ENGLISH
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.

The defrost mode will be triggered automatically for
about 10 minutes.
 The steam produced on the outdoor unit in the defrost
mode is safe. (Only for Heat pump)
No intervention is required ; after about ten 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 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-12
Operating Limits
The table that follows provides the operating limits that have to be followed to
ensure a correct operation of the air conditioner.

b.s.: Dry bulb - b.u.: wet bulb;
(1) As per standard UNI EN 14511
(2) Maximum relative humidity: 80% or lower
 The standardized temperature for heating is 44.6°F(7°C). If the outdoor temperature
drops to 32°F(0°C) or below, the heating capacity can be reduced depending on the
temperature condition.
If the cooling operation is used at over 89.6°F(32°C)(indoor temperature), it does not
cool at its full capacity.
 The use of the air conditioner at a relative humidity above the expected one (80%)
may cause the formation of condensate and the leakage of water drops on the floor.
