AIR CONDITIONER WITH PURON

REFRIGERATION SECTION 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.

Puron refrigerant cylinders manufactured prior to March 1, 1999, have a dip tube that allows liquid to flow out of cylinder in
upright position. Cylinders manufactured March 1, 1999 and later DO NOT have a dip tube and MUST be positioned upside down

to allow liquid to flow.

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.

Manifold sets should be 750 psig high side and 200 psig low side with 520 psig low side retard.

Use hoses with 750 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.

Only use factory--specified liquid--line filter driers with rated working pressures no less 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 Puron liquid--line filter drier is required on every unit.

Do not use an R--22 TXV.

Never

open system to atmosphere while it is under a vacuum.

When system must be opened for service, break vacuum with dry nitrogen and replace filter driers.

Do not vent Puron into the atmosphere.

Observe all

warnings, cautions,

and

bold

text.

Do not leave Puron suction line driers in place for more than 72 hrs.
