Mounting Parts
Caution
To minimize vibration and start/stop impulses, fl exible
mountings should be used. Because Copeland Scroll™
Fusion has scroll hermetic compressor level of vibration,
grommets are delivered. A compressor may be rigidly
mounted (i.e. without grommet) - in which case, more
shock and vibration will be transmitted to the frame.
To ensure proper lubrication of moving parts, the
compressor should be installed with four mountings in the
same plane.

Delivery
Please check carefully for unforeseen damage. Any
shortage or damage should be reported to the delivering
carrier. Heavy equipment should be left on its shipping
base until it is moved to the fi nal location.
The packing list included with each shipment should be
carefully checked to determine if all parts and equipment
have been received. Defi ciencies should be immediately
reported in writing to your local Emerson Sales Offi ce.

Packaging
All compressors are individually packed. Accessories may
be mounted or delivered loose. Please pay attention to
stacking layers. Stacking in transit should not be more
than two layers and stacking in-store should not be
more than three layers. The packaging must be kept dry
and without damage at all times.
Transport
Compressors should be moved only with mechanical
handling equipment appropriate for the weight
involved. For safety reasons, one lifting eye should be
fi tted before moving a compressor (M16x2.0). Please
refer to the illustrations on Figure 3 to see how to lift the
compressor safely.
The compressors must not be lifted by the service valves
or other accessories. Otherwise damage or refrigerant
leaks may occur.

Warning
The compressor is supplied with an initial oil charge.
Mineral oils are approved for R22 application, and Karamay
32BYMO is fi lled ex-factory. The standard oil charge for use
with R404A is a polyester (POE) lubricant Emkarate RL 32-
3MAF. In the fi eld, the oil level could be topped up with
Mobile EAL Arctic 22 CC if 3MAF is not available.
Do not mix ester oils with mineral oil and/or alkyl
benzene when using chlorine-free (HFC) refrigerants. See
nameplate for original oil charge in litres. A fi eld recharge
is from 50-100 ml less than the original charge.
Oil must be drained from both the high and low sides of
the compressor whenever oil is changed.
One disadvantage of POE is that it is far more hygroscopic than
mineral oil (see Figure 2). Brief exposure to ambient air causes
POE to absorb suffi cient moisture to make it unfi t for use in a
refrigeration system. Since POE holds moisture more readily
than mineral oil, it is more diffi cult to remove it through the
use of a vacuum. Compressors supplied by Emerson Climate
Technologies contain oil with low moisture content, and
this may rise during the system assembling process. POE oil
should not be exposed to the atmosphere for longer than 15
minutes. A fi lter drier is installed to help maintain moisture
level in the oil less than 50 ppm. If oil is charged into a system,
it is recommended to use POE with a moisture content no
higher than 50 ppm.
Maximum Operating Pressures
A high-pressure control with a maximum cut-out
setting of 28 bar(g) is required.
The high-pressure cut-
out should have a manual reset feature for the highest
level of system protection.
The low-pressure cut-out should be set as high as possible in
all applications. For medium temperature applications, the
normal minimum is 2.5 bar(g) which corresponds to -10
o
C
for R22 and -16
o
C for R404A.
For low temperature applications the minimum cut-out
setting should not be lower than 0.3 bar(g) for a compressor
using R404A, and should not be lower than 0.1 bar(g) for a
compressor using R22. The cut-out point of the LP switch
must be calibrated using an accurate suction pressure gauge
rather than the scale on the switch which is provided for rough
setting only.
The Copeland Scroll™ Fusion compressor should
NEVER be allowed to run in a vacuum. The low-
pressure cut-out should have a manual reset feature
for the highest level of system protection.
The maximum pressure for leak testing should be no
higher than 22.5 bar(g).
Approved Refrigerants and Oil
Refrigerants R404A and R22 are approved for use with
Copeland Scroll Fusion. Application with other refrigerants
may be possible in special cases. Please contact an Emerson
Climate Technologies Application Engineer.
