Referencing Figure 11, pull the UMP end until the distance between the bottom of the manifold and the
bottom of the UMP is 5 inches (125 mm) (15 inches [381 mm] for floating suction) shorter than the distance
measured in Step 2.
If UMP is equipped with floating suction adapter, see section entitled “Recommended
Floating Suction Installation” on page 7.
Figure 11. Adjusting Pump Length
Take care not to damage the pigtail. If pump is to be adjusted shorter, keep tension
on the pigtail to eliminate kinking.
6.
Tighten the column pipe locking nut and torque to 150 ft-lbs (200 N•m) minimum, then torque the set screw in
the locking nut to 30 - 35 in. lb. (3.5 - 4 N•m).
7.
Attach the siphon return line tubing to the barbed fitting in the base of packer and secure with a clamp (see
Figure 12).
Return line should be installed on every application to reduce nuisance trips of electronic
tank monitoring.
