Vission 20/20 • Operation and Service Manual • Emerson • 35391SC 2.7
READ CAREFULLY BEFORE OPERATING YOUR COMPRESSOR.
The following instructions have been prepared to assist in operation of VilterTM Vission 20/20TM micro-controllers.
The entire manual should be reviewed before attempting to operate.
VilterTM micro-controllers are thoroughly inspected at the factory. However, damage can occur in shipment.
For this reason, the equipment 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 VilterTM representative or the home office should be notified of any claim made.
All inquires should include the VilterTM sales order number, compressor serial and model number. These can be
found on the compressor nameplate on the compressor.
All requests for information, services or parts should be directed to:
