hole (with 65 mm inner diameter) through which the pipe
bundle (consisting of power and communication cables,
refrigerant pipes, and drain hose) will pass and then drill
that hole.

1 Determine the position of a 65 mm hole in

consideration of the possible directions of the pipe
bundle and the minimum distances between the hole
and the installation plate.

CAUTION

• If changing the pipe direction from left to right, do not
drastically bent it but slowly turn it in the opposite
direction as shown. Otherwise, the pipe may be
damaged in the process.

2 Drill the hole.

Step 1.4 Performing leak test

Leak test

LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating
the vacuum and recirculating the R410A, it’s responsible of
installer to pressurize the whole system with nitrogen (using
a pressure regulator) at a pressure above 4.1MPa (gauge).

LEAK TEST WITH R410A (after opening valves)
Before opening valves, discharge all the nitrogen into the
system and create vacuum. After opening valves check
leaks using a leak detector for refrigerant R410A.

Test parts for the

indoor unit

CAUTION

• Discharge all the nitrogen to create a vacuum and
charge the system.

Step 1.5 Wrapping the pipes with the
insulation

After checking for gas leaks in the system, insulate the
pipe, hose and cables. Then place the indoor unit on the
installation plate.

1 To avoid condensation problems, place heat-resistant

poly-ethylene foam separately around each refrigerant
pipe in the lower part of the indoor unit.
