Introduction
Congratulations on your wise Investment and welcome the world of chemical automation. The product you have selected from the CAT 1000®line of auto-
mated controllers should provide you with substantially reduced chemical maintenance, improved compliance with safer water quality 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 beginning 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 recirculation pumps, heaters, etc. needs to be turned off prior to the 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 chemical feeder. Any Swimming pool contractor or maintenance
engineer should have the tools and knowledge to perform the installation. Out technical support line can also be used to answer any question pertaining to
the controller installation.
Remember that your new CAT controller is not a substitute for performing regular manual water testing. 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.
Congratulations on your purchase and welcome to the world of chemical automation. Please complete and return your warranty registration today.
Important Information
Chemical Automation with the CAT-1000-ORP
A pool operator typically checks and adjusts pool and spa water chemistry hourly at best. The CAT 1000 continuously monitors the ORP/sanitizer activity and
is constantly adjusting the feeding of the sanitizer on a basis proportional to the demand. The result includes the elimination of “human error”, inaccuracies
and provides reliable maintenance of chemical levels twenty-four hours a day. The controller also provides compliance with safer water chemistry standards,
reduced burden on operating staff, and a reduction of chemical usage and costs.
The following graph compares typical ORP levels when chemistry is adjusted manually versus automatically with the CAT-1000-ORP controller.

What is ORP?
When we are measuring ORP we are measuring the quality and the capability of the oxidizing component in the water. The oxidizing component can come
from chlorine, bromine, Ozone, non-chlorine shocks, hydrogen peroxide, etc. As we all know sanitizers will only work upon the result of a properly balanced
body of water. This is where ORP comes into play. ORP only measures specifically the ability and/or quality of the oxidizer present in the water. Its ability/
quality are reduced or increased in relation to the other water chemistry variables, pH, total alkalinity, total dissolved solids, temperature, the presence
cyanuric acid, the presence of chlorine neutralizers, etc. Simply put, it does not matter how much sanitizer is in your body of water, if the other chemistry
variables are not balanced the sanitizer WILL NOT WORK to its full “potential”.
Oxidation, in the past, was merely defined as the interaction between oxygen molecules and all dissimilar matter that they may come in contact with. Upon
the discovery of electrons, oxidation came to be more accurately defined as the loss of an electron when two or more matters interact. When a sanitizer
interacts with unwanted substances, it steals an electron from the substance changing its chemical make up in turn helping to burn the substance up.
However, now that the sanitizer has gained an electron it has “reduced” the sanitizer’s electrical energy making the sanitizer less effective.
Reduction occurs when a substance gains an electron after the oxidation process has occurred. The atom or oxidizer that gains the electron may lose their
ability to further oxidize substances or they will combine with other substances in the water resulting in by-products and/or combined chlorine.
Potential is the concept of stored energy within. The potential as it relates to ORP, relates to the potential of the sanitizer present in the water to oxidize
contaminants. The potential is measured in millivolts, a very small electrical reading. When an oxidizer is present in water it is attempting to steal negatively
charged electrons from any substance. If the substance is a platinum or gold electrode (ORP Sensor), once the oxidizer steals the negatively charged elec-
tron from the electrode the electrode will then generate more positively charged energy, therefore increasing ORP. The more oxidizer present in the water
the more positively charged the electrode becomes.
When discussing ORP, often times people like to leave out the reduction part of it. Why? Because we are measuring the potential of the oxidizer to steal
electrons, not the potential of substance being reduced or gaining electrons. However, if there are exactly the same amount of reducers, oxidizer atoms that
have gained electrons and oxidizer atoms that have not yet gained electrons, there will be no “Potential” for future oxidation. That is why we must continually
sanitize water or eventually it will result in the sanitizer being used up.
pH is the most important factor in keeping the strength of your sanitizer. The Potential of Hydrogen or Power of Hydrogen relates to HOCL and OCL. If you
have a lower pH, the HOCL (the stronger chlorine), will be more active and the sanitizer will be more effective. If the stronger part of your chlorine is working
harder and is more active, the more oxidizing potential it will have. Lower pH means more available H+ in the water, which means that the water will not
take the H+ as frequently from the HOCL, resulting in more HOCL and less OCL (your weaker free chlorine).
