OPERATING INSTRUCTION MANUAL
400 SERIES COMPRESSORS
READ CAREFULLY BEFORE INSTALLING AND STARTING YOUR COMPRESSOR.
The entire manual should be reviewed before attempting to install, service or repair the compressor.
A refrigeration compressor is a positive displacement machine. It is designed to pump superheated
vapor. The compressor must not be subjected to liquid carry over. Care must be exercised in properly
designing and maintaining the system to prevent conditions that could lead to liquid carry over. Vilter
Manufacturing Corporation is not responsible for the system or the controls needed to prevent liquid
carry over and as such Vilter Manufacturing Corporation cannot warrant equipment damaged by im-
properly protected or operating systems.
Vilter screw compressor components are thoroughly inspected at the factory, assuring the shipment of a
mechanically perfect piece of equipment. Damage can occur in shipment, however. For this reason, the
units should be thoroughly inspected upon arrival. Any damage noted should be reported immediately to
the Transportation Company. This way, an authorized agent can examine the unit, determine the extent
of damage and take necessary steps to rectify the claim with no serious or costly delays. At the same
time, the local Vilter representative or the home office should be notified of any claim made.
