Installation
Installing an Electronic Line Leak Detector Transducer or Mechanical LLD
WARNING
When servicing equipment, use non-sparking tools and use caution when removing or in-
stalling equipment to avoid generating a spark.
Parts Required:
• Electronic or mechanical line leak detector
Procedure:
1. If a ball valve is installed down line from the pump, close it.
2. Remove and save the protective plug over the service screw and turn the screw clockwise (see Figure 22). As
the screw approaches its bottom position, you will hear the system depressurizing. Continue turning the screw
until it can go no further. When the screw is all the way down, back off the screw 4 turns to lift the check valve
and let the fuel drain out of the manifold's hydraulic cavities.
3. Remove the 2'' NPT plug from line leak detector port.
4. Install leak detector into the 2'' NPT port as per instructions included with device.
5. Turn the service screw counterclockwise all the way up. As the screw nears its top position you will hear the
check valve drop into position. Replace the protective plug over the service screw and fully thread into place
to ensure a good seal.
6. Open the air purge screw 2 - 3 turns counterclockwise (see Figure 22).
WARNING
The air purge screw is retained by a hitch pin to limit travel. Do not attempt to rotate
beyond 3 turns.
7. Turn the pump on and let it run for about 2 minutes to purge air from the manifold's hydraulic cavities. While
the pump is still running, turn the air purge screw clockwise until it is completely closed.
8. If applicable, open the ball valve down line from the pump.
OFF
Disconnect, lock out, and tag power at the panel before servicing the
pump.
