Maintenance
The system should be visually inspected and tested a minimum of every six (6) months according to the procedure below
during light duty cycles. Monthly inspections are recommended for systems that are being used in excess of an average
of eight (8) hours day and five (5) days a week.
Preventative Maintenance
Prior to performing the maintenance procedure ensure that:
1.
The electrical sub-panel mounted main disconnect switch is operating properly
2.
The user supplied remote circuit breaker is in the “OFF” position
3.
All sources of power are isolated from the unit
Note: Proceed only after this has been verified and properly tagged.
4.
Drain visible water and sediment from primary filter/water separator (see Servicing Primary Filter/Water
Separator)
5.
Check system and all parts for corrosion and rust
6.
Check mounting hardware – tighten as necessary
7.
Check bolts on the pump/motor hardware for tightness, as pump/motor hardware can loosen after normal
operation for extended durations of time, due to vibration.
8.
The hardware uses lock nuts – check all bolts for secure nuts
9.
Check all electrical terminals and connections for tightness
10.
All motors are permanently lubricated and do not require any lubrication
11.
Check all plumbing joints for leaks, tighten fittings and joints as necessary, and remove accumulated fuel in leak-
basin as necessary
12.
Inspect all filter(s) and separator(s)
Note: All filter elements should be replaced at least every six (6) months.
Servicing the Primary Filter/Water Separator
Clogged filter elements restrict the flow of fuel, resulting in the system’s vacuum gauge indicating a pressure drop. The
gauge is mounted between the primary filter and the pump. At a pressure drop of 12” HG, the pump will automatically shut
off and activate the “ALARM LIGHT” indicator. The signal indicates that it is time to either back flush or change the filter
element.
Servicing and back-flushing primary filter:
1.
Press the ‘MANUAL’ button on the System Controller until ‘OFF’ is indicated on the display – making sure the
pump will not turn on
2.
Close the inlet and outlet ball valve
3.
Open the bleed screw at the top of the primary filter cover
4.
Place a fuel waste container below the yellow safety drain valve on the bottom of the filter bowl (unless system is
equipped with optional Automatic Water Drain)
5.
Open the yellow safety drain valve (push & turn counterclockwise)
6.
Close after approximately 2 seconds
7.
After approximately 10 seconds, reopen the drain valve (allows water to settle out of the fuel)
8.
Close after visible sediment, particles, and water have been drained from the bowl
9.
If the filter requires changing, remove the filter from the housing by removing the four bolts that hold the top plate
in place. Remove the spring-loaded cartridge and replace the filter.
10.
Prime the filter by following the instructions found in the Priming section of this manual
11.
Replace the lid. Note: Evenly tighten the bolts to ensure a good seal
12.
Close bleed screw on top of the lid
