PIJRON® QUICK REFERENCE GUIDE

FOR INSTALLERS AND TECHNICIANS

• Puron refrigerant operates at 50-70 pel_ent higher pressures thari R-22. Be sure that servicing equipment and

replm:ement components ale designed _o operale x_sith Puron

• Pmon refrigerant cylinders are rose colored.

Recovery cylinder service pressure rating must be 400 psig, D(_F 4BA400 or DO'I Bwq00

Pmon systems should be charged widl liquid refrigeront. Use a commel_ial lype melering device in the manifold hose

Manifold sels should be 750 psig high-side and 200 psig low-side wgh 52g psig low-side retard

Use hoses with 750 psig service pressure rating

Leak delectors should be designed to detect HFC refrigerant

Pmon, as other HFC's, ix only compatible with POE oils

Vacuum pumps will not remove moisture from oil

Do not use liquid-line fiber driers with rated working pressures less than g00 psig

Do not ins_atl a suction-line filter drier in liquid line.

POE oils absorb moisture rapidly Do not expose oil to ammsphere

POE oils may cause d_mage Io certain plastics and roofing malelials

Wrap all fifier dliers and service valves wilh wet cloth when brazing

A liquid-line fil_er drier ix required on every umt.

Do not t_se an R-22 TXV

If indoor unit is equipped wilh an R-22 TXV, it must be changed 1o a Pmon TXV

Never open syslem _o atmosphere while it is t_nder a vacuum

When system must be opened for service, break vacuum with dry nitrogen and replace fifier dliers

Do not vent Pumn into gte almosphere.

Do not use capillary tube indoor coils

Observe all warnings_ cautions and boht lext.
