Performing Leak Tests - Samsung RJ040F2HX Series Installation Manual

Adding refrigerant A
Important information regulation regarding the refrigerant used
This product contains fluorinated greenhouse gases covered by
the Kyoto Protocol. Do not vent gases into the atmosphere.
CAUTION :
Inform user if system contains 3 kg or more of fluorinated greenhouse gases.
In this case, it has to be checked for leakage at least once every 12 months,
according to regulation n¢X842/2006. This activity has to be covered by
qualified personnel only.
In case situation above (3 kg or more of R-410A), installer (or recognised
person which has responsability for final check) has to provide a
maintenance book, with all the information recorded according to
REGULATION (EC) N¢X 842/2006 OF THE EUROPEAN PARLIAMENT AND OF
THE COUNCIL of 17 May 2006 on certain fluorinated greenhouse gases.
Please fill in with indelible ink,

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 responsable of installer to pressurize the whole system
with nitrogen (using a cylinder with pressure reducer) at a pressure above 30 bar
(gauge).
LEAK TEST WITH R-410A (after opening valves)
Before opening valves, discharge all the nitrogen into the system and create vacuum
according to page 19 ~20.
After opening valves, check leaks using a leak detector for refrigerant.
Then, using a leak detector,check the ...
