PURONR (R-410A) QUICK REFERENCE GUIDE

SPuron 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

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 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, 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 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.
