Section 3. Controller Installation

3.1

Controller and Flow Cell Installation

The controller should be mounted on a wall or other
vertical surface within eight (8) feet (2.4 meters) of the
feeder, at least ten (10) feet (3 meters) away from the
edge of the water and within six (6) feet (1.8 meters)
of the GFCI power source. Use mounting screws or
anchors to mount the controller.

Flow Cell Assembly Installation

Mount the flow cell on a vertical surface within eight
feet (2.4 meters) of the controller.
Plumb it so the pressure difference between the inlet
(flow switch side) and the outlet is sufficient to ensure
flow through the flow cell. If the 3/8" tubing provided
is being used, a minimum pressure differential of 3 PSI
and 0.3 GPM is required to activate the flow switch.
It is also desirable to have filtered water pass over the
sensors to minimize cleaning.
There are two suggested plumbing installations for the
flow cell.

Plumb the inlet after the filter and the outlet after the
heater.

3.2.2 Pressure/Suction Method
Plumb the inlet after the filter and the outlet before the
pump. This ensures excellent flow but the flow must be
adjusted so the sensors are not subjected to a suction
environment. Open the sample port to verify that water
is flowing freely from it.

Water Supply Connections

The flow cell comes fully assembled, ready to install
with the 3/8" tubing provided. Other sized tubing or
1/2" hard plumbing can be used.
To use an alternative tubing, remove the 90 degree on/
off valves and plumb according to the application.
3.3.1 Saddle Clamp
1. If using a saddle clamp, drill a 7/16" hole in the
pipe. See Figure 7.
2. Insert the 1/8" compression fitting through the
clamp and place the nylon jam nut onto the
compression fitting.
