4 Be sure that servicing equipment andreplacement 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 themanifold 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.

5 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 beopened for service, break vacuum with dry nitrogenand replace all filter--driers. Evacuateto 500 microns before recharging. Do not vent R--410A into the atmosphere. Do not use capillary tube indoor coils.
