WARNING CAUTION

Read through this Installation Manual before installing.

WARNING

Installer must apply for standard installation guidance.

• Please perform the installation work, select insulation, and perform heat insulation construction in accordance with

the laws and regulations of each country.

• For speciﬁcations of connection piping, refer to Table 1 below.

• Piping is limited to newly installed piping.

Even with newly installed piping, remove places to which brazing material is adhered, or which have been burnt the burner.by

• Please keep minimum wall thickness of the pipe for installation.

• Do not disassemble the GAS TIGHT JOINT.

• When rk working in high places, wo must be performed with a stable scaffold.

• Carry out the work of connecting the GAS TIGHT JOINT one location at a time making sure each location is secure.,

(Do not perform simultaneous work on 2 or more locations between the same outdoor and indoor unit)

• Do not use the GAS TIGHT JOINT which has been dropped.

•

The GAS TIGHT JOINT cannot be re-used if it has already been inserted into the piping, temporarily ﬁxed, and removed.

CAUTION

Insufﬁcient insertion

Pipe

Joint main body

Incore

Burr of pipe inside

Check the pipe appearance

Cut the tube to length

The acceptable limit of pipe bend and ality is that pipe can be inserted to the GAS TIGHT JOINT without ov force.

1) If there are scratches, bends, kinks, ovals or thermal aging at the insert part, cut them off.

2) If there are foreign objects, oil, burrs inside and outside of the pipe, remove them.

If connecting pipes are covered with oxide ﬁlms, remove them by a ﬁne sand paper. Do not polish too much.

4) For the piping minimum insertion allowance dimension and the maximum long axis side

dimension for piping which has been slightly ﬂattened, be sure to follow the dimensions in Table 2.

CAUTION

Never scratch pipe sections horizontally, as they may cause refrigerant leakage.

• Cut the pipe slowly to avoid pipe

deformation.

• If the rotary tube cutter is

damaged or dirty, clean it before

use.

Pipe insertion

•

Insertion the pipe straight.

1) Insert ﬁrmly by hand until the pipe stops.

Make sure that the insertion standard line is no longer visible.

Chamfering of the pipe

Marking the insertion standard line

Mark the insertion “T” or “L” standard

line with the marking gauge and

marker pen at proper position of

each pipe size.

1) Outside chamfering / Chamfer about 0.5 C

2) Inside chamfering / Deburr the inner part

•

If no chamfering of the outside of the pipe is performed,

the O-ring would be damaged and cause leakage.

•

Chamfer the inside to ensure a proper refrigerant ﬂow

rate. The



12.7 pipe contains an Incore.

If chamfering of the inside is insufﬁcient, it may cause

improper insertion or damage to the internal struc-

ture, so be sure to carry out chamfering of the inside.

Outside chamfering

Marking method using marking gauge:

GAS TIGHT

JOINT

1) Use a rotary tube cutter.

2) Ensure that the tube is cut square.

3) Check the pipe has retained its shape

and is damage free.

•

Do not tighten the nut before pipe insertion.

•

When inserting the pipe, do not apply excessive force.

The O-ring will be damaged.

•

Do not pull out the tube once it has been inserted.

There is a risk of refrigerant leakage due to damage to

the pipe, damage to the packing or damage to the

incore of



12.7 joint.

•

Carry out chamfering with the pipe pointing

downward, in order to prevent foreign objects from

entering the pipe.

In case any foreign objects enter the pipe, remove them.
