Starting the System and Completing the Installation
1. Do not start pumps unless ample product is in the storage tank.
2. Pump sufficient product through each dispenser to purge the entire system of air. If all air is not purged, the
computers may “creep” slightly when the dispenser switch is turned on, but no product has been dispensed.
3. On pumps equipped with built-in siphon, it is necessary to run the submerged pump at least 10 to 20 minutes
continuously to purge the air from the siphon manifold.
4. After the above checks have been made, the backfill can be completed and the manholes installed as shown
