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.
