OPERATION TIPS

Cooling operation
Air conditioners absorb heat from indoor and
transmit the heat to the outdoor unit in order to
decrease the room temperature. The cooling
capacity will increase or decrease according to
the outdoor temperature.
Anti-freezing function
If the unit is in COOL mode and in a low ambient
temperature, frost will be formed on the heat
exchanger of the indoor unit. If the temperature
of the heat exchanger decreases below zero,
the compressor will stop operation to protect
the unit.
Solution
If the defrost mode is started or stopped, you will hear
the sound of refrigerant cooling in the reverse direction.
In HEAT mode, when the temperature of the indoor heat
exchanger is low, the airfl ow is stopped within 2 minutes
in order to prevent cold air.
In HEAT mode, when the outdoor temperature is low
or the outdoor humidity is high, frost will be formed
on the outdoor heat exchanger. The unit will defrost
automatically and the indoor unit will stop blowing air for
3-12 minutes.
In DRY mode, the indoor fan will stop blowing air for
3-12 minutes in order to avoid condensing water being
vaporised again.
In defrost mode, water or vapour may be emitted.
If the unit operates at high humidity for a long time,
moisture will be generated on the grill of the air outlet.
