Rapid closure of downstream valves or nozzles during fueling with a high-pressure pump can result in
overpressurization of vessel and cause fuel leaks, leading to possible explosion. Failure to follow this
warning may result in injury or death to personnel.
Water should be drained from the sump daily, or after each fueling operation. See "Post-Operation
Figure 2. Filter/Separator Unit Post-Operation
When fueling operations are complete, shut down pumping system and close upstream and downstream valves to iso-
Open purge valve (figure 2, 1) by turning counter-clockwise.
Place a suitable container under water drain valve (2) and open water drain valve (2) to drain any water that has accu-
mulated in sump.
When all water has drained and green ball in sight gauge (3) reaches bottom, fuel will begin to flow from valve. Close
water drain valve (2).
Dispose of contaminated liquids in accordance with federal and local regulations.
