18. CONNECTING REFRIGERANT PIPING LINES
18-1 R410A – Quick Reference Guide
(1) R410A refrigerant is a substance that is not depleting the zone layer.
(2) R410A refrigerant operates at 50% - 70% higher pressure than R22.
(3) Be sure that installation, service and maintenance equipment are designed
to operate with R410A refrigerant.
(4) Be sure that replacement components are designed to operate with R410A
refrigerant.
(5) R410A refrigerant cylinder is Rose color.
(6) R410A refrigerant cylinder has a dip tube which allows liquid to flow of
cylinder in an upright position.
(7) R410A refrigerant is only compatible with oils selected by the compressor
manufacturer.
(8) Never expose oil to atmosphere because POE oils absorb moisture rapidly.
(9) Never open the system to atmosphere while it is under vacuum.
Filter drier is recommended to be used at installation site.
(10) Do not vent R410A refrigerant into the atmosphere.
Use only approved recovery equipment for R410A refrigerant.
Do not use recovery equipment for R22 Refrigerant.
(11) In case of service and maintenance, R410A system should be charged with
refrigerant R410A in liquid phase.
Use a commercial type metering device in the manifold hose in order to
vaporize the liquid refrigerant before it enters in the system.
