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.

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.

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.

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).
