Leak test
Leak test should be made by pressurizing nitrogen gas to 3.8
MPa(38.7kgf/cm
2
). If the pressure does not drop for 24 hours, the sys-
tem passes the test. If the pressure drops, check where the nitrogen
leaks. For the test method, refer to the following figure. (Make a test
with the service valves closed. Be also sure to pressurize liquid pipe,
gas pipe and high/low pressure common pipe)
The test result can be judged good if the pressure has not be reduced
after leaving for about one day after completion of nitrogen gas pres-
surization.
