SERVICING WATER SEPARATOR

If the water level in the secondary filter/water coalescer reaches a certain level in the bowl, the water

sensor will trigger the alarm “HIGH WATER ALARM” and shut off the pump. The signal indicates that it is

time to drain the bowl on the secondary filter.

SERVICING SECONDARY FILTER

Clogging filter elements restrict the flow of fuel and the system’s pressure gauge will indicate a pressure

drop.

The gauge and differential pressure indicator are mounted on top of the secondary filter head. At a

differential pressure drop of 25 PSI (red dial area of the gauge) the pump will automatically shut off and

activate the “HIGH PRESSURE ALARM” indicator light. The signal indicates that it is time to change the

filter element.

There are several types of filters available; the STS 7030 30GPM is shipped with a factory installed 10

micron Filter Separator coalescing element.

CHANGING THE SECONDARY FILTERS

See Servicing primary filter instructions above

Note: Disposal of fuel, associated waste and filters should be done in accordance with Federal,

State and Local regulations.

! WARNING ! Some fuels may have been treated with biocides. Biocides are extremely

toxic and may enter the body through the skin. It is recommended to use adequate

protection and proper precautions if fuel contains biocide type products.
