Replacing the motor of the automatic cleaner

Replace the drive motor of the automatic cleaner about once every 3 years.

Replacing procedure

Loosen the 4 screws, and remove the cleaner cover.

Check the O-ring for deterioration (elasticity and cracking).

Remove the connector of the wiring of the motor. Do not strain the connector.

Loosen the 4 screws securing the motor platform, and remove the motor assembly.

Take out the set of thrust bearings (retain it for reuse).

Attach a new motor assembly in the reverse order.

Attach the connector of the motor.

Perform a test operation of the automatic cleaner to check the movement (refer to “
Cleaning test motion screen ” (page 36)).

Check all the screws in each section for looseness.

10.

Wipe off any dirt on the O-ring, place the cover on the O-ring, then tighten the
screws.

Note

When screwing a stainless steel bolt into a resin female screw, turn the bolt with your fingers without
using a tool. Screwing in the bolt using excessive torque will damage the screw.

WARNING

Unexpected operation of the unit may result in damage to the unit or an injury. Be sure to turn OFF the
power when replacing any parts.