In conclusion, ORP (Oxidation Reduction Potential) is the measurement of the potential of the oxidizer present in the water to remove electrons from
unwanted substances. Once the unwanted substance loses its electron its chemical structure is changed and it is “burned up”. ORP is not tricked by the
effects of other variables present in the water. ORP tells you the true effectiveness of your sanitizer based solely on its ability to oxidize in that specific body
of water. The millivolt reading of 650mV has been designated as the potential needed for safe drinking water. The relationship of pH, FAC, and ORP are very
important. We must keep a more acidic (7.5 or lower) pH in our water to make sure our HOCL is more active which gives it more oxidizing ability, in turn
raising our ORP reading. Automated pH and ORP controllers constantly monitor both the pH and ORP in the water and make the necessary adjustments to
keep a proper pH and a proper amount of oxidizer present in the water to keep your water safe 24/7.
Components of the CAT-1000-ORP System
The following is a description of the components incorporated in a typical CAT 1000 controller system:
The Professional-Series ORP Sensor samples water from the filtration system and sends signals to the controller indicating the Oxidation Reduction
Potential (redox) of the water. ORP is an actual measure of sanitizer activity (chlorine, bromine, ozone etc.) and bacteriological water quality rather than an
expression of chemical residual levels. The CAT 1000 controller is preset from the factory to maintain ORP at 650 millivolts.
The Flow Sensor (required) monitors the flow across the ORP sensor and signals the controller to disable automated chemical feeding during periods
when the filtration system is off or low recirculation flow is detected.
The Flow Cell provides a convenient location for mounting the ORP sensor while ensuring ideal hydraulic conditions to maximize the sensor’s performance
and life.
The CAT 1000 Controller unit scans and interprets the signals from the ORP sensor, display water quality readings in digital format and activates the
chemical feeder in proportion to the demand required to maintain the ORP setpoint level. The unit incorporates audible and visual safeguard alarms for the
out of range conditions and mode selections to manually feed or disable feeding. The CAT 1000 controller unit also features an internal micro-computer for
unsurpassed accuracy, adaptability and ease of use. All user-entries and adjustments are made through the touch-screen interface front panel.

5. Drill and tap a 1/4” NPT port at a location subject to vacuum or reduced pressure. Install the remaining tubing connector and run flex tubing to the effluent
flow cell port.
6. Remove ORP sensor from the plastic storage bottle and save bottle and storage fluid for future use. Apply Teflon tape and thread sensor into flow cell.
7. Remove BNC protective cover from the left side of controller unit and store for future use. This cover protects the controller unit from electro-static dis-
charge (ESD) and should be used whenever handling or transporting the controller unit.
8. Connect the ORP and Flow sensor cables to the controller unit as labeled. Sensor cables are constructed from a specialized material – never cut or splice.
9. If new or additional chemical feeders are to be used with the controller, install according to the manufacturer’s instructions at this time.
10. Connect chemical feeder to the controller as labeled.
11. Check all electrical and mechanical connections. Resume filtration system operation and check for any leaks.
Preparing Water Chemistry
Now that your new controller has been physically installed, water chemistry should be tested and adjusted prior to initiating automated control of the pool or
spa. Confirm that your pool or spa water conforms to the following ranges before powering on and setting up the CAT 1000.
All CAT water quality controllers maintain sanitizer levels (chlorine, bromine, ozone, etc.) based on ORP. Although ORP is a superior index of water quality
compared to part per million sanitizer residual levels, factors such as pH, cyanuric acid concentration and total dissolved solids can affect sanitizer residual
readings relative to ORP.
CAT strongly recommends establishing desired pH, sanitizer residual, calcium hardness, total alkalinity, temperature and cyanuric acid levels prior to initiating
automated control of the pool or spa to facilitate securing to the rebar. Once the niche is tied in place, confirm that it is still plumb and that the distance from
the outer wall to the niche flange is the correct beam dimension.

Operation
Once the desired start up chemistry parameters have been established, you are ready to set the CAT 1000 to automatically maintain ORP. Please
refer to illustration 3 for controller unit button designations. Button designations appear in bold type.
Changing the ORP Setpoint
The CAT 1000 is preset from the factory to maintain an ORP of 650 mV. This is the generally accepted world standard for safe drinking water. In
order to meet Health Department standards for a particular pool or spa, the ORP setpoint may be changed to maintain a desired sanitizer level
by performing the following:
1. Manually test pool or spa to confirm that the current sanitizer reading (chlorine, bromine, etc.) is the level you wish to maintain.
