Rotor assembly
1. Remove the drain hose from the drain elbow.

3. Lift the valve cover away from the valve body.
4. Remove the rotor assembly from the valve cover; the white Teflon O-ring will remain in the valve cover.
5. Inspect the rotor plate’s surface; it should be smooth and free of any circular grooves or scratches; replace if
necessary.
6. Install the rotor assembly into the valve body ensuring that the
arrow on the worm gear is pointing directly towards the second
tooth on the worm drive shaft (facing the front of the control valve);
the 2 holes in the rotor assembly should now be exactly aligned with
the corresponding holes in the seal disk.

around the raised rib on the valve cover.

Seal disk
1. Remove the rotor assembly; refer to Parts Replacement “Rotor assembly”.

3. Inspect the seal disk; make sure the raised ribs are intact; the green Teflon coating may be worn off of the ribs,
but this won’t affect the sealing performance of the seal disk; replace if necessary.
4. Use silicone base lubricant to lubricate the green side of the seal disk.
5. Install the seal disk in the valve body, with the green side facing up.
6. Reverse the procedure for reassembly; refer to Parts Replacement “Rotor Assembly”.
