Purge valve may release a small amount of fuel during venting. Wear protective gear when venting and
place a rag over valve.
Open the air purge valve (1) by turning counter-clockwise.
Start system pump and set to low speed.
Rapid filling of the filter/separator can cause a buildup of static electricity, leading to possible explosion.
Fill filter/separator units slowly to minimize static buildup. Failure to follow this warning may result in
injury or death to personnel.
Recommended flow rates are:
Open external upstream valve slightly to fill vessel slowly.
As vessel fills, observe purge valve (figure 1, 1) and stop filling vessel when purge valve (1) stops venting air.
Close purge valve (1) by turning clockwise.
When vessel is full, check all connections for possible leaks.
10. Open downstream valve or nozzle and adjust pump speed to obtain desired flow rate. See WP 0002 00 for maximum
flow rate for each model of filter/separator.
11. During operation, periodically observe differential pressure gauge (2). If gauge indication reaches red indicator, coa-
lescers should be replaced. See WP 0004 00 for replacement procedures.
12. During operation, samples of filtered fuel can be taken from sampling port (3) using an appropriate sampling device
to determine amount of water in fuel.
13. During operation, periodically observe sight gauge (7). If water level float in sight gauge (7) approaches HIGH mark,
stop operation and open purge valve (1) and water drain valve (6) to empty sump. Refer to steps 1 through 9 and
repeat process for filling vessel.
