AIR CONDITIONER UNIT OPERATION
Overheating protection (for heat pump unit only)
•
In case the internal temperature and/or the external
temperature are to high, or that the filter is dirty and
clogged out, the refrigerant may be overheated. The
compressor will cut out when the condensing
temperature reaches 62°C.
Frost prevention
•
When the air filter is dirty, the evaporating temperature
will decrease and eventually cause frosting.
•
The LED light will blink to indicate that the filter is
dirty. If the evaporating temperature reaches -2°C, the
unit will trip and defrost.
Fan speed and rated cooling capacity
•
The rated cooling capacity is provided at the maximum
fan speed.
•
The cooling capacity is lower when the unit is operating
at MEDIUM and LOW fan speed.
Dry mode
•
When the air humidity is high, the unit can operate in
dry mode. Press <MODE> button and choose <DRY>.
•
If the room temperature is 2°C higher than the set
temperature, the air conditioner until will operate under
cooling mode until it reaches within 2°C range of
difference compared to the set temperature before it
converts to dry mode.
•
If the room temperature is within 2°C range of
difference compared to the set temperature, it will
directly operate under dry mode.
•
The unit will operate at LOW speed under dry mode.
Heat mode (for heat pump unit only)
•
When the unit is switched on from cold start or
defrosting cycle, the indoor fan will start to operate only
after the coil reaches the desired temperature.
•
When the set temperature is achieved, the indoor fan
will operate until the coil cannot provide anymore
additional heat.
!
Warning
•
Disconnect from the main power supply before servicing the air conditioner unit.
•
DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may result
in fire hazards.
AUTO RANDOM RE-START FUNCTION
If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is
restored. (Applicable only to units with this feature)
!
Caution
Before turning off the power supply, set the remote controller's ON/OFF switch to the “OFF” position to prevent the
nuisance tripping of the unit.
If this is not done, the unit's fans will start turning automatically when power resumes, posing a hazard to service
personnel or the user.
