1. If trouble shoo�ng guide suggests replacing the control box follow the direc�ons
below.
2. Remove 6 screws #1 and remove cover plate #2, Diagram C.
3. Unthread transducer #19, Diagram C, from pump housing #9, Diagram A.
4. Disconnect motor leads from circuit board. See Diagram "D/E"
5. Remove 3 mounting screws #17 Diagram C. Unthread the filter housing for easier access.
6. Remove control box containing circuit board, On/Off switch and poten�ometer.
7. Replace in reverse order. Note: Removing motor housing will make it easier to

If trouble shoo�ng guide suggests replacing the poten�ometer follow the direc�ons below.
1. Remove 6 screws #1 and remove the control box cover #2 Diagram C.
2. Disconnect the leads from poten�ometer #11 to circuit board and remove knob #15 on Diagram C.
3. Replace in reverse order.
REPLACE TRANSDUCER
Follow pressure relief procedure before attempting to serviceor repair unit.
If trouble shoo�ng guide suggests replacing the transducer follow the direc�ons
below.
