PURONR (R--410A) 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
S Puron refrigerant cylinders are rose colored.
S Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.
S 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
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, 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 W rap 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,andbold text.
S All indoor coils must be installed with a hard shutoff Puron TXV metering device.
