1) Preparation of pipings
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 length of pipe.
2. Remove burrs.
• Remove burrs from cut edges of pipes.
• Turn the pipe end toward down to avoid the metal
powder entering the pipe.
Caution:
If burrs are not removed, they may cause a gas leak-
age.
3. Flaring the pipes.
• Insert the flare nuts, mounted on the connection
ports of both indoor and outdoor unit, onto the cop-
per pipes. Some refrigerant gas may leak, when the
flare nuts are removed from the indoor unit, as
some gas is charged to prevent the inside of the
pipe from rusting.
• Fit the copper pipe end into the Bar of flare tool
about 0.5~1.0mm higher. (See illustration).
• Flare the pipe ends.
4. Tape the flaring portion to protect it from the
dust or damages.

When properly flared, the internal surface flare
will evenly shine and be of even thickness. Since
the flare part comes into contact with the connec-
tors, carefully check the flare finish.
