WARNING
Risk of bursting due to counterfeit refrigerants!
Serious injuries are possible!
Purchase refrigerants only from reputable man-
ufacturers and reliable distributors!
5.1 Maximum allowable pressure
The whole system must be designed and operated
such that the maximum allowable pressure (PS) cannot
be exceeded in any part of the system (see name plate
details).
Pressure relief valves on receivers (pressure vessels)
are absolutely necessary if:
• it is to be expected that the maximum allowable
pressure will be exceeded due to external heat
sources (e.g. fire).
• the entire refrigerant charge of the system is more
than 90% of the pressure vessel volume at 20°C (ca-
pacity). The vessel volume is defined as the volume
between the valves upstream and downstream of a
pressure vessel lockable during normal operation.
• the entire refrigerant charge of the system is more
than 90% of the pressure vessel volume at 20°C (ca-
pacity). The vessel volume is defined as the volume
between the valves upstream and downstream of a
pressure vessel lockable during normal operation.
• a check valve is located between condenser and re-
ceiver.
Safety switching devices
According to local regulations, additional pressure-limit-
ing safety devices must be provided.
