AIR CONDITIONER WITH PURON (R-410A) QUICK REFERENCE GUIDE

Puron refrigerant operates at 50-70 percent higher pressures than R-22. Be sure that servicing equipment and replacement components are designed to operate with Puron. Puron refrigerant cylinders are rose colored.

SPuron refrigerant cylinders manufactured prior to March 1, 1999, have a dip tube that allows liquid to flow out of cylinder in upright position.

Cylinders manufactured March 1, 1999 and later DO NOT have a dip tube and MUST be positioned upside down to allow liquid to flow.

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. S Manifold sets should be minimum 700 psig high-side and 180 psig low-side with 550 psig low-side retard.

S Use hoses with minimum 700 psig service pressure rating.

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.

S Only use factory specified liquid-line filter driers with rated working pressures no less than 600 psig. S Do not install a suction-line filter drier in liquid line.

S POE oils absorb moisture rapidly. Do not expose oil to atmosphere. S POE oils may cause damage to certain plastics and roofing materials. S Wrap all filter driers and service valves with wet cloth when brazing. S A Puron liquid-line filter drier is required on every unit.

S Do not use an R-22 TXV.

S Never open system to atmosphere while it is under a vacuum.

S When system must be opened for service, break vacuum with dry nitrogen and replace filter driers. S Always replace filter drier after opening system for service.

S Do not vent Puron into the atmosphere.

S Observe all warnings, cautions, and bold text.

S Do not leave Puron suction line driers in place for more than 72 hrs.
