Performing leak test & insulation
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 responsable of installer to pressurize the
whole system with nitrogen (using a cylinder with pressure reducer) at a
pressure above 2 bar, less than 40 bar (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.
The designs and shape are subject to
change according to the model.
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
1
To avoid condensation problems, place Acrylonitrile Butadien Rubber
separately around each refrigerant pipe.
2 Wind insulating tape around the pipes and drain hose avoiding to
compress the insulation too much.
3
Finish wrapping insulating tape around the rest of the pipes leading to the outdoor
unit.
4 The pipes and electrical cables connecting the indoor unit with the
outdoor unit must be xed to the wall with suitable ducts.
5 Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness
according to the pipe size.
Indoor temperature of 30°C and humidity of less than 85% is the stan-
dard condition.
If installing in a high humidity condition, use one grade thicker insulator by
referring to the table below.
If installing in an unfavorable conditions, use thicker one.
Insulator’s heat-resistance temperature should be more than 120°C.

No gap
NBR
CAUTION
• Discharge all the nitrogen to create a vacuum and charge
the system.
CAUTION
• All refrigerant connection must be accessible, in order to
permit either unit maintenance or removing it completely.
NOTE
• Always make the seam of pipes face upwards.
