NOTICE
Vilter compressors are to be installed and connected
to the customer-provided piping. Vilter expects this
piping to be designed and built following ASME B31.3
Process Piping Guide, plus any other local applicable
codes, and that the installation will be performed by
qualifi ed personnel only.
Delivery Inspection
Every equipment supplied by Vilter is thoroughly in-
spected at the factory. However, damage can occur in
shipment. For this reason, the compressor should be
thoroughly inspected upon arrival, prior to off-loading.
Any damage noted should be photographed and report-
ed immediately to the transportation company. This
way, an authorized agent can examine the compres-
sor, determine the extent of damage and take neces-
sary steps to rectify the claim with no serious or costly
delays. At the same time, the local Vilter representa-
tive or the home ofce should be notied of any claims
made within ten (10) days after its discovery. Refer to
Compressor Inspections Prior to Installation for addi-
tional recommendations.
Rigging and Lifting of the Compressor
WARNING
When rigging and lifting a compressor unit, use proper
lifting device capable of lifting and maneuvering the
weight and size of the compressor unit. Use only
qualifi ed personnel and additional personnel and
lifting equipment (i.e. spreader bar) as required.
Failure to comply may result in death, serious injury
and/or damage to equipment.
Only qualied personnel shall operate rigging and lifting
equipment. Ensure that the lifting device is capable of
lifting the weight of the compressor, refer to the sup-
plied Vilter General Assembly (GA) drawing, and to Table
3-1 for weights of bare shaft compressors.
