Before You Begin
Prior to backfilling the tank top (i.e. covering the lines, UDC, etc.) the contractor is strongly advised to test all of
the secondary containments for leaks, and to monitor the vacuum during the backfill process. Any leakage
detected must be repaired to prevent future vacuum system alarms.
Do not exceed equipment manufacturer’s recommended vacuum levels
!
While it is common practice to use an independent vacuum source to provide the initial vac-
uum, you must ensure that pump lubricating oil and any other foreign substance is not intro-
duced into the SCVS system. Failure to do so may damage the SCVS system and will void
warranty.
WARNING
This product is to be installed in systems operating near locations where
