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.
•
Do not turn the nut in the loosening direction.

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.
3)
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
6
•
Insertion the pipe straight.
1) Insert firmly by hand until the pipe stops.
2)
Make sure that the insertion standard line is no longer visible.
Chamfering of the pipe
Marking the insertion standard line
5
4
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.

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.
Monkey wrench
Complete tightening
the nut until the green
indicator disappears.

Main body
WARNING
CAUTION
Checking
Tightening of nut 98
Hold the main body and tighten the nut with a monkey
wrench to the direction of arrow until the green indicator
disappears and the nut comes into contact with the flat face
of the body.
• In case of insufficient nut tightening,
it may cause pipes to come off.
• Excessive tightening prohibited.
It may cause joint damage or stress
corrosion cracking.
Tighten the nut completely using the
same level of torque as the level which
is sufficient to overcome the pawls.
• Before using the tools, be sure you
understand how to use them correctly.
• Do not turn the nut in the loosening
direction.
• Do not tighten the joint main body.
1) Green indicator should be hidden.
2) Place the marking gauge on the end face of the nut and make sure that
the “T” or “L” shaped mark falls completely within the notch in the
marking gauge.
The marking gauge contains one notch for measuring the insertion of
pipe of 28 or less, and another notch for measuring the insertion of
pipe of 31 or more. Be sure you are using the correct notch when
measuring.
If the “T” or “L” shaped mark falls outside the notch in the marking gauge,
cut off the joint, replace it with a new joint, and carry out construction
again.
Manual tightening of nut
7
Hold the main body and tighten the nut in the
direction of the arrow hand until it will not turn by
anymore.
Cautions after construction
10
[Example of work that requires caution]
1) If connecting REFNET joints
• After tightening, do not rotate the joint excessively.
• Do not apply excessive twisting forces to the GAS TIGHT JOINT after connection.
• First, connect the GAS TIGHT JOINT to the joint, adjust the orientation of the
joint, then carry out connection to the pipe.
Green indicator
* Install the joint so that it branches
on a horizontal plane.
• If connection of the joint is carried out after connection with the pipe, when the GAS TIGHT JOINT is tightened,
the joint will turn along with it, so it may be difficult to construct on a horizontal plane.
• Before insulating, check according to step Checking.
