Operating Recommendations  
Here are a few recom m endations that you should follow w hen 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.

When heating, the required room  
temperature is never reached and  
the air conditioner frequently stops  
Check that the required temperature has been set correctly.  
Increase the fan speed.  
If the air flow is directed downwards, use the remote control to direct it  
upwards.  
The fan speed does not change  
when you press the FAN button  
Check that the operating mode is set to COOL, HEAT or FAN ;  
in the AUTO mode, the fan speed changes automatically and in the

Since this air conditioner is a heat pump model, there can be hollow  
The air conditioner makes a hollow  
sound when it is turned on or off  
sound caused by flow of refrigerant when you turn the air conditioner  
on/off. The sound is not a defect of the air conditioner and it does not  
affect the cooling/heating capacity.

Installing a Filter (Option)  
The air conditioner can be fitted w ith a deodorizing and Bio-Pure  
filter to rem ove m inute dust particles or odours. The service life of  
the filter is approxim ately three m onths depending on the tim e  
during w hich the air conditioner is used.

Remove the vinyl packing from the filter.  
No t e  
Do not remove the packing from a deodorizing filter until you  
wish to use the filter, as it will lose its properties.

PREPARING THE INSTALLATION  
Deciding on Where to Install the Air Conditioner  
When deciding on the location of the air conditioner w ith the ow ner, the follow ing restrictions  
m ust 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 7.5m (24ft. 7in) to be respected (20m(65ft. 7in) 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.  
Install the indoor unit on the wall where the height from the floors more than 2.5 meters(8ft. 3in).  
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 7.5m (24ft. 7in) to be respected (20m(65ft. 7in) 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  
8m (26ft. 3in).  
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 m ust be installed according to the national electrical rules.  
When the outdoor tem perature is below 40°F(4°C), turn the m ain pow er off.

INSTALLING THE INDOOR UNIT  
Purging the Unit  
On delivery, the indoor unit is loaded w ith an inert gas. All this gas  
m ust therefore be purged before connecting the assem bly piping.  
To purge the inert gas, proceed as follow s.  
Unscrew the caps at the end of each pipe.  
Result: All inert gas escapes from the indoor unit.  
To prevent dirt or foreign objects from getting into the pipes  
during installation, do NOT rem ove the caps com pletely  
until you are ready to connect the piping.  
Connecting the Assembly Cable  
The outdoor unit is powered from the indoor unit via the assembly cable.  
If the outdoor unit is more than 5m (16ft. 5in) away from the indoor unit,  
the cable must first be extended to a maximum of 20m (65ft. 7in).

unit.  
Connect the drain hose to the drain plug.  
Drain hole  
Ensure that the drained water runs off correctly and safely.  
Fixing the Unit in Position  
The outdoor unit must be installed on a rigid and stable base to avoid any increase  
in the noise level and vibration, particularly if the outdoor unit is to be installed close  
to a neighbour. If it is to be installed in a location exposed to strong winds or at a  
height, the unit must be fixed to an appropriate support (wall or ground).

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.

Attach the outdoor unit to the appropriate support using anchor bolts.  
Rubber leg  
If the outdoor unit is exposed to strong winds, install shield plates around  
the outdoor unit, so that the fan can operate correctly.  
Certainly fix up its rubber leg, in order to prevent its vibration and noise.

COMPLETING THE INSTALLATION  
Connecting Up and Purging the Circuit  
The outdoor unit is loaded with sufficient R22 refrigerant for 7.5m(24ft. 7in) 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.

Connect each assembly pipe to the appropriate valve on the outdoor unit  
and tighten the flare nut.

Open the valve of the low pressure side of manifold gauge  
counterclockwise.

Close the valve of the low pressure side of manifold gauge clockwise.  
Make sure that pressure gauge show -0.1MPa(-76cmHg) after about  
10minutes.  
This procedure is very important in order to avoid gas leak.  
Turn off the vacuum pump  
Remove the hose of the low pressure side of manifold gauge.

Set valve cork of both liquid side and gas side of packed valve to the open  
position.  
Mount the valve stem nuts and the service port cap to the valve, and  
tighten them at the torque of 18Nm with a torque wrench.

To avoid condensation problems, place heat-resistant polyethylene foam  
separately around each refrigerant pipe in the lower part of the indoor unit.  
Wrap the refrigerant pipes and the drain hose located at the rear of the  
indoor unit up in the absorbent pad.  
Triply wind the pipes and hose to the end of the indoor unit with

Finish wrapping vinyl tape around the rest of the piping leading to the  
outdoor unit.  
Using clamps (optionally supplied), attach the piping to the wall wherever  
possible.
