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
been installed by your installation specialist.
◆ This device must be installed according to the national electrical rules.

INSTALLING THE INDOOR UNIT
Purging the Unit
On delivery, the indoor unit is loaded with an inert gas. All this gas
must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
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 remove the caps completely
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 five metres away from the indoor unit, the
cable must first be extended to a maximum of “L”m/ft.
1
2
Extend the assembly cable if necessary.
Open the front grille by pulling on the tabs on the lower right and left sides of
the indoor unit; if necessary, refer to page 21.
◆◆The designs and shape are subject to
change according to the model.

INSTALLING THE INDOOR UNIT
Installing and Connecting the Indoor Unit Drain Hose
Care must be taken when installing the drain hose for the indoor unit to ensure that any
condensation water is correctly drained outside. When passing the drain hose through
9
the 65mm(
inch) hole drilled in the wall, check that none of the following situations occur.

The hose must
NOT slope
upwards.
The end of the drain
hose must NOT be
placed in water.
Do NOT bend the
hose in different
directions.
Keep a clearance of at
least 5cm(2inch)
between the end of the
hose and the ground.
Do NOT place the
end of the drain hose
in a hollow.
To install the drain hose, proceed as follows.

Pass the drain hose under the refrigerant piping, taking care to keep the
drain hose tight.
Pass the drain hose through the hole in the wall, making sure that it is
sloping downwards, as shown in the illustrations above.

INSTALLING THE INDOOR UNIT
Installing and Connecting the Indoor Unit Assembly Piping
There are two refrigerant pipes of different diameters:
◆ A smaller one for the liquid refrigerant
◆ A larger one for the gas refrigerant
A short length of piping is already fitted to the air conditioner. You
must extend this piping using assembly piping (optionally supplied).
The connection procedure for the refrigerant piping varies according
to the exit position of the piping from the indoor unit, as seen when
facing the air conditioner in position on the wall:
◆ Right (A)
◆ Left (B)

INSTALLING THE INDOOR UNIT
Cutting/Extending the Piping
Five metres(16ft 5in) of piping is supplied with the air
conditioner(Optional). This length can if necessary be:
◆ Extended to a maximum of “L” m/ft.
◆ Shortened as required
◆
If more than 5m(16ft 5in) of piping is required:
◆ The assembly cable must also be extended
◆ Refrigerant must be added to the circuit by an
approved installer; otherwise, the indoor unit may
freeze

Make sure that you have the required tools available
(pipe cutter, reamer, flaring tool and pipe holder).
If you wish to shorten the piping, cut it using a pipe cutter, taking care to
ensure that the cut edge remains at a 90° angle with the side of the pipe,
and referring to the illustrations below for examples of edges cut correctly
and incorrectly.

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.

◆
In damp hard soil rather than loose sandy or gravel soil that has a
higher earthing resistance

with the excavated soil.
1
Install a green/yellow insulated earthing wire (
2 mm2 or greater):
Ø
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.
◆◆The designs and shape are subject to
change according to the model.
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.
1
Connect each assembly pipe to the appropriate valve on the outdoor unit
and tighten the flare nut.
