How Your Chlorinator Works
See Fig 1. The well pump is controlled by the pressure switch. A dedicated outlet for the Precision‐24 Pump is installed
and wired so it is energized when the well pump is energized. When the water pressure in the pressure tank drops below
the cut‐in point on the pressure switch, the well pump and metering pump turn on. As water is pumped through the
system, a small amount of chlorine is pumped into the water by the chlorine metering pump.
Fig 1: Typical installation with contact tank and carbon backwash or iron filter. NOTE – Precision‐24 Pump must be wired
so it swithes on and off with well pump by wiring to same circuit as well pressure switch. Alternatively a Flow Switch can
be used (Option 2 on next page). The Precision‐24 Pump cannot just be plugged into a wall and left to run for 24 hours a
day.
