Pressure Chamber Housing Gasket and Felt Washer
Slide both the gasket and felt washer off the pressure chamber body (Figure 6).
Replace felt washer first taking care not to fold over washer as it is worked up
the pump chamber and into the pump locking ring (figure 7). The felt washer is
pre-lubricated to provide lubrication between the pressure chamber housing and
pressure chamber housing gasket. Ensure the felt washer is free of contamination
before installing. Replace gasket into the pump opening in the tank ensuring the
flanged end is up (if this is assembled backwards leakage will occur) (Figure 8).
Ensure that the sides of the gasket are inside the tank pump opening and the flange
is sitting level on the tank pump opening seal surface area.
5) Replace pump assembly into tank and into the piston cylinder which is mounted
on the bottom of the tank. Be careful not to damage the plunger seal as it seats into
the piston cylinder. It is recommended that you view through the tank fill opening
while performing this to achieve better alignment. If necessary you can also reach
in and use your hand to guide the plunger seal into the piston cylinder.
6) Position the pump outlet (hose connection) in the desired position. Tighten
the pump retaining ring onto the tank.
7) Reach into tank fill opening and attach agitator to pressure chamber body.
8) Connect linkage arm to the top of the pump assembly (see section covering
Installing The Pump Handle).
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). (Figure2).
