(R--410A) REFRIGERANT QUICK REFERENCE GUIDE

S

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 refrigerant

S

Puron refrigerant cylinders are rose colored.

S

Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.

S

Puron refrigerant 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 refrigerant, as with other HFCs, is only compatible with POE oils.

S

Vacuum pumps will not remove moisture from oil.

S

Do not use liquid--line filter driers with rated working pressures less than 600 psig.

S

Do not leave Puron suction line filter driers in line longer than 72 hours.

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 an R--22 TXV or piston metering device, it must be changed to a hard shutoff balanced port Puron TXV.

S

Never open system to atmosphere while it is under a vacuum.

S

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

Evacuate to 500 microns prior to recharging.

S

Do not vent Puron refrigerant into the atmosphere.

S

Do not use capillary tube coils.

S

Observe all

warnings

,

cautions

, and

bold

text.

S

All indoor coils must be installed with a hard shutoff balanced port Puron TXV metering device.
