Frost Prevention of Indoor Unit
When the unit operates at low ambient temperature, frost may appear on the Evaporator. When the indoor coiltemperature is lower than 0C at the end of 10 minutes of continuous compressor operation from the start, themicrocomputer of the unit stops the compressor to protect the unit from the frost. The control procedure forindoor coil freeze protection.
1) The compressor and outdoor fan turn off.2) Indoor fan operates according to user set speed.3) The normal operation returns when the indoor coil
temperature is higher than 7C or equal to 7C.

After the indoor fan is operated for 20 seconds in the Auto Mode the unit will operate automatically by selectingoperating Mode according to the room temperature
(2) Selecting Operating Mode AgainRoom temperature meets desired temperature and the compressor stops running over 30 minutes, then the unitselects operating Mode again.
3 min. Time Delay of Compressor
In normal operation, there is a time delay of three minutes between turn off and turning back on including initialpower up.

NOTE)1) These experiments are processed on the condition of the fixed indoor room TEMP.( DB: 27.0C, WB: 19.0C)2) It takes at least ten minutes for the change of suction pressure to be steady-state, after Air conditioner operates3) To analyze accurately whether refrigerant of Air conditioner leaks or not, you have to check not only suction
pressure but also discharge and suction temperature of compressor4) These data can be changed slightly according to the temperature of environment or each set(Air conditioner)
