Panel mount hardware should support 25lbs. For hole locations, see the mounting hole

3.4 Sensor Installation
The controller is supplied with a temperature compensated toroidal conductivity sensor
(probe). Install the sensor at some point in your process where chemical and water are
thoroughly mixed. The probe should also be located in a position where adequate flow is
going around and through the probe
(Fig. 4)
so that the controller will be able to display
a good measurement.

3.5 Flow Sensor Switch
If your controller is provided with a flow switch, install the flow switch so that flow
enters into the bottom of the flow switch tee, and out of the side of the tee. The flow
switch must always be installed in a vertical position so that the sensor wire is coming
out of the top, and the internal (red) flow shuttle is able to rise when there is flow and
drop when there is no flow. The flow switch is activated when 1 GPM (3,8 LPM) is
going through it, and is deactivated when the flow drops below 1 GPM (3,8 LPM).
