Keep sufficient chemical supplies on hand to replenish as necessary.

If one or more chemicals are not going to be used, the system can be set so that the related sensor is disabled. To disable the sensor, press the appropriate button until the light goes off. To reactivate a disabled sensor, make sure liquid chemical is present in the tubing and press the appropriate button again until the light turns on.

To Recalibrate Sensors

If the Chemical Sensing Device does not indicate the presence or absence of liquid chemical properly, it may be necessary to recalibrate the sensor by disabling and then reactivating the sensor. To disable the sensor, press the appropriate button until the light goes off. To reactivate a disabled sensor, make sure liquid chemical is present in the tubing and press the appropriate button again until the light turns on. If sensor is enabled while tube is empty, device may not operate properly. If the Chemical Sensing Device does not indicate the presence or absence of liquid chemical properly, contact your local Hobart Service office.
