Operating Recommendations
Here are a few recommendations that you should follow when using your air
conditioner.
Topic
Recommendation
Heating performances
The heat pump function of the air conditioner
absorbs heat from outside air and brings it indoors.
As the temperature of the outside air drops,
the heating performance of air conditioner will decrease.
If you find that the room is not warm enough,
using an additional heating appliance is
recommended.
Frost & Defrost
When outside temperature is low but humidity is high,
frost may form on the outdoor unit at HEAT mode.
If this happens:
The heating operation stops.
T
he defrost mode will be triggered automatically for
about 10 minutes.
he steam produced on the outdoor unit in the defrost
mode is safe. (Only for Heat pump)
T
No intervention is required ; after about ten minutes,
the air conditioner operates again normally.
High indoor and outdoor If both indoor and outdoor temperatures are high
temperatures
and the air conditioner is running at HEAT mode,
the outdoor unit’s fan and compressor may stop
at times. This is normal ; simply wait until the air
conditioner switches on again.
Power failure
If a power failure occurs while the air conditioner is
operating, the unit will be switched off. When the power
returns, the air conditioner starts up again automatically.
The simultaneous
operation
When you use the heat pump model, it is impossible to
operate HEAT and COOL mode of several indoor units at
the same time.
E-10
Temperature and Humidity Ranges
The following table indicates the temperature and humidity ranges, within which the air conditioner can be used.
If the air conditioner is used at...
Then...
High temperature
The automatic protection feature may be triggered and
the air conditioner stopped.
Low temperature
A water leakage or some other malfunction may happen if the heat
exchanger freezes.
High humidity levels
Water may condense on and drip from the surface of the indoor unit if it is
used for a long period.

The standardized temperature for heating is 7°C/45°F. If the outdoor temperature drops to 0°C/32°F or below,
the heating capacity can be reduced depending on the temperature condition.
If the cooling operation is used at over 32°C/90°F(indoor temperature), it does not cool at its full capacity.
