Alternatively: a condensing pressure control valve for each refrigerant
circuit that ensures an average condensing temperature of at least 35
° C .

DIAGRAM WITH CONDENSING PRESSURE CONTROL VALVE

4.8  PRESSURE RELIEF VALVES

Pressure relief valves are fitted on the high pressure side and low pressure side of the refrigerant circuit. The
valves must be vented, to outdoors, through a vent pipe.
The vent pipe must be sized no smaller than the relief valve and it must not be supported from the valve.

Caution: The relief valve must be directed into a safe zone where no
injuries can be caused to people.
