4.0 Installation
4.1 Locating the controller
Install the chemical pump and erosion feed systems as shown in manuals included with the
feeders. The controller may need to be set for the particular feeder system used. Before
installing the controller, it is important to do a site assessment to consider where and how you
will mount the unit. The controller should be mounted on a wall or other surface within eight
feet of the feeder, at least ten feet away from the edge of the water, and within six feet of the
GFCI power
source. Never mount a controller above or near an acid tank. Never mount a
controller in a location accessible to the public. See appendix for typical feed system
schematics.
4.2 Mechanical Installation
Once the site is selected, obtain screws or anchors (mounting screws are not provided with
controller) to securely mount the controller on the wall or a panel. Install a screw in the
wall/panel where the top center of the controller is to be located. Leave ¼ inch of the screw
out of the wall to hang the controller from the keyhole located on controller’s back. Remove
the power panel access cover and install screws through the two holes located at the bottom
left and right corners of the controller. Leave the power access panel cover off.
