Introduction - Polaris Watermatic C-660 User Manual

I. Introduction
For your protection, read all instructions carefully before
installing or operating this automatic controller.
The Polaris Watermatic C-660 ORP/pH Controller is designed to
automatically monitor and maintain both the sanitizer level and
the pH balance in swimming pools, spas, or any circulating water
system that requires management of its water chemistry. The
C-660 Controller is designed for easy installation and simple
operation. It may be used with liquid feed pumps, granular feed-
ers, tablet erosion feeders, and ozone generators. It is not war-
ranted or recommended for use with chlorine gas systems.
The C-660 has two standard power receptacles for the ORP and
pH outputs. During the filtration cycle of the pool or spa, the
sanitizer level and pH balance are displayed on the controller's
ORP and pH digital readouts (see drawing below) and main-
tained by a constant measurement of the ORP (Oxidation-
Reduction-Potential) and pH balance of the water. If the saniti-
zer level (ORP) falls below the desired set point for the sanitizer
level, the controller will activate the chemical feeder until the pre-
set point is reached. The pH of the pool or spa is maintained in
a similar manner.
Various safety features prevent the feeding systems from activat-
ing if the sanitizer or pH balance are outside of the controller's
range. Additional safety features and options are described in
further detail in the Pre-installation section of this manual.
The C-660W model is a version of the C-660 designed to be
used with the G-1000 or G-7500 feeder. The controller is
equipped with a circular connector on the ORP output and
includes a cord for connection between the controller and feeder.
