Air conditioner unit opeartion
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 will operate under
cooling mode until it reaches within the 2°C range of
difference compared to the set temperature before it
converts to dry mode.
•
If the room temperature is within the 2°C range of
difference compared to the set temperature, it will
directly operate under dry mode.
•
The indoor fan will operate at super low speed under
dry mood.
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 compressor stops; the indoor fan will operate until
the coil temperature drops to a low level.
Horizontal air flow control
• For more effective air circulation, you can manually
adjust the air discharge grille to the left or right.
• During cool mode operation and dry mode operation,
do not direct the air discharge louver downwards for too
long. If operating continues in this way, condensation
may occur on the louver, thus resulting in drippings.
Overheating protection (for heat pump unit
only)
• In case the internal and/or the external temperature is
too high, or the filter is dirty and clogged up, the
refrigerant may be overheated. The compressor will
reduce its running speed in order to lower the temperature
of heat exchanger. If the temperature is still very high,
the compressor will stop.
Frost prevention
•
When the air filter is dirty, the evaporating
temperature will decrease and eventually cause
frosting.
•
When this happens, the compressor will reduce
its running speed to prevent freezing. If the coil
temperature is still very low, the compressor
will stop.
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 speed.
Turbo function
•
If higher cooling or heating is required
during operation, press "Turbo" button on
the remote control to increase the cooling or
heating capacity to maximum.
•
This function will operate for 15 minutes
before it resume to the actual setting.
•
The fan noise may be higher if the unit
operate in “Turnbo” mode.
