Pre Start-Up
The following check list is to help prepare the equipment before the Vilter technician arrives at the jobsite. Vilter
recommends that a trained technician go through the following tasks. The operating manuals provided by Vilter can
be referenced for any type of questions or special instructions.
Every gas compressor unit includes a Vilter start-up (confirm on P.O.). The following tasks are not included in the
Vilter start-up provided in your equipment purchase. Any tasks below that are done by the Vilter technician will take
away from the pre-determined time that was provided with the equipment purchase. Vilter suggests that the Vilter
technician’s time be used during the start-up of the system and not for the below system preparation.
