If a siphon system is in place, disconnect the siphon tubing. If ball valves are
installed, close them.
4:
Remove the two lock-down bolts. To relieve pressure, rock the pump to allow excess
pressure to flow into the tank or back out Functional Element screw.
5:
Lift out the extractable unit.
DO NOT damage the surface above the discharge port. The
o-ring below the leak detector port seals on this surface.
Before replacing the extractable portion, make sure that the
packer o-ring and discharge o-ring seal surfaces are clean.
New o-rings should be installed.

EPLACING THE
UMP
ALWAYS DISCONNECT and LOCK or TAG OUT the power
before starting to service the pump.
1: Remove the extractable portion of the old pump from the tank as described in
removing the pump.
2: Remove the old UMP by removing the four bolts holding the discharge head as
shown in figure 4.2.
3: Rock the unit while pulling away from the discharge head until it is free.
4: Replace the old gasket with a new one provided. Place the new gasket on the new
UMP so that all the holes align.
Gaskets from competitive UMPS will not seal properly and
performance will be reduced.
Visually inspect the pigtail connector in the discharge head.
Replace if damaged. Be certain the indexing tab of the
pigtail is seated in the notch of the discharge head
5:
Lubricate o-ring and pigtail with petroleum based jelly.
6:
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.
