Installation

Each compressor is shipped with printed instruc-
tions for installation. These instructions can also
Each VSH scroll compressor is equipped with two
lift rings on the top shell. Always use both these
rings when lifting the compressor. Use lifting
equipment rated and certified for the weight
of the compressor. A spreader bar rated for the
weight of the compressor is highly recommend-
ed to ensure a better load distribution. The use
of lifting hooks closed with a clasp certified to
lift the weight of the compressor is also highly
recommended. Always respect the appropriate
rules concerning lifting objects of the type and
weight of these compressors. Maintain the com-
pressor in an upright position during all handling
operations.
Never use only one lifting lug to lift the compres-
sor. The compressor is too heavy for the single
lug to handle, and the risk is that the lug could
separate from the compressor with extensive
damage and possible personal injury as a result.
VSH compressors come delivered with four
rubber mounting grommets and metal sleeve
liners that serve to isolate the compressor from
the base frame. These grommets must always be
used to mount the compressor in a single appli-
The required bolt size for the VSH 088 & 117 com-

first and the discharge plug afterwards. The plugs

When the compressor is mounted as part of
an installation, never use the lift rings on the
compressor to lift the installation. The risk is that

contact between the flat washer and the steel

compressor vibrations to the base frame.
