In addition to a pressure regulating valve and gauges, always install a pressure relief valve. This can also be a frangible
disc type pressure relief device. This device should have a discharge port of at least 1/2” MPT size. The valve or frangible
disc device must be set to release at 175 PSIG.
• Do not pressurize the system beyond 150 PSIG field leak test pressure. When field testing a system for leaks, 150
PSIG is adequate test pressure.
• Disconnect nitrogen cylinder and evacuate the system before connecting the refrigerant container. Disconnect the
nitrogen cylinder and release the pressure in the system before connecting a refrigerant container to the system.
The higher pressure gas in the system can explode the refrigerant container.
