Temperature and Humidity Ranges
Operating Recommendations
Here are a few recommendations that you should follow when operating 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.
The defrost mode will be triggered automatically for about 10 minutes.
The steam produced on the outdoor unit in the defrost mode is safe.
No intervention is required ; after about 10 minutes, the air conditioner operates
again normally.
High indoor
and outdoor
temperatures
If both indoor and outdoor temperatures are high 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 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 periods.
The standardized temperature for heating is 7°C. If the outdoor temperature drops to 0°C or below,
the heating capacity can be reduced depending on the temperature condition.
If the cooling operation is used at over 32°C(indoor temperature), it does not cool at its full capacity.
