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 5 metres(16ft 5in) to be respected (15 metres/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 5 metres(16ft 5in) to be respected (15 metres/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 (“B”: indicated in the diagram on the page opposite.) is 3 metres/9ft 10in.

◆ Make sure that the water dripping from the drain hose runs away correctly and safely.

You have just purchased a split-type room air conditioner and it has
been installed by your installation specialist.

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 indoor unit is powered from the outdoor 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
ten metres.

1 Extend the assembly cable if necessary.

2 Open the front grille by pulling on the tabs on the lower right and left sides

of the indoor unit.

3 Remove the screw securing the connector cover.

4 Pass the assembly cable through the rear of the indoor unit and connect

the assembly cable to terminals 1 to 5.

➢ Each wire is labelled with the corresponding terminal number.

5 Pass the other end of the cable through the 65 mm(2 inch) hole in the

wall.

6 Replace the connector cover, carefully tightening the screw.

7 Close the front grille.

8 For further details on how to plug the other end of the assembly cable into

the outdoor unit, refer to page 36.

water is correctly drained outside. When passing the drain hose through the 65 mm(2 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 5 cm/2 inch
between the end of the
hose and the ground.

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)

◆ Underside (C)

◆ Rear

1 With a knife, cut out the appropriate knock-out piece on the rear of the

indoor unit (unless you are connecting directly from the rear).

2 Smooth the cut edges.

3 Remove the protection caps on the pipes and connect the assembly piping

to each pipe, tightening the nuts, first manually and then with a wrench,
applying the following torque.

Pipe Outer Diameter Torque (kg•cm)

Liquid refrigerant 6.35 mm (1/4") 160 (11 ft•lb)

Gas refrigerant 9.52 mm (3/8") 300 (21 ft•lb)
Gas refrigerant 12.70 mm (1/2") 500 (36 ft•lb)

➢

If the piping must be shortened or extended, refer to page 35.

4 Cut off any excess foam insulation.

5 If necessary, bend the pipe round, along the bottom of the indoor unit and

out through the appropriate hole, taking care to ensure that:

◆ The piping does not jut out from the rear of the indoor unit

◆ The bending radius is 100 mm (4 inch) or more

6 Pass the piping through the hole in the wall.

7 For further details on how to connect up to the outdoor unit and purge the

circuit, refer to page 41.

➢ The piping will be insulated and fixed permanently into

position once the whole installation has been tested for

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.

1 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 two metres 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.

3 Dig a hole of the size indicated in the illustration opposite, drive the

earthing electrode into position and cover the top of the electrode with the
excavated soil.

4 Install a green/yellow insulated earthing wire

(

Ø

1.6 mm/ in, section 2 mm

2

/ in2or greater):

◆ 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.

5 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.

6 Connect the earthing wire to the earthing screw on the air conditioner.

NSTALLING 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.

❈ Certainly fix up its rubber leg, in order to prevent its vibration and noise.

Air purging

Refrigerant refill

1 Check the piping connections.
2 Connect the charging hose of low pressure side of manifold gauge to the

packed valve having a service port (3/8” or 1/2” Packed valve) as shown
at the right figure.

3 Open the valve of the low pressure side of manifold gauge counter

clockwise.

4 Purge the air from the system using vacuum pump for about 10 minutes.

- Close the valve of the low pressure side of manifold gauge clockwise.

- Remove the hose of the low pressure side of manifold gauge.

5 Set valve cork of both liquid side and gas side of packed valve to the open

position.

6 Mount the valve stem nuts to the 2-way and 3-way valve.

And mount the service port cap to 3-way valve.

7 Check for gas leakage.

- At this time, especially check for gas leakage from the 3-way valve’s

stem nuts, and from the service port cap.

If connecting pipe of more than 10 metres is installed, additional
refrigerant should be charged by extra metre. You don’t have to
charge additional refrigerant up to 10 metres of connecting pipe.

1 Remove the valve stem cap and service port of 3-way valve.
2 Connect the charging hose of low pressure side of manifold gauge to the

packed valve having a charging port (3/8” or 1/2” Packed valve).

3 Operate the unit at the cooling mode.
4 Slowly open the valve of the low pressure side of manifode gauge counter-

clockwise until the low pressure of manifold gauge indicates 4.8 to 5.5kg/cm

2

(68 to 78 PSI) at the high cool operation (1-unit operation) and the standard
temperature of indoor 26.7°C (80°F) and outdoor 35°C (95°F).
It is recommend that refrigerant should be slowly put in. If the refrigerant is
put in too quickly, compressor will be damaged.

5 Stop operation of the air conditioner.
6 Disconnect the charge hose of manifold gauge.
7 Close the cap of each valve.

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 right figure. Each unit must be purged in turn.
