1. Cut the pipes and the cable.
• Use the accessory piping kit or the pipes purchased
• 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.
• 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
• Turn the pipe end toward down to avoid the metal
powder entering the pipe.
Caution:

age.
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.
