PRINCIPLE
COOLING MODE
Principle:
The air conditioner absorbs heat from indoor air and transmits it outdoors for discharge, hence to decrease
the indoor ambient temperature. The cooling capacity decreases with the rise of outdoor ambient
temperature.
Anti-freeze Function:
If the air conditioner is running under low-temperature cooling mode, frost will appear on the surface of indoor
heat exchanger. When the temperature of indoor heat exchanger is decreased to 32℉ or below, the
microcomputer of indoor unit will stop the compressor to protect the complete unit.
HEATING MODE
Principle:
The air conditioner absorbs heat from outdoor air and transmits it indoors for emission, hence to increase the
air temperature in the room. The heating capacity decreases with the reduction of the outdoor ambient
temperature.
It takes only a short time for this type of hot air circulating system to increase the indoor temperature.
Use this air conditioner with other heating equipment if the outdoor temperature is extremely low.
Defrost:
When the outdoor temperature is low but the humidity is high, the heat exchanger of outdoor unit may frost
after the air conditioner has run for a period of time. This will decrease the heating effect.
In this case, auto defrost function will be activated and the heating mode will temporarily stop for 8-10
minutes.
Both the indoor fan and outdoor fan will be stopped during auto defrost.
During defrost, the indicator on indoor unit will blink and steam might flow from the indoor unit. This is caused
by the defrost mode.
Heating mode will automatically resume upon completion of defrost process.
Anti-Draft Protection:
If the following conditions are present, the control circuitry in the unit will prevent the indoor fan from
operating:
1. Heat mode (delay 3 minutes).
2. Auto defrost (delay 3 minutes after defrost cycle has completed).
3. If the outdoor ambient temperature falls below 20 ℉, indoor fan will not operate.

16
PRINCIPLE (Cont)
Air Conditioner is Unable to Run Normally
Protection device might be activated within such temperature range as Table 3, so that the unit might be
stopped.
