Vertiv Liebert CRV - Leak Checking for Unit and Field-Installed Fluid Piping

6.3.4 Leak Checking for Unit and Field-installed Fluid Piping
The fluid systems in the Liebert CRV are factory-checked for leaks and may be shipped with a nitrogen
holding charge. At installation, check all fluid circuits for leaks.
NOTE: We recommend isolating the unit with field-installed shutoff valves during leak checking of
field-installed piping. When the units are included in a leak test, use of fluid for pressure testing is
recommended. When pressurized gas is used for leak testing the unit, the maximum recommended
pressure is 30 psig (207kPa) and tightness of the unit should be verified by pressure decay over time,
(<2 psig/hour [13.8kPa/hour]) or sensing a tracer gas with suitable instrumentation. Dry seals in fluid
valves and pumps may not hold a high gas pressure.
