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.

•Recovery cylinder service pressure rating must be 400 psig. DOT 4BA400 or DOT BW400.

•Puron® 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.

•Manifold sets should be at least 700 psig high side and 180 psig low side with 550 psig low-side retard.

•Use hoses with 700 psig service pressure rating.

•Leak detectors should be designed to detect HFC refrigerant.

•Puron® , as with other HFCs, is only compatible with POE oils.

•Vacuum pumps will not remove moisture from oil.

•Do not leave Puron® suction line filter driers in line longer than 72 hrs.

•Do not use liquid-line filter driers with rated working pressures less than 600 psig.

•Do not install a suction-line filter drier in liquid line.

•POE oils absorb moisture rapidly. Do not expose oil to atmosphere.

•Poe oils may cause damage to certain plastics and roofing materials.

•Wrap all filter driers and service valves with wet cloth when brazing.

•A factory-approved liquid-line filter drier is required on every unit.

•Do not use an R-22 TXV.

•If indoor unit is equipped with an R-22 TXV, it must be changed to an Puron® TXV.

•All Puron® Heat Pumps must have indoor Puron® TXV.

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

•When system must be opened for service, recover refrigerant, break vacuum with dry nitrogen prior to opening to atmosphere. Evacuate to 500 microns prior to recharging.

•Always replace filter drier after opening system for service.

•Do not vent Puron® into the atmosphere.

•Do not use capillary tube coils.

•Observe all warnings, cautions, and bold text.
