Section 3 • Installation
Compressor Inspections Prior to
Installation
The compressor must be inspected prior to installation
since components could have come loose and/or dam-
aged during shipment or moving.
• Check for loose bolts, particularly the compressor
mounting nuts.
• Look into the suction and discharge connections and
inspect for any signs of corrosion on parts.
• Check for bent or damaged components. The com-
pressor should have also been inspected prior to off-
loading, see Delivery Inspection.
• Check that the nitrogen pressure is still holding pres-
sure. Any leaks must be fixed and the system purged
and re-charged with dry nitrogen.
• Prelube the compressor with the main oil pump and
rotate by hand several revolutions prior to start.
• Notify Vilter Service and Warranty Department
TM
when the compressor is started.
For Pre Start-Up and Start-Up checklists, please
contact Vilter Service and Warranty Department.
CAUTION
Before installation, follow the proper procedures to
depressurize the compressor.

Compressor Mounting

The Vilter single screw compressor should be firmly
mounted to the package. Isolation dampers should not
be used between the compressor and the package.

stallation details.

Notice on Using Non-Vilter Oils

CAUTION
Do not mix oils. Failure to comply may result in
damage to equipment.
NOTICE
Vilter does not approve non-Vilter oils for use with
Vilter compressors. Use of oils not specifi ed or
supplied by Vilter will void the compressor warranty.
Due to the need for adequate lubrication, Vilter rec-
ommends only the use of Vilter lubricants, designed
specifically for Vilter compressors. With extensive
research that has been performed, we are able to of-
fer per each specific application lubricating oils. Use
of oil not specified or supplied by Vilter will void the
compressor warranty.
Please contact your local Vilter representative or the
Home Office for further information.
