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 con
-
ditioner 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.
The simultaneous
operation
When you use the heat pump model, it is impossible to oper-
ate HEAT and COOL mode of several indoor units at the same
time.
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.
Common Airconditioner should be used only in the single closed room.
Effective airconditioner operation can be guarantee if all win
-
dows and doors in the room are closed.
