IntelliChlor Installation and User’s Guide
Loop Plumbing Diagram
The IntelliChlor will operate in water flow rates from 15 gallons per minute up to 110 gallons per minute (the
limit of 2” plumbing). For flow rates over 80 gallons per minute, it is recommend that you use a bypass loop
(shown below) for best chlorine production. Installations with flow rates over 80 gallons per minute are those
that have in-floor cleaning systems or boost pumps. These systems should use a bypass loop with the
IntelliChlor.
