Preparation of Piping
Main cause of gas leakage is defect in flaring
work. Carry out correct flaring work in the
following procedure.
1) Cut the pipes and the cable.
■ Use the accessory piping kit or the pipes
purchased locally.
■ Measure the distance between the indoor
and the outdoor unit.
■ Cut the pipes a little longer than
measured distance.
■ Cut the cable 1.5m longer than the pipe
length.
2) Burrs removal
■ Completely remove all burrs from the cut
cross section of pipe/tube.
■ Put the end of the copper tube/pipe to
downward direction as you remove burrs
in order to avoid to let burrs drop in the
tubing.
3) Putting nut on
■ Remove flare nuts attached to indoor and
outdoor units, than put them on pipe/tube
having completed burr removal.
(Not possible to put them on after flaring
work)
4) Flaring work
■ Carry out flaring work using flaring tool
as shown below.
Firmly hold copper tube in a bar(or die) as
indicated dimension in the table above.
5) Check
■ Compare the flared work with figure.
■ If flare is noted to be defective, cut off the
flared section and do flaring work again.

Connecting Pipes to the Indoor Unit
6) Pipe bending
Annealed copper pipe with small diameter (ø6.35 or ø9.52) can be easily bent manually. In
this case, secure large R(radius) for the bend section and gradually bend pipe. If annealed
copper pipe is large in diameter (ø15.88 or ø19.05), bend pipe with bender. Use bender
appropriate for the pipe diameter.
7)
Brazing
In refrigerant piping, bending (in particular, acute bending) must be minimized to reduce
piping resistance. Bending is, however, necessary in some places by virtue of the installation
position of devices auxiliary to the packaged air conditioner,or of the building structure,
piping distance or finishing appearance. If a more acute bend is required than that attainable
by pipe bender,perform brazing using ready-made elbow. Aside from this function, brazing
also serves to connect straight pipes, generally using ready-made sockets. While brazing,
protect piping against heat with wet cloth to avoid damaging valve packing or burning
thermal insulator with burner heat. While brazing, blow inert gas (nitrogen gas or carbonic
gas) to prevent formation of oxidation film in copper piping; otherwise, the refrigerant circuit
will clog. The blowing of nitrogen gas (or carbonic gas) through 3-way valves is described in
the following:
8)
Refrigerant piping(Flare piping)
When connecting piping, be sure to keep piping dry(keep piping awayfrom water), clean
(keep piping away from dust) and airtight (avoid refrigerant leakage).
When connecting piping on rainy days or making a through-hole in wall, take due care to
prevent water or plaster from entering piping.
CAUTION: This procedure is
designed to prevent formation of
oxidation film by filling piping with
inert gas. Note that excessive gas
pressure will generate pinholes at
brazed points.
(Nitrogen gas: Supply pressure
0.05~0.1kg/cm2G)
When supplying inert gas, be sure
to open one end of piping.

1) Checking the Drainage
1. Check the drainage.
• Spray one or two glasses of water upon
the evaporator.
• Ensure that water flows drain hose of
indoor unit without any leakage.
1. When piping installation work you
must be used the connector.
2. Align the center of the pipings and
sufficiently tighten the flare nut by
hand
3. Finally, tighten the flare nut with
torque wrench until the wrench
clicks.
■ When tightening the flare nut with torque
wrench, ensure the direction for tightening
follows the arrow on the wrench.
