R--410A QUICK REFERENCE GUIDE

• R--410A refrigerant operates at 50% -- 70% higher pressures than R--22. Be sure that servicing equipment and
replacement components are designed to operate with R--410A.

• R--410A refrigerant cylinders are rose colored.

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

• R--410A 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 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.

• R--410A, as with other HFC refrigerants, is only compatible with POE oils.

• Vacuum pumps will not remove moisture from oil.

• Do not use liquid line filter--driers with rated working pressures 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 liquid line filter--drier is required on every unit.

• Do not use with an R--22 TXV.

• If indoor unit is equipped with an R--22 TXV, it must be changed to an R--410A 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 all filter--driers. Evacuate

to 500 microns before recharging.

• Do not vent R--410A into the atmosphere.

• Do not use capillary tube indoor coils.

• Observe all WARNINGS, CAUTIONS, NOTES, and bold text.
