1) Insure the tank and pressure chamber contents are emptied and pressure
has been released in the pressure chamber. To release pressure in the
pressure chamber activate shut-off valve and release all pressure.
2) Reach into tank fill opening and remove agitator bar from pressure
chamber body (Figure 1).
3) Disconnect linkage arm from the top of the pump assembly (see section
covering Installing The Pump Handle). (Figure 2).
4) Loosen pump locking ring and remove entire pump assembly from tank
(Figure 3).
Check Valve
Remove check valve cartridge assembly from bottom of pressure chamber
utilizing pump handle clip (clip has flat blade incorporated into end). Place
flat blade into slot in bottom of cartridge and unscrew. Once cartridge has
been removed it can either be replaced as an assembly or rebuilt. To rebuild
disassemble two halves of cartridge and replace seal and/or ball (Figure 4 and
5). The seal mounts inside the larger of the two halves of the cartridge. The
seal counterbore side mounts into the grooves in the cartridge halve. Pump
performance my be affected if this is not assembled correctly.
Plunger Cup
Once the check valve has been removed the plunger cup can be replaced as the
check valve housing holds the plunger cup in place to the bottom of the pressure
chamber body. The bottom of the pressure chamber body has a groove in it to
accept the raised ring on the plunger cup. It is important to insure that these
two surfaces are aligned and mated before tightening the check valve. Pump
performance may be affected if this is not assembled correctly.
