INSTRUCTIONS FOR USE
The Principle and Special Functions of Cooling Mode
Principle:
The air conditioner absorbs heat from indoor air and discharges it
outdoors, thus lowering the indoor room temperature. Cooling
capacity decreases with a rise in outdoor temperatures.
Anti-freeze Function:
Frost may appear on the surface of the indoor heat exchanger if the
air conditioner is running under low-temperature cooling mode.
When the temperature of the indoor heat exchanger drops to 0° or
below the outdoor unit microcomputer will bring the compressor to
a standstill to protect the complete unit.
The Principle and Special Functions of the Heating
Mode
Principle:
• The air conditioner absorbs heat from outdoor air to transmit
indoors thus increasing the room temperature. Heating capacity
decreases with a reduction in outdoor temperatures.
• This type of hot air circulating system can increase indoor
temperatures very quickly.
• Use this air conditioner with other heating equipment when
outdoor temperatures are extremely low.
Defrost:
• The outdoor unit heat exchanger may frost when the outdoor
temperature is low, humidity is high and the air conditioner has
been running for some time, resulting in inefficient heating. In this
case, the appliance automatically defrosts and heating is
suspended for 6/8-10 minutes.
• Both the indoor fan and outdoor fan are brought to a standstill
during auto defrost.
• An indicator light on the indoor unit flashes and mist might flow
from the indoor unit during defrost. This is a result of rapid
defrosting and is quite normal.
• Heating mode is automatically resumed on completion of defrost
process.
Possible causes of failure of the air conditioner to function
A safety device may be activated in the temperature range as
specified below, so that the unit might be stopped.
