Introduction
Description
A pool operator typically checks and adjusts pool or spa water chemistry hourly at best. The HCC
2000 continuously monitors pH and sanitizer activity, constantly adjusting the feeding of chemicals
on a basis proportional to the demand. The results include elimination of “human error”, accurate
and reliable maintenance of chemical levels twenty-four hours a day, compliance with Health
Department chemistry standards, reduced burden on operating staff, and a reduction of chemical
usage and costs.

automatically with the HCC 2000 controller:

Description
The following is a description of the components incorporated in a typical HCC 2000 controller
system:
The pH Sensor samples water from the filtration system and sends signals to the controller indi-
cating the acidity of the water. The ideal pH range for pools and spas is 7.4 - 7.6. The HCC 2000
controller is preset from the factory to maintain pH 7.5. If pH is maintained below 7.4 (too acidic),
eye irritation, corrosion of equipment, and damage to the pool or spa surface can occur. If pH is
maintained above 7.6 (too alkaline), sanitizer activity is reduced, water may become cloudy, and
eye irritation may result.
