Operating Instructions
Cooling Mode = Principle and Special Functions
Principle of Operation
The air conditioner absorbs heat from the air and discharges it to the oudoors, thereby cooling the indoor ambient tempera-
ture. Cooling capacity decreases with the increase of the outdoor temperature.
Special Anti-freeze Function
If the air conditioner is operating under low-temperature conditions in the cooling mode, frost will appear on the surface of
the indoor heat exchanger. As the temperature of the heat exchanger decreases to 0°F or less, the microcomputer in the
indoor unit will stop the compressor operation in order to protect the unit.
Principle of Operation
The air conditioner absorbs heat from the outdoor air bringing it indoors to heat the space, thereby increasing the indoor
ambient temperature. Heating capacity decreases with the reduction of the outdoor temperature.
With this type of hot air circulation system, the indoor temperature increases rapidly.
Use this air conditioner with other heating equipment if the outdoor temperature es extremely low.
Special Defrost Function
When the outdoor temperature is low but the humidity is high, the heat exchanger in the outdoor unit may frost up after a
certain period of operation, thus decreasing the heating effect in the room. When this occurs, the defrost cycle is automati-
cally activated, temporarily halting the heating mode function for a period of 8 to 10 minutes.
Both the indoor fan and outdoor fan will be stopped during the defrost cycle.
During the defrost cycle, the indicator on the indoor unit will blink and in some cases you may notice steam flowing from the
indoor unit. This is caused by the quick defrost cycle.
Heating mode will automatically resume its operation upon completion of the defrost cycle.
Heating Mode = Principle and Special Functions
Special Anti-cold-air Function
When in the heating mode, if the indoor heat exchanger fails to reach a specific temperature degree in the following 3 instances, the
indoor fan will not be started thereby avoiding to blow cold air into the space (within 3 minutes):
1) Start of heating mode; 2) End of auto defrost; 3) Heating under low ambient temperature
Conditions that Inhibit the Unit from Operating Normally
Under temperature ranges as specified below, a protection device may be activated which will stop the unit from operating.
Outdoor temperature
over 24°C Outdoor temperature Room
over 43°C temperature
Heating Outdoor temperature Cooling Dehumidifying below 18°C
Mode below -7°C Mode Mode
Room temperature Room temperature
over 27°C below 21°C
If the unit is run for long periods in cooling or dehumidifying modes when the relative humidity is higher than 80% (doors and
windows are open), condensing may occur near the air outlet.
