Foreword
Congratulations on your wise investment. The product you have selected from the CAT 2000 line
of automated controllers should provide you with substantially reduced chemical maintenance, im-
proved compliance with Health Department operating standards, chemical cost savings, and many
years of reliable operation. All CAT controllers incorporate state of the art microprocessor-based
design technology to provide sophisticated control functions at an affordable price.
Although CAT controllers are relatively simple to install, please take the time to read this entire
manual, compare package contents with the parts list, and gather all tools required before begin-
ning installation. Improper installation may void the warranty and create unnecessary hazards.
Properly preparing for installation will also reduce facility down time.
For the purposes of this manual, it is presupposed that the installer is familiar with the physical
characteristics of the pool or spa to be automated. As is the case when installing any filtration
system component, all recirculating pumps, heaters, etc. need to be turned off prior to installation
of the controller. If the filtration system is located below water level, additionally adjust all valves
required to eliminate pressure from the system.
Physically, installation of a CAT controller is no more challenging than installation of a chemi-
cal feeder. Any swimming pool contractor or maintenance engineer should have the tools and
knowledge to perform the installation. Our technical support line can also be used to answer any
questions pertaining to controller installation.
Remember that your new CAT controller is not a substitute for performing and recording manual
water testing in conformance with your state or local health department regulations. Never operate
a water chemistry controller without a flow sensor, power interlock, or other means of ensuring that
chemicals will not be fed without proper filtration system recirculation.
