Installation and operation manual

4

The outdoor unit is charged with refrigerant.

Be sure to use both a spanner and torque wrench together when
connecting or disconnecting pipes to/from the unit.

Refer to 

Table 1

 for the dimensions of flare nut spaces and the

appropriate tightening torque. (Overtightening may damage the
flare and cause leaks.)

Table 1

When connecting the flare nut, coat the flare both inside and
outside with ether oil or ester oil and initially tighten by hand 3 or
4 turns before tightening firmly.
Coat here with ether oil or ester oil

Check the pipe connector for gas leaks, then insulate it.

PIPING

 

WORK

Rig the drain piping as shown in the figure and take measures
against condensation. Improperly rigged piping could lead to leaks
and eventually wet furniture and belongings.

1

Install the drain pipes.

-

Keep piping as short as possible and slope it downwards so 
that air may not remain trapped inside the pipe.

-

Keep pipe size equal to or greater than that of the connecting 
pipe (vinyl pipe of 25 mm nominal diameter and 32 mm outer 
diameter).

-

Use the supplied drain hose and metal clamp. Tighten the 
clamp firmly.

Insulate the drain hose inside the building.

If the drain hose cannot be sufficiently set on a slope, fit the
hose with drain raising piping (field supply).

HOW TO PERFORM PIPING 

(See figure 8)

Connect the drain hose to the drain raising pipes, and insulate
them.

Connect the drain hose to the drain pipe on the indoor unit, and
tighten it with the metal clamp.

-

To ensure a downward slope of 1:100, install hanging bars 
every 1 to 1.5 m.

-

If unifying multiple drain pipes, install the pipes as shown in 

figure 9

.

2

After piping work is finished, check if drainage flows smoothly.

-

Open the water inlet lid, add approximately 1 l of water 
gradually and check the drainage flow.
