If a ball valve is installed down line from the pump, close it.
2.
Remove and save the protective plug over the service screw and turn the screw clockwise (see Figure 26). As
the screw approaches its bottom position, you will hear the system depressurizing. Continue turning the screw
until it can go no further. When the screw is all the way down, back off the screw 4 turns to lift the check valve

Get the siphon cartridge from the kit and apply a coating of petroleum jelly onto the three o-rings on the
outside of the siphon cartridge.
5.
Insert the siphon cartridge into the siphon port (see Figure 27). Swivel the outlet port of the siphon in the
desired direction, and then hand tighten the siphon’s retaining hex body. Torque the body to 25 - 30 ft-lbs (34

6.
Remove the 1/4’’ NPT plug from the siphon outlet port and attach siphon system tubing.
Before installing pipe threads, apply an adequate amount of fresh, UL classified for
petroleum, non-setting thread sealant. For AG applications, Loctite 564 is
recommended for all field serviceable pipe threads. Apply sealant in a manner that
prevents it from entering and contaminating hydraulic cavities.
7.
Turn the service screw counterclockwise all the way up. As the screw approaches its top position, the check
valve will drop into position.
