R-410A QUICK REFERENCE GUIDE

Refer to Installation Instructions for specific installation requirements.

•R-410A Refrigerant operates at 50 - 70 percent 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.

•Recovery equipment must be rated for R-410A.

•Do not use R-410A service equipment on R-22 systems. All hoses, gages, recovery cylinders, charging cylinders and recovery equipment must be dedicated for use on R-410A systems only.

•Manifold sets must be at least 700 psig high side, and 180 psig low side, with 550 psig retard.

•All hoses must have a service pressure rating of 800 psig.

•Leak detectors, must be designed to detect HFC refrigerants.

•Systems must be charged with refrigerant. Use a commercial type metering device in the manifold hose.

•R-410A can only be used with POE type oils.

•POE type oils rapidly absorb moisture from the atmosphere.

•Vacuum pumps will not remove moisture from POE type oils.

•Do not use liquid line driers with a rated working pressure rating less than 600 psig.

•Do not install suction line drivers in the liquid line.

•A liquid line drier is required on every unit.

•Do not use an R-22 TXV. If a TXV is to be used, it must be an R-410A TXV.

•Never open system to atmosphere when under vacuum.

•If system must be opened for service, evacuate system then break the vacuum with dry nitrogen and replace filter driers.
