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 (“L” m/ft. 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 (“L” m/ft. 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
“H”m/ft. (“H”: indicated in the diagram on the page opposite.)
◆ 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

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.
Select an earthing electrode that complies with the specifications given in
the illustration opposite.
2
Determine a suitable location for the earthing electrode:
◆ 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
The earthing wire for the telephone line cannot be used to
earth 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).
1
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.
2
Attach the outdoor unit to the appropriate support using anchor bolts.
3
If the outdoor unit is exposed to strong winds, install shield plates around
the outdoor unit, so that the fan can operate correctly.

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.
1
Connect each assembly pipe to the appropriate valve on the outdoor unit
and tighten the flare nut.
