◆Instructions for Use
Principle and Special Functions during 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°F or below, the microcomputer of indoor
unit will stop the compressor to protect the complete unit. A low ambient kit [not supplied] is required to make unit
operate at lower than 32°F.
Principle and Special Functions under 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 freeze
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 stopped 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 quick defrost other than fault.
＊ Heating mode will automatically resume upon completion of defrost process.
Anti-freeze Function:
Under heating mode, if the indoor heat exchanger fails to reach a specific temperature under the following conditions,
the indoor fan will not be started, so as to avoid blowing of cold air (within 3 minutes):
1. Start of heating mode. 2. End of auto defrost. 3. Heating under low-temperature environment.
★ Conditions that the Air Conditioner will be unable to run normally:
The protection device will be activated within such temperature range as specified below, so that the unit will be shut
down.
