The Procedure of Connecting Pipes

CAUTION

All field piping must be provided by a licensed
refrigeration technician and must comply with the
relevant local and national codes.

Do not let air, dust, or other impurities fall in the pipe
system during the time of installation.

The connecting pipe should not be installed until the
indoor and outdoor units have been fixed already.

Keep the connecting pipe dry, and do not let moisture in
during installation.

Execute heat insulation work completely on both sides
of the gas piping and the liquid piping. Otherwise, this
can sometimes result in water leakage.

Drill a hole in the wall (suitable just for the size of the wall

1

conduit), then set on the fittings such as the wall conduit and
its cover.

refrigerant pipe connecting the indoor unit with the outdoor
unit in fluent flow.

6

Check the leakage. Check all the joints with the leak detector
or soap water.

Cover the joints of the connecting pipe with the soundproof /

7

insulating sheath (fittings), and bind it well with the tapes to
prevent leakage.

CAUTION

Be sure to with insulating materials cover all the exposed
parts of the flare pipe joints and refrigerant pipe on the
liquid-side and the gas-side. Ensure that there is no gap
between them.

Bend the tubing in proper way. Do not harm to them.

Bend the pipe with thumb

min-radius 100mm

The bending angle should not exceed 90.

Bending position is preferably in the middle of the
bendable pipe. The larger the bending radius the better it
is.

Do not bend the pipe more than three times.

When connecting the flare nut, coat the flare both inside
and outside with either oil or ester oil and initially tighten
by hand 3 or 4 turns before tighting firmly.

Be sure to use both a spanner and torque wrench
together when connecting or disconnecting pipes to /from
the unit.
