FLOW SWITCH CLEANING
Frequency
The flow switch should be checked periodically. This to make sure it is free and the chamber is free from any
debris that would prevent its proper operation.
The frequency required will vary by installation.
Check the conductivity monthly with a handheld device and compare with the value indicated on the controller.
After cleaning, if the value deviates from the reading on the handheld device, see calibration procedure below.
CALIBRATE THE SENSOR
To calibrate the sensor, from the home page return to the list of inputs:
-
Highlight Conductivity sensor (S1)
-
Press the Enter key
-
Press the Calibrate key
-
Select one of the calibration routines
