1) Preparation of pipings
1. Cut the pipes and the cable.
•Use the accessory piping kit or the pipes pur-
chased locally.
• Measure the distance between the indoor and the
outdoor unit.
• Cut the pipes a little longer than measured dis-
tance.
• 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
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.
• Fit the copper pipe end into the Bar of flare tool
about 0~1.0mm 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 connectors, carefully check the flare finish.
