Performing Leak Test & Insulation
The designs and shape are subject
to change according to the model.
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.
Leak test
Discharge all the nitrogen to create a vacuum and
charge the system.
CAUTION
1.
Determine the position of the pipe and drain hose hole as
seen in the picture and drill the hole with an inner diameter
of 65mm so that it slants slightly downwards.

Fix the installation plate to the wall giving attention to the
weight of the indoor unit.
If you mount the plate to a concrete wall with anchor
bolts, the anchor bolts must not project more than
20mm.
4.
Determine the positions of the wooden uprights to be
attached to the window frame.
5.
Attach the wooden uprights to the window frame giving
attention to the weight of the indoor unit.
Before fixing the installation plate to the wall or window frame,
you must determine the position of the 65mm hole through
which the cable, pipe and hose pass to connect the indoor unit
to the outdoor unit.
When facing the wall, the pipe and cable can be connected
from the:

1.
To avoid condensation problems, place heat-resistant
polyethylene foam separately around each refrigerant pipe in
the lower part of the indoor unit.
2.
Wrap the refrigerant pipe and the drain hose in the rear of
the indoor unit with the absorbent pad.
Wind the pipe and hose three times to the end of the
indoor unit with the absorbent pad. (20mm interval)
3.
Wind the pipe, assembly cable and drain hose with
insulation tape.
After checking for gas leaks in the system, insulate the
pipe, hose and cables. Then place the indoor unit on the
installation plate.

Attach the installation plate to the wooden uprights using
tapping screws as seen in the picture.
4.
Place the bundle(the pipe, assembly cable and drain hose)
in the lower part of the indoor unit carefully so it doesn’t
project from the rear of the indoor unit.
5.
Hook the indoor unit to the installation plate and move the
unit to the right and left until it is securely in place.
6.
Wrap the rest of the pipe with vinyl tape.
