Refrigerant Piping
Pressure Relief Valves
All units have individual condensers per refrigerant circuit
and each condenser is provided with a spring loaded relief
valve. The valve is set to open when refrigerant pressure
reaches 400 psig. The relief valve will accommodate a 1/2"
flare connection for applications where it is necessary to
connect vent piping and run it outside the building.
CAUTION
When refrigerant is vented to the outside of the
building, install the vent piping as recommended
in ASHRAE Standard 15-1992.
