Drill the hole.
CAUTION
• Be sure to drill only one hole.
• Make sure that the hole slants downwards so that the
drain hose slants downwards to drain water well.

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.

• Discharge all the nitrogen to create a vacuum and

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.
2
Wrap the refrigerant pipe and the drain hose in the
rear of the indoor unit with the absorbent pad.
NOTE
• 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.
Installation plate
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.
Attach the pipe to the wall using clamps (optional).
