Risk of Chemical Exposure Do not shut down circulation and control system immediately after using pool, spa or hot tub. Systems must operate until water chemistry is stable. Systems must be restarted before water chemistry is out of NSPI recommended ranges or water chemistry must be manually corrected.

The internal step-down transformer has a class-two energy limiting rating to provide for electrical safety. When automating any body of water, it is desired levels in a relatively short period of time. Generally, automating an existing body accordingly. If feeder is unable to keep up with demand in a short period of time, automation becomes ineffective.

Never mount a controller above or near an acid tank. Never mount a controller in a location accessible to the public. Install the controller in an area protected from natural elements (sun, rain, freezing, etc.). See appendix for typical feed system schematics. Once the site is selected, obtain screws or anchors to securely mount the controller on the wall or a panel. Screw slots are provided in the controller enclosure. Access to flow switch wires, acid/base changes and terminals is located on the back ofh the back of the enclosure.from wall/panel, remove four screws holding enclosure panel to enclosure body.
