INSTALLATION INSTRUCTIONS
Replacement Motor / Metal Geared Cam Kit
for 3/4” Single Disc Valve
IMPORTANT: If the geared cam on your system’s valve is black plastic (not silver
colored metal), it is incompatible with the new motor contained in this kit. When
replacing an old motor and/or an old geared cam, you must replace both
with the
ones provided in this kit:
1. Push the system’s bypass valve into the bypass position.
2. Unplug the system’s power supply from electrical power.
3. Remove the top cover to get access to the valve.
4. Locate the cable (red and black wires) running from the motor
to the electronic control board and unplug the 2-pin connector.
5. Remove the motor’s mounting screws and lift the motor off the
mounting plate.
6. Remove the plate’s mounting screws and lift the plate off the
valve cover. Set these parts aside, as they will be reused.
7. Lift the plastic bushing off the old geared cam and set this
bushing aside to be reused.
8. Lift the old geared cam off the stem of the valve rotor.
9. Examine the hole in the center of the new geared cam and
see how it has two flat sides, one longer than the other. Place
it gently over the stem of the valve rotor, oriented the same
way. Do not press it down yet.
10. Locate the lever on the microswitch and push it in (toward the
switch body). Hold it in this position while gently lowering the
geared cam onto the stem.
11. Release the microswitch lever. It should be resting in an
indent on the side of the cam - not bent down underneath the
cam.
12. Place the plastic bushing over the center of the new geared
cam.
13. Reinstall the motor plate with its screws onto the valve cover.
14. Install the new motor (screws provided) onto the plate,
making sure that the motor stem’s teeth engage properly with
the new geared cam.
15. Plug the new motor’s cable (red and black wires) into the cor-
responding 2-pin connector from the electronic control board.
16. Put the top cover back on the system, plug the power supply
back into electrical power and place the bypass valve back
into service position.
17. Start a recharge to make sure the motor runs and is properly
engaged to the valve rotor. Advance the valve through all
positions until it reaches service again.
