Installation Procedure
Step 6 Optional: Cutting and aring the
pipes
1 Make sure that you have the required tools available.
(pipe cutter, reamer, flaring tool, and pipe holder)
2 If you wish to shorten the pipes, cut it with a pipe
cutter, taking care to ensure that the cut edge remains
at a 90° angle with the side of the pipe. Refer to
the illustrations below for examples of edges cut
correctly and incorrectly.

Rough Burr
3 To prevent any gas from leaking out, remove all burrs
at the cut edge of the pipe, using a reamer.
4 Slide a flare nut on to the pipe and modify the flare.

CAUTION
• If the pipes require brazing ensure that OFN(Oxygen
Free Nitrogen) is flowing through the system.
• Nitrogen blowing pressure range is 0.02 to 0.05 MPa.
Step 7 Connecting up and removing air
in the circuit
CAUTION
• When installing, make sure there is no leakage. When
recovering the refrigerant, ground the compressor
first before removing the connection pipe. If the
refrigerant pipe is not properly connected and the
compressor works with the service valve open, the
pipe inhales the air and it makes the pressure inside
of the refrigerant cycle abnormally high. It may cause
explosion and injury.
The air in the indoor unit and in the pipe must be
evacuated. If air remains in the refrigerant pipes, it will
affect the compressor either reduce cooling/heating
capacity or lead to a malfunction. Refrigerant for air
purging is not charged in the outdoor unit. Use Vacuum
Pump as shown at the right figure.
1 Connect each assembly pipe to the appropriate valve
on the outdoor unit and tighten the flare nut.
2 Referring to the illustration below, tighten the flare
nut on section D first manually and then with a
torque wrench, applying the following torque.
