APPENDIX A
Air Conditioner & Heat Pump with PURON ®
— Quick Reference Guide
S 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®.
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 Use only factory specified liquid-line filter driers with
rated working pressures greater than 600 psig.
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 a TXV, it must be
changed to a Puron
® TXV.
S Never open system to atmosphere while it is under a
vacuum.
S When system must be opened for service, recover
refrigerant, break vacuum with dry nitrogen before
opening system.
S Always replace filter drier after opening system for
service.
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 Puron ® heat pumps must have indoor TXV.
S Do not leave Puron ® suction line driers in place for
more than 72 hours.
