SERVICING COALESCER
If the water level in the primary filter/water coalescer reaches a certain level in the bowl, the water
sensor will trigger the alarm “HIGH WATER ALARM” and close the solenoid. The signal indicates that it
is time to drain the bowl on the secondary filter.
SERVICING SECONDARY FILTERS
Clogging filter elements and saturation of the water block filters 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
pressure drop of 25 PSI (red dial area of the gauge) the solenoid will close and activate the “HIGH
PRESSURE ALARM” indicator light. The signal indicates that it is time to change the filter elements.
There are several types of AXI International spin on fine filters available; we recommend using the WB-3 (3
micron water block fine filter). The AXI International Water Block incorporates polymer technology to
remove emulsified water from fuel.
CHANGING THE SECONDARY FILTERS:
Note: Both secondary spin on filters need to be replaced at the same time. Always use two of
same type filter elements – never mix two different kinds or micron ratings.
1. Turn key switch to the “OFF” position – make sure pump will not turn on
2. Close the inlet and outlet ball valve
3. Place an appropriate container underneath the filters
4. Remove both old spin on filters with the provided filter wrench by turning the cartridge counter
clock wise seen from the bottom of the cartridge
5. Apply a film of lubricating oil to the gasket of the new filters. Screw the new filter canisters to the
filter head until the gasket is tight and secure (an additional
½
to one turn after the filter makes
contact with the gasket)
6. Open the inlet and outlet ball valve
7. Push the “ALARM RESET” button on the control panel to acknowledge the alarm and reset it
8. Return the pump selector key switch to “AUTO” or “RUN”
9. Check for leaks when re-starting and pressurizing the system
Your system is now ready to resume normal operation
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.
