■

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.

RAIN

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.

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.

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. (See ﬁgure 10)
