Compressor mounting
Each Danfoss PSH 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 recommended to ensure a better load
distribution. The use of lifting hooks closed
with a clasp and 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 compressor in an
upright position during all handling manoeuvres
(maximum of 15° from vertical).
Never use only one lifting lug to lift the
compressor. The compressor is too heavy for the
single lug to handle, and the risk is run that the
lug could separate from the compressor with
extensive damage and possible personal injury
as a result.
Store the compressor not exposed to rain,
corrosive or flammable atmosphere and between
-31°F and 124°F when charged with R410A and
between -31°F and 158°F when charged whith
nitrogen from factory.
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 run
that the lugs could separate from the compressor
or that the compressor could separate from the
base frame with extensive damage and possible
personal injury as a result.
Never apply force to the terminal box with the
intention of moving the compressor, as the
force placed upon the terminal box can cause
extensive damage to both the box and the
components contained inside.
Maximum inclination from the vertical plane
while operating must not exceed 3 degrees.
Compressors are delivered with pre mounted
rigid spacers dedicated to parallel mounting.
If used in single applications, the compressor
must be mounted with the flexible grommets as
available in accessory conversion kit 8156138.
The grommets must be compressed until contact
between the flat washer and the steel mounting
sleeve is established. The grommets attenuate
to a great extent the transmission of compressor
vibrations to the base frame.
The required bolt size for the PSH051-064-
077 compressors is HM8-55. This bolt must be
tightened to a torque of 15 lbf.ft.
