Installation
1. Install the riser pipe into the 4-inch tank opening. Before installing pipe threads, apply an adequate amount of
fresh, UL classified for petroleum, non-setting thread sealant. Tighten the riser pipe in the tank until watertight.
2. Measure the distance from the bottom of the tank to the top of the 4-inch riser pipe as shown in Figure 9.
FOR FIXED-LENGTH PUMPS, SKIP TO Step 7.
3. Uncoil the pigtail at the top of the packer and lay it flat so it will feed into the packer without knotting or
kinking.
4. Loosen the clinch assembly on the column pipe by unscrewing the set screw in the side of locking nut, then
backing off the locking nut (see Figure 10).
NOTICE
A slight twisting of the UMP will loosen the seals and facilitate adjusting it to the correct
length. Do not rotate piping beyond 1/4 turn.
