PURON®— 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 4BW400.

•Puron® systems should be charged with liquid refrigerant only. Use a commercial type metering device in the manifold hose when charging into suction line with compressor operating.

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

•Use hoses with minimum 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.

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

•Vacuum pumps will not remove moisture from oil.

•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.

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

•A factory apporved liquid-line filter drier is required on every Puron® unit.

•Do NOT use an R-22 TXV.

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

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

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

•Do not vent Puron® into the atmosphere.

•Do not use on capillary coils.

•Observe all warnings, cautions, and bold text.
