Caution :
If burrs are not removed, they may cause a gas leakage.
3. Flaring the pipes.
• Insert the flare nuts, mounted on the connection
ports of both indoor and outdoor unit, onto the
copper pipes. Some 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.

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
