components are designed to operate with Puron
SPuron refrigerant cylinders are rose colored.
SRecovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.
SPuron systems should be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose when charging into suction line with compressor operating
SManifold sets should be minimum 700 psig high side and 180 psig low side with 550 psig
S Leak detectors should be designed to detect HFC refrigerant. S Puron, as with other HFCs, is only compatible with POE oils. S Vacuum pumps will not remove moisture from oil.
