4.7 Startup

Once the controller has been set up for your application, start up is a simple process. Check your

supply of chemicals, turn on the controller power, calibrate all sensors as necessary, supply the

sensors with a flow of sample water, and it will start controlling.

4.8 Shut Down

To shut down the controller, simply turn off the power. All set points will be retained in memory.

It is important that the optional pH and ORP electrodes remain wet. If it is possible for these

electrodes to dry out, remove them from the flow assembly and place them in a cup or back in

their original soaker bottles containing either pH 4 buffer solution or cooling tower water. Take

care to avoid freezing temperatures when storing the electrodes to avoid breakage of the glass.