2. Note the ORP reading displayed by the controller.
3. Press the ORP Setpoint Adjustment Button (#4) until the green “SET” LED is illuminated.
4. Press the arrow-shaped ORP Channel Increase Button (#2) or ORP Channel Decrease Button (#3) until the digital display matches the
ORP reading previously noted.
5. The controller will automatically return to the normal operating mode after twenty seconds, storing any changes.
The ORP setpoint should be changed as needed to maintain sanitizer residuals in conformance with Health Department standards.
Manually Activating ORP Feed
To manually enable the ORP chemical feeder press the ORP Channel Mode Selection Button (#5) until the green “MANUAL” LED is illuminated.
The chemical feeder will operate continuously for 30 minutes, and then automatically revert to “Auto” to prevent accidental over-feeding.
Manually Disabling ORP Feed
To manually prevent operation of the ORP chemical feeder press the ORP Channel Mode Selection Button (#5) until the red “OFF” LED is
illuminated. Automatic ORP feeding will be disabled. So that the user may have time to enter selections, the chemical feeding cycle will not be
interrupted for approximately ten seconds.
Automatically Controlling ORP Feed
For automated control of the ORP chemical feeder press the ORP Channel Mode Selection Button (#5) until the green “AUTO” LED is illumi-
nated. The chemical feeder will operate automatically in proportion to the chemical demand. So that the user may have time to enter selections,
the chemical feeding cycle will not be interrupted for approximately ten seconds.
About Proportional Feed
The CAT 1000 features an advanced proportional feed algorithm which constantly analyzes demand for chemicals and initiates feeding in inter-
vals based on the relationship between setpoint and actual water sample values. This feature is highly valuable in maintaining precise control of
water chemistry in most applications.

Maintenance
CAT 1000 Controller
The CAT 1000 controller unit is virtually maintenance free. Cleaning of the enclosure, front panel and flow cell can be performed using a clean, soft
cloth moistened with mild soap and water solution or glass cleaner. Use of abrasives or harsh chemicals may damage the enclosure and membrane
switch panel.
Water Maintenance
Always test and record water chemistry readings in compliance with the Health Department requirements using a quality manual test kit.
Sensor Maintenance
The sensor must be clean and free from oil, chemical deposits and contamination to function properly. After saturation in pool or spa water, the sen-
sor may need to be cleaned on a weekly or monthly basis depending on bather load and other facility-specific characteristics. Slow response and
inconsistent readings are indications that the sensor is in need of cleaning.
To clean the sensor, disconnect from the controller and carefully remove the sensor from the flow cell. Clean the reference junction (the white Teflon
ring at the bottom of sensor body) with a soft toothbrush and regular toothpaste. A household liquid dishwashing detergent may also be used to
remove any oil. Rinse with fresh water, replace Teflon thread-seal tape and reinstall the sensor. Hand tighten only.
Never allow the ORP sensor to dry completely. Drying will damage the reference junction and void the sensor warranty.
Sensor Replacement
CAT Professional Series ORP sensors are engineered to provide the highest performance and longest possible functional service life. If a properly
cleaned sensor provides unstable readings, the sensor should be replaced. For optimum controller performance, always use genuine CAT Professional
Series sensors.
Sensor Storage
Exposure to atmospheric conditions will cause the sensors to dry out. Always remove and properly store the ORP sensor in the soaking cap provided
whenever the sensor is to be removed or stored for one hour or longer. Although CAT Professional Series sensors are freeze-resistant, they must be
protected from freezing temperatures when not in use.
Store the sensor in the soaking cap provided, making sure that the container is filled with the original storage solution or clean water. If the storage
container has been misplaced, store the sensor in a small glass or plastic container with clean water covering sensor tips.
Controller Storage
The controller unit is subject to damage by electro-static discharge (ESD) when the sensor cables are disconnected. Always reinstall the BNC protec-
tive covers prior to storing or transporting the CAT 1000 controller unit.
Winterization
The ORP sensor should be prepared for storage as outlined above and protected from freezing temperatures. Although the CAT 1000 is designed to
withstand a broad temperature range, winter storage in a secure location is desirable.
The flow cell and poly tubing must be drained prior to exposure to freezing temperatures. Either purge all water using compressed air or thoroughly
drain through the valve ports and tubing connections.
