Performing leak tests
LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum and
recirculating the R-410A, it’s responsible of installer to pressurize the whole
system with nitrogen (using a cylinder with pressure reducer) at a pressure
above 40 bar / 580 PSI (gauge).
LEAK TEST WITH R-410A (after the valves have been opened)
Before opening valves, discharge all the nitrogen into the system and create
vacuum. After opening valves check leaks using a leak detector for refrigerant
R-410A.
Once you have completed all the connections, check for possible leaks using
leak detector specically designed for HFC refrigerants.
A(Gas)
B(Liquid)
The designs and shape are subject to
change according to the model.
To check for gas leaks on the Outdoor unit
check the valves on section A and B with a leak detector.
Refrigerant pipe work
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 an insulator around each refrigerant
pipe.
• When insulate the pipe, be sure to overlap the insulation.
NOTE
• When insulating the pipe, use non-slit insulator.
CAUTION
NBR
2. Select the insulation of the refrigerant pipe.
Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
Less than Indoor temperature of 86°F and humidity of 85% is the standard 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 248°F.
