the motor to the cover of the unit. Place the new drive
adapter on the motor and tighten the screws to secure
the motor to the cover. To replace the pump, take the
cover off the pump to expose the secure screw. Take

If converting from a detergent pump to a detergent valve, the

will fit where the valve bracket cover on the unit was placed.
To replace the detergent valve, disconnect all power to the unit.
Remove the old valve from the unit by disconnecting the wires
and removing the screws from the bottom of the unit. It may be
necessary to remove the valve cover on the inside of the unit to
remove the wires. Place the new wire assembly on the new valve.
Replace the old valve with the new valve. Secure the valve with
the screws provided. Replace the valve cover with the screws to
secure it to the enclosure. Plug the wires into the proper place on
the control board. If converting from a pump to a valve, place the
pump blank cover on the front of the unit and secure with a screw.

control 3 products. The picture on the next page shows a 3 product control board with the sanitizer spades and
potentiometer. These are necessary to power the sanitizer pump and control the amount of sanitizer dispensed.
