R-410A SEALED SYSTEM REPAIR CONSIDERATIONS

WARNING

Refrigeration system under high pressure

Do not puncture, heat, expose to fl ame or incinerate.

Only certifi ed refrigeration technicians should service this equipment.

R410A systems operate at higher pressures than R22 equipment. Appropriate safe service and handling practicces must be used.

Only use gauge sets designed for use with R410A.

Do not use standard R22 gauge sets.

The following is a list of important considerations when working with R-410A equipment

•R-410A pressure is approximately 60% higher than R-22 pressure.

•R-410A cylinders must not be allowed to exceed 125 F, they may leak or rupture.

•R-410A must never be pressurized with a mixture of air, it may become

flammable.

•Servicing equipment and components must be specifi cally designed for use with R-410A and dedicated to prevent contamination.

•Manifold sets must be equipped with gauges capable of reading 750 psig (high side) and 200 psig (low side), with a 500-psig low-side retard.

•Gauge hoses must have a minimum 750-psig service pressure rating

•Recovery cylinders must have a minimum service pressure rating of 400 psig, (DOT 4BA400 and DOT BW400 approved cylinders).

•POE (Polyol-Ester) lubricants must be used with R-410A equipment.

•To prevent moisture absorption and lubricant contamination, do not leave the refrigeration system open to the atmosphere longer than 1 hour.

•Weigh-in the refrigerant charge into the high side of the system.

•Introduce liquid refrigerant charge into the high side of the system.

•For low side pressure charging of R-410A, use a charging adaptor.

•Use Friedrich approved R-410A fi lter dryers only.
