Assembling the hanger screw
Use 2 screws to fix the indoor unit with hanger plate as shown
in the picture.
Screw
• Search for other spots if there are less than two studs, or the distance between the studs are different from the
plate hanger.
• Fix the installation plate without inclining to one side.
• Make sure that a wall can withstand the weight of the product. If you install the product in a place where it is not
strong enough to withstand the product weight, the unit could fall and cause injury.
Performing leak test & insulation
Insulation
Pipes
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 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.
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.
7. Attach the pipe to the wall using clamps (optional).

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.
