part.
Step 2.6 Installing and connecting
the assembly pipes to the refrigerant
pipes (assembly pipe)
Connect indoor and outdoor units with field-supplied
copper pipes by means of flare connections. Use insulated
seamless refrigeration grade pipe only, (Cu DHP type
according to ISO1337), degreased and deoxidized, suitable
for operating pressures of at least 4200 kPa and for burst
pressure of at least 20700 kPa. Under no circumstances
must sanitary type copper pipe be used.

There are 2 refrigerant pipes of different diameters:
• The smaller one is for the liquid refrigerant
• The larger one is for the gas refrigerant
Drain pan outlet A short liquid refrigerant pipe and a short gas refrigerant
pipe are already fitted to the air conditioner. The
Rubber cap
connection procedure for the refrigerant pipes varies
according to the exit position of each pipe when facing
the wall:
Left(A)
1 Cut out the appropriate knock-out piece (A, B, C) on
the rear of the indoor unit unless you connect the pipe
directly from the rear.
2 Smooth the cut edges.
3 Remove the protection caps of the pipes and connect
the assembly pipe to each pipe. Tighten the nuts first
with your hands, and then with a torque wrench,
applying the following torque:
Outer diameter (mm)
ø 6.35
ø 9.52
ø 12.70
ø 15.88
NOTE
• If you want to shorten or extend the pipes, see
Step 2.7 Shortening or extending the refrigerant
pipes (assembly pipe) on page 38.

of the indoor unit. Then pull it out through the
appropriate hole.
• The pipe should not project from the rear of the
indoor unit.
• The bending radius should be 100 mm or more.
6 Pass the pipe through the hole in the wall.
