Step 1 - Rough In Wiring

• Pull three conductor 18 AWG LVT cable, up to 500 feet (150 m) for the float-

ing action signal.

• Strip wire to 3/8" (10 mm) for all terminal connections.

Step 2 - Mounting

• Using a Phillips screwdriver, remove the two screws in the corners of the

actuator cover. Remove the cover.

• Thread the anti-rotation bolt into one of the threaded holes on the mixing

valve. Do not align the anti-rotation bolt with the actuator motor corner cavity.

on.
