installation
Each Performer® scroll compressor is
delivered with two lift rings. Always
use these rings when lifting the
compressor. A spreader bar rated for
the mass of the compressor is highly
recommended to ensure better load
distribution. Because the compressor's
center of gravity is very high, using only
one lifting lug will result in an unstable
load. The compressor mass is too
great for the single lug to handle, and
there is a risk that the lug could break
off from the compressor resulting
in extensive damage and possible
personal injury. The use of lifting
hooks closed with a clasp and certified
to lift the weight of the compressor is
also highly recommended (see the
adjacent figure).
Always follow the appropriate rules
concerning lifting objects of the type
and weight of these compressors.
When the compressor is mounted as part of an installation, never use the
lift rings on the compressor to lift the
entire installation.
Keep the compressor upright during
all handling maneuvers.
Never apply force to the terminal
box with the intention of moving the
compressor, as the force placed upon
the terminal box will cause extensive
damage to both the box and the motor
protection module component inside.

All compressors are delivered with
four rubber mounting grommets and
metal sleeve liners that serve to isolate
the compressor from the base frame.
To a great extent, these grommets limit
transmission of compressor vibration
to the unit base frame. The rub ber
grommets must be compressed until
contact between the flat washer
and the steel-mounting sleeve is
established.
The required bolt size for the SM / SZ
084 to 185 compressors is HM8. This bolt must be tightened to a torque
of 15.5 ft lb. Bolts and washers are
supplied with the assembly kit.
The required bolt size for the SY /
SZ 240 to 380 compressors is HM10.
The minimum required flat washer
outside diameter is 1.05”. Mounting
bolts must be tightened to a torque of
30 ft lb. These bolts and washers are
not supplied with the compressor.
Note: The large flat washer must be
put in place before shipping a unit
with the compressor installed.
