APPENDIX A — AIR CONDITIONER AND HEAT PUMP WITH PURON – QUICK REFERENCE GUIDE
•Puron
®
(R-410A) refrigerant operates at 50 percent to 70
percent higher pressures than R-22. Be sure that servicing
equipment and replacement components are designed to
operate with Puron refrigerant.
• 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 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.
• Use only factory specified liquid-line filter driers with
rated working pressures greater 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 a 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 refriger-
ant, break vacuum with dry nitrogen before opening
system.
• Always replace filter drier after opening system for service.
• Do not vent Puron refrigerant into the atmosphere.
• Do not use capillary tube coils.
• Observe all warnings, cautions, and bold text.
• All Puron heat pumps must have indoor TXV.
• Do not leave Puron suction line driers in place for more
than 72 hours.
