◆ 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.

◆ You have just purchased a split-type room air conditioner and it has

been installed by your installation specialist.

◆ 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.

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 (

or 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.

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.

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.

2 Referring to the illustration opposite, tighten the flare nut first manually

and then with a wrench, applying the following torque.

3 Connect the charging hose of low pressure side of manifold gauge to the

packed valve having a service port as shown at the figure.

4 Open the valve of the low pressure side of manifold gauge

counterclockwise.

5 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.

-

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.

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

position.

7 Mount the valve stem nuts and the service port cap to the valve, and

tighten them at the torque of 18N

•m with a torque wrench.

8 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.

You can install 15m of connecting pipe to the maximum, and you don’t have
to charge any additional refrigerant.

Once you have checked that there are no leaks in the system, you can insulate
the piping, hose and cables and place the indoor unit on the installation plate.

1 To avoid condensation problems, place heat-resistant polyethylene foam

separately around each refrigerant pipe in the lower part of the indoor unit.

2 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

the absorbent pad (make intervals of 20mm / inch).

3 Wind insulating tape around the pipes, assembly cable and drain hose.

4 Place the resulting bundle carefully in the lower part of the indoor unit,

making sure that it does not jut out from the rear of the indoor unit.

5 Hook the indoor unit on to the installation plate and move the unit to the

right and left until you are sure that it is securely in place.
