum operation time

3
● In normal operation, there is a minimum operation time of 5~7minutes between
--compressor turning on and turning off.
Characteristics of heating operation
4
● When heating operation starts, hot air delivery might be delayed due to a warm up period.
● If the outdoor temperature is low, the heating capacity can be degraded. If the
indoor temperature is low in winter, use a auxiliary heater.
Defrost operation (for Heat Pump model)
5
● In the heating mode, when the outdoor coil is frosted, the indoor fan and outdoor fan will
turn off while the compressor will turn on to remove the frost on the outdoor coil.
● Heating operation will resume automatically after removing the frost on the outdoor coil.
Auto recovery operation
6
● When the electricity fails while the unit is operating, the unit memorizes the operating
condition and it will start operation automatically when the electricity is restored.
Frost prevention of indoor unit
7
● When the unit is operates at a low ambient temperature, frost may appear on the indoor
coil. When the indoor coil temperature is below 0℃, the micro computer makes the
compressor stop to protect the unit from frost.
Normal operation
8
● Any of the following can occur during normal operation.
- A sound 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.
- A noise can sometimes be heard during operation or when the unit turns on. It is the
==sound of plastic expanding due to an abrupt temperature change.
