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.

INSTALLING THE OUTDOOR UNIT  
Checking Correct Earthing  
If the power distribution circuit does not have an earth or the earth  
does not comply with specifications, an earthing electrode must be  
installed. The corresponding accessories are not supplied with the air  
conditioner.

Determine a suitable location for the earthing electrode:  
PVC-insulated green/  
yellow wire, 2mm2 x 3.5 m  
In damp hard soil rather than loose sandy or gravel soil that has a  
higher earthing resistance  
Away from underground structures or facilities, such as gas pipes,  
water pipes, telephone lines and underground cables  
At least 2m(6ft. 7in) away from a lightening conductor earthing  
electrode and its cable

1.6 mm/ 16 ˝, section  
If the earthing wire is too short, connect an extension lead, soldering  
the connection and wrapping it with insulating tape (do not bury the  
soldered connection)  
Secure the earthing wire in position with staples  
If the earthing electrode is installed in an area of heavy traffic,  
its wire must be connected securely.

Carefully check the installation, by measuring the earthing resistance with  
an earthing resistance tester. If the resistance is above the required level,  
drive the earthing electrode deeper into the ground or increase the number  
of earthing electrodes.  
Connect the earthing wire to the earthing screw on the air conditioner.

INSTALLING THE OUTDOOR UNIT  
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).

COMPLETING THE INSTALLATION  
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 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.
