When not installing the drain pump

Do not give the hose and upward gradient
after the connection port.
This will cause water to flow backwards when
the unit is stopped, resulting in water leaks.

Do not apply force to the piping on the unit side
when connecting the drain hose. The hose should
not be allowed to hang loose from its connection to
the unit. Fasten the hose to a wall, frame or other
support as close to the unit as possible.

There are two refrigerant pipes of differing diameters:

◆ A smaller one(9.52mm, 3/8

"

) for the liquid refrigerant

◆ A larger one(19.05mm, 3/4

"

) for the gas refrigerant

◆ The thickness of tube should not less than 1.0mm.

◆ The inside of copper tube must be clean & has no dust.

The connection procedure for the refrigerant pipes varies according to
the exit position of the pipes from the indoor unit, as seen when facing
the indoor in the “A” side.

◆ Liquid refrigerant port

◆ Gas refrigerant port

◆ Drain hose connection port

Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque
wrench, a spanner applying the following torque.

Must use insulator which is thick enough to cover the refrigerant tube to
protect the condensate water on the outside of pipe falling onto the floor
and the efficiency of the unit will be better.

Checking Correct Grounding

If the power distribution circuit does not have an earth or the ground does
not comply with specifications, an grounding electrode must be installed.

The corresponding accessories are NOT supplied with the air conditioner.

Select an grounding electrode that complies with the specifications given
in the illustration.

1

Determine a suitable location for the grounding electrode:

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

higher grounding 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 grounding

electrode and its cable

2

Install a green/yellow coloured grounding wire (Ø1.6 mm, section 2 mm

2

or greater):

◆ If the grounding wire is too short, connect an extension lead, in a

mechanical way and wrapping it with insulating tape (do not bury the
connection)

◆ Secure the grounding wire in position with staples

4

Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

3

Carefully check the installation, by measuring the grounding resistance
with a ground resistance tester. If the resistance is above required level,
drive the electrode deeper into the ground or increase the number of
grounding electrodes.

5

Connect the grounding wire to the electrical component box inside of the

Fixing the Unit in Position

E-22

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).

Position the outdoor unit so that the air flow is directed towards the
outside.

1

Attach the outdoor unit to the appropriate support using anchor bolts.

2

If the outdoor unit is exposed to strong winds, install shield plates around
the outdoor unit, so that the fan can operate correctly.

E-23

If you have used...

More than 5 metres
of the pipes

“A”g of refrigerant (R22)
must be added for each
extra metre.

Less than 5 metres
of piping

The purge time is normal

Then...

The outdoor unit is loaded with sufficient R22 refrigerant for 5 metres 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.

Adding Refrigerant
Refrigerant must be added if the piping measures more than 5 metres in

length (maximum of 50 metres). This operation can only be performed by
a qualified refrigeration specialist.

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

1

Referring to the illustration opposite, tighten the flare nut on section B first
manually and then with a wrench, applying the following torque.

2

Connect the charging hose of low pressure side of manifold gauge to the
packed valve having a service port as shown at the figure.

3

Open the valve of the low pressure side of manifold gauge counter­clockwise.

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.
Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
10 minutes.

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.

5

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

6

Mount the valve stem nuts and the service port cap to the valve, and
tighten them at the torque of 183kgf•cm with a torque wrench.

7

Check for gas leakage.

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

stem nuts(A port), and from the service port cap.

When installing, make sure there is no leakage.
When recovering the refrigerant, ground the compressor first before removing
the connection pipe.
If the refrigerant pipe is not properly connected and the compressor works with
the service valve open, the pipe inhales the air and it makes the pressure inside
of the refrigerant cycle abnormally high, It may cause explosion and injury.
