Installing a Pressure Transducer

WARNING
When servicing unit use non-sparking tools and use caution when removing or installing
equipment to avoid generating a spark.

Kits Required:

• Hardware/Seal Kit (P/N 410154-001)

Other parts:

• Pressure transducer (master pump only)

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 36). 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. Turn the service screw counterclockwise as far (up) as possible, (you will hear the check valve drop into place
as the screw nears its up position).
4. Replace the protective plug over the service screw.
5. Remove the 2'' NPT plug or pressure transducer from the pressure transducer port.
6. Install the pressure transducer into the pressure transducer port as per instructions included with device.
7. Turn the service screw counterclockwise all the way up, as the screw approaches its top position, the check
valve will drop into position.
8. Replace the protective plug over the service screw, and fully thread into place to ensure a good seal.
9. Turn the air purge screw 2 - 3 turns counterclockwise (see Figure 36).
WARNING
The air purge screw is retained by a hitch pin to limit travel. Do not attempt to rotate
beyond 3 turns.
10. 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.
11. If applicable, open the ball valve down line from the pump.
Disconnect, lock out, and tag power at the panel before starting to
OFF
service the pump.
