PURONR (R-410A) REFRIGERANT QUICK REFERENCE GUIDE

S 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 refrigerant

S Puron refrigerant cylinders are rose colored.

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

S Puron refrigerant 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

S Manifold sets should be 700 psig high side and 180 psig low side with 550 psig low-side retard. S Use hoses with 700 psig service pressure rating.

S Leak detectors should be designed to detect HFC refrigerant.

S Puron refrigerant, as with other HFCs, is only compatible with POE oils. S Vacuum pumps will not remove moisture from oil.

S Do not use liquid-line filter driers with rated working pressures less than 600 psig. S Do not leave Puron suction line filter driers in line longer than 72 hours.

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

S Do NOT use an R-22 TXV.

S If indoor unit is equipped with an R-22 TXV or piston metering device, it must be changed to a hard shutoff Puron TXV. S Never open system to atmosphere while it is under a vacuum.

S When system must be opened for service, recover refrigerant, evacuate then break vacuum with dry nitrogen and replace filter driers. Evacuate to 500 microns prior to recharging.

S Do not vent Puron refrigerant into the atmosphere. S Do not use capillary tube coils.

S Observe all warnings, cautions, and bold text.

S All indoor coils must be installed with a hard shutoff Puron TXV metering device.
