2.7.9 Refrigerant Piping Protection
The refrigerant in the system(s) is under high-pressure and this pressure can rapidly increase if the
refrigerant is unintentionally conned (or trapped) between isolation devices such as service valves,
liquid line solenoid valves, expansion valves, etc. If the ambient temperature surrounding the piping
system increases, this may cause the contained refrigerant pressure to increase to an unacceptable
level.
WARNING: This increased pressure can cause piping ruptures, discharge of refrigerant,
pollution, equipment damage, injury or death.
Use extreme caution when:
1. Installing the piping lines and make certain that these isolation devices are open
to prevent unintended containment (trapping) of refrigerant.
2. When charging a refrigerant system, do not exceed the Design Pressure
indicated on the unit nameplate.
3. Ensure that pressure has a path to expand when cutting or making connections,
disconnections and piping repairs.
