UMP Replacement Instructions
Replacing the UMP for the Standard STP
14
Figure 8. Verifying Pigtail’s Female Connector Is Seated Properly In Discharge Head
13. Align the UMP positioning dowel and boss with the proper holes in the discharge head and push the UMP
into position using hand force only. The UMP should be snug against the discharge head prior to installing the
UMP retaining bolts.
Use hand force to put the UMP onto the discharge head. If the UMP does not seat
properly, snug against the discharge head, remove the UMP and correct the problem.
14. Install the four new 5/16-18 x 1” UMP retaining bolts and lock washers. Snug and then torque the bolts using
a cross pattern technique. Torque to 7 ft-lb (11 N•m).
Do not use the bolts to pull the UMP into position. Use the cross pattern to snug and
torque bolts. Do not over torque the bolts. Not following these instructions may cause
parts to fail.
Fasteners are not metric - use fasteners provided with equipment.
15. Replace the packer o-ring and discharge Quad seal after lubricating them with petroleum-based jelly.
16. Reinstall the extractable portion into the tank, aligning the positioning dowels of the manifold with the holes in
the packer.
17. Push the packer down as far as possible against the manifold.
18. Insert the lock-down bolts and torque to 45-55 ft-lb (61 to 75 N•m).
19. Loosen the bolts that hold the conduit box to the manifold. Do not remove it.
20. Swing the electrical connector into position.
21. Torque the electrical connector bolt to 25-50 ft-lb (34-68 N•m).
22. Torque the conduit box bolts to 30-45 ft-lb (41 to 61 N•m).
23. If the Functional Element screw was opened in Step 5, check the seating pressure of the adjustable
Functional Element for proper setting.
24. Reconnect the siphon tubing and open the ball valves if these items are used.
