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

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
refrigerant, break vacuum with dry nitrogen before
opening system.

Always replace filter drier after opening system for
service.

Do not vent Puron

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.
