Battery

To remove the electrical wiring base, turn it round and extract it from its housing.

–

ATTENTION: If the battery is not activated the battery alarm will be displayed.

CAUTION!

The controller is congured to automatically execute a daily rotation cycle to ensure ef-

cient ball operation and cleaning. This occurs directly after the disinfection program, if

active, or after 24 hours have elapsed if disinfection is not active. Deactive this function

through the ANTI-CLOG setting by entering the release code 5566 and conrming with ON-

OFF. Eliminating this function increases the risk of deposits forming on moving parts of

valve. If it is necessary to eliminate the disinfection function as well, proceed as follows:

1. disable the ANTI-CLOG function; 2. eliminate the disinfection function.
