Installing the Pump
• The Red Jacket STP is designed to operate in a Class 1, Group D atmosphere and in accordance with
CENELEC standard EN 15268 and the European Directive 2014/34/EU “Equipment for Potentially
Explosive Atmospheres” (Ex II 1/2 G IIA T3).
• The manufacturer may recommend new specification and installation instructions.
• The product temperature must not exceed 105°F (41°C) because the thermal overload protectors in the
submersible motor may trip.
1.
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 8.
Note: For fixed-length pumps, referencing Figure 10, verify the distance between the bottom of the manifold
and the bottom of the UMP is 5 inches (125mm)(15 inches [381mm] for floating suction) shorter than the dis-
tance measured in Step 2. Uncoil the pigtail at the top of the packer. Then go to Step 7.
Figure 8. Measuring Tank
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 9).
