R-410A - General info

This air conditioner adopts the new HFC refrigerant
(R410A) which does not destroy ozone layer.
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 have a dip tube which allows
liquid to flow out with the cylinder in a vertical position
with the valve at the top.
R-410A systems should be charged with liquid
refrigerant. Use a commercial type metering device in the
manifold hose in order to vaporize the liquid refrigerant
before it enters in the unit.
As for other HFC, R-410A refrigerant is only compatible
with oils recommended by the compressor manufacturer.
A vacuum pump is not enough to remove moisture from
oil.
Oils absorb moisture rapidly. Do not expose oil to
atmosphere.
Never open system to atmosphere while it is under
vacuum.
When the system must be opened for service, break
vacuum with dry nitrogen.
Do not vent R-410A into the atmosphere.
Use this unit only for factory approved applications.
The capacity and unit code are stated on the nameplate
data.
