Air Cooled liquid chillers
t
This air conditioner adopts HFC refrigerant (R410A) which
does not destroy ozone layer.
t
R-410A refrigerant operates at high pressures. Be sure
that servicing equipment and replacement components
are designed to operate with R-410A.
t
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.
t
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.
t
As for other HFC, R-410A refrigerant is only compatible
with oils recommended by the compressor manufacturer.
t
A vacuum pump is not enough to remove moisture from oil.
t
Oils absorb moisture rapidly. Do not expose oil to atmosphere.
Use this unit only for factory approved applications.
The capacity and unit code are stated on the nameplate data.
