The operating temperature range (outdoor temperature) is 15°C ~ 24°C.
Tips for energy saving:
(1)
Do not overcool or overheat.
Setting temperature at a moderate level helps energy saving.
(2)
Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors is favourable for cooling (heating).
(3)
Clean air filters once per two weeks.
Clogged air filters lead to inefficient operation and energy waste.
Tips for relative humidity:
(1)
Condensate water is likely to form at the air outlet if cooling or drying for a long time when the relative
humidity is more the 80% (with doors and windows open).
Notices for Use
Cooling Operation
Principle:
(1)
Air conditioners absorb heat in the room and transmit it to the outdoor unit, so that the room temperature
is decreased. The cooling capacity will increase or decrease according to outdoor ambient temperature.
Anti freezing Function:
(2)
If the unit is operating in COOL mode and in low ambient temperature, frost may be formed on the heat
exchanger. When indoor heat exchanger temperature decreased below zero, compressor will stop
operation to protect the unit.
Heating Operation
Principle:
(1)
Air conditioners absorb heat from outdoors and transmit it to the indoor unit, increasing room
temperature. The heating capacity will decrease at low ambient temperature.
Defrosting:
(1)
When the outdoor temperature is low but humidity is high, frost may form on the outdoor unit during
extended operation, affecting heating efficiency. The air conditioner may stop operation during auto
defrosting operation.
(2)
During auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
(3)
During defrosting, the indoor indicator flashes and the outdoor unit may emit vapour. This is not a
malfunction.
(4)
After defrosting is finished, the heating operation will recover automatically.
Anti-cold Air Function
In HEAT mode, the indoor fan will not operate in order to prevent cold air blowing out (within 2 minutes) if
indoor heat exchanger doesn’t reach a certain temperature under the following three states:
(1)
Heating operation starts;
(2)
After Auto Defrosting is finished;
(3)
Heating at low temperature.
Rest Heat Blow
In the following situations, the indoor unit may still run for some time, to blow out the heat remaining in the
indoor unit.
(1)
In HEAT mode, the temperature reached the setting value, the compressor stops and the indoor fan still
run for 60s.
(2)
In HEAT mode, if you turn off the unit, the compressor stops and the indoor fan still runs for 10s.
