Operating Recommendations
Here are a few recommendations that you should follow when using
your air conditioner.
Topic
Recommendation
Heating performances
The heat pump inside the air conditioner
absorbs heat from outside air and brings it
indoors. If the temperature of the outside air
drops, the air conditioner will heat less. If you
find that the room is not warm enough, use an
additional heating appliance.
Warm air circulation
The air conditioner circulates warm air to heat
your room; as a result, some time will be
required after starting the air conditioner to
warm the entire room. If necessary, set the air
conditioner on before you wish to use the
room.
Frost
When outside temperatures are low and
humidity is high, frost may form in the outdoor
unit when heating is selected.
If this happens:
◆ The heating operation is stopped.
◆ The Deice mode is triggered automatically
for about seven minutes.
No intervention is required from you; after
about seven minutes, the air conditioner starts
operating again normally.
High indoor and outdoor If both the indoor and outdoor temperatures
temperatures
are high and you select the 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 when the air
conditioner is operating, the unit is switched off.
When the power returns, you must press the
(ON/OFF) button to restart it.
E-21
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 temperatures
The automatic protection feature may
be triggered and the air conditioner
stopped.
Low temperatures
A water leak or some other malfunction
may occur 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 long periods.

then, it does not heat as its full capacity.
If the cooling operation is used at over 92°F/33°C(indoor temperature)
then, it does not cool as its full capacity.
E-22

INSTALLING THE OUTDOOR UNIT
Connecting Up and Purging the Circuit
The outdoor unit is loaded with sufficient R22 refrigerant for 5m(16ft. 5in) of
piping. The air in the indoor unit and in the pipe must be purged.
If air remains in the refrigeration pipes, it will affect the compressor,
reduce to cooling/heating capacity and could lead to a malfunction.
Refrigerant for air purging is not charged in the outdoor unit.
Use Vacuum Pump as shown at the figure.
