MAINTENANCE
The only recommended maintenance required on your controller is periodic inspection of the
conductivity sensor. Clean the probe using a mild cleaning agent such as detergents or 5% HCl
(removes scaling deposits). It is recommended that you establish a regular maintenance schedule
designed to meet the needs of your particular application. All other service should be performed
by factory authorized personnel only. Modifications to or tampering with the circuit level
components makes all warranties, written or implied, and/or manufacturer’s responsibility for this
controller null and void.
