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 units 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 cool as its full capacity.  
E-22  
Cleaning Your Air Conditioner

PREPARING THE INSTALLATION  
Deciding on Where to Install the Air Conditioner  
When deciding on the location of the air conditioner with the owner, the following restrictions  
must be taken into account.  
General  
Do NOT install the air conditioner in a location where it will come into contact with the following elements:  
Combustible gases  
Saline air  
Machine oil  
Sulphide gas  
Special environmental conditions  
If you must install the unit in such conditions, first consult your dealer.  
Indoor Unit  
There must be no obstacles near the air inlet and outlet.  
Install the indoor unit on a surface that can support its weight.  
Choose a position that enables the piping and cables to be easily connected to the outdoor unit and the  
recommended length of 5m (16ft. 5in) to be respected (15m (49ft.3in) maximum).  
Leave enough clearance beneath the indoor unit to enable the filters to be removed without hindrance.  
Maintain sufficient clearance around the indoor unit, as indicated in the diagram on the page opposite.  
Make sure that the water dripping from the drain hose runs away correctly and safely.  
Outdoor Unit  
The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into the  
cooling circuit and seriously damage the unit.  
Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.  
Do not block any passageways or thoroughfares.  
Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any  
neighbours.  
Choose a position that enables the piping and cables to be easily connected to the indoor unit and the recommended  
length of 5m (16ft. 5in) to be respected (15m (49ft.3in) maximum).  
Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary  
noise and vibration.  
Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top of  
the unit.  
Maintain sufficient clearance around the outdoor unit, as indicated in the diagram on the page opposite.  
If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position; the maximum height is  
7m (23ft).  
Make sure that the water dripping from the drain hose runs away correctly and safely.  
CAUTION  
You have just purchased a split-type room air conditioner and it has been  
installed by your installation specialist.  
This device must be installed according to the national electrical rules.  
When the outdoor temperature is below 40°F(4°C), turn the main power off.
