IMPORTANT SAFETY INSTRUCTIONS
When using this electrical equipment, basic safety precautions should always be followed, includ-
ing the following:
• READ AND FOLLOW ALL INSTRUCTIONS
• WARNING: Risk of Electric Shock. Connect controller only to a grounding type recep-
tacle protected by a ground-fault circuit interrupter (GFI). CAT Controllers recommends
installation to a dedicated GFI circuit breaker performed by a licensed electrician.
• WARNING: Disconnect power before servicing. Other than the fuses, there are no user
serviceable parts inside the controller.
• WARNING: All power cords should be inspected frequently. Any damaged power cords
must be replaced immediately to reduce the risk of electric shock. Never operate a
controller without functional flow protection.
• WARNING: Installation requires a properly located GFI protected receptacle. Never use
an extension cord for electrical connections to the controller.
• WARNING: Always mount controller in a safe area not subject to damage by moving
objects. Never bury controller power cords.
• WARNING: Any person using, adjusting, or monitoring the controller must be at least 18
years of age and be familiar with these instructions and the contents of this manual.
• WARNING: Always take and record manual water chemistry readings in conformance
with Health Department requirements. Although automated controllers are a great aid in
maintaining healthy water quality, controllers are not a substitute for manual water test-
ing with an accurate test kit.
• WARNING: Always read and become familiar with Material Safety Data Sheets (MSDS)
and safe handling instructions for all chemicals used with the controller.
• Caution: The automatic controller should not be installed where it is accessible to the
public.
• Overfeed Timers prevent potentially dangerous, unintentional dispensing of chemicals.
CAT Controllers recommends always having the “Overfeed Timeout” functions enabled as
a precautionary measure. By disabling the “Overfeed Timeout” the overfeeding of chemi-
cals could occur and create unsafe water chemistry conditions. Overfeeding chemicals is
dangerous and could potentially harm patrons.

Introduction
Description
The CAT 5000 revolutionizes the manner in which water quality can be monitored and maintained.
A pool operator typically checks, records and adjusts pool or spa water chemistry hourly at best.
The CAT 5000 continuously samples pH and sanitizer activity, adjusting the feeding of chemicals
on a basis proportional to the demand. Hourly water quality readings are sent along with any
alarms or service requests through a wireless network to the POOLCOMM web server for remote
monitoring and management through any internet connection. NOTE: The POOLCOMM website is
a subscription based service. Monthly charges apply.
From the website, the subscriber can monitor water quality, print charts, graphs and logs, change
controller settings, and designate contacts for outbound notification via email, cell phone or PDA.
Optional digital flow and level sensors are available to monitor flow rate, chemical storage tank
levels, and even automate water level control.
The results include elimination of “human error”, accurate and reliable maintenance of chemical
levels twenty-four hours a day, compliance with Health Department operating standards, reduced
burden on operating staff, and a reduction of chemical usage and costs. The CAT 5000 control-
ler and POOLCOMM water quality management website together provide unprecedented control,
access and documentation.

What’s Included:
Description
The following is a description of the components incorporated in a typical CAT 5000 wireless water
quality control system:
The Professional-Series pH Sensor samples water from the filtration system and sends signals to
the controller indicating the acidity of the water. The ideal pH range for pools and spas is 7.4 - 7.6.
The CAT 5000 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.
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 5000 controller is preset from the factory
to maintain ORP at 650 millivolts.
The Flow Sensor monitors the rate of flow across the pH and ORP sensors and signals the control-
ler 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 pH, ORP and Flow sensors while
ensuring ideal hydraulic conditions to maximize sensor performance and life.
The CAT 5000 Controller scans and interprets the signals from the pH, ORP, flow, and optional
digital flow-rate and level sensors, displays water quality readings and alarms in alphanumeric
format, and activates chemical feeders in proportion to demand to maintain pH and ORP setpoint
levels.
The controller incorporates audible and visual safeguard alarms for out of range conditions and
menu-driven control of setpoints, alarms, and a host of advanced features. The CAT 5000 control-
ler also features an internal transceiver for wireless transmission of data between the controller
and POOLCOMM website.
The Level Sensors (optional) provide signals to the controller indicating low pH chemical tank level,
low ORP tank level, and low water level.
The Digital Flow Sensor (optional) provides a flow rate to be displayed by the controller and an
alarm indication when filter maintenance is required.

Installation
Installation Procedure:
The key to a successful flow cell installation is in the plumbing. A pressure differential is required to
allow clean, untreated water to pass through the cell and across the sensors. We recommend using
the enclosed tubing and fittings to create a pressure-suction “loop” line.
Follow the directions below for installation and refer to the Installation Diagram on page 6.
1. Turn off heater, chemical feeders, pump, and any other related equipment. Relieve pressure
from filtration system.
2. Select a convenient mounting location for the controller unit which will meet the following
criteria:
a. Facilitates a combined (influent and effluent) maximum tubing run of 30’.
b. Located a minimum of ten feet from pool or spa.
c. GFI protected power source available.
d. Easily accessible to pool or spa operator.
e. Away from corrosive materials and physical hazards.
3. Securely mount PVC Backboard on vertical wall.
4. Drill and tap a 1/4” NPT port at a location just downstream of the filter, but upstream from
any chemical injection point. Install a tubing connector, and run flex tubing to the influent
flow cell port.
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. Cut a 3” length of flex tubing and insert into the sample stream port.
7. Remove pH and ORP sensors from the plastic storage bottles and save bottles and storage
fluid for future use. Thread sensors into flow cell.
8. Remove BNC protective covers from left side of controller unit and store for future use.
These covers protect the controller unit from electrostatic discharge (ESD) and should be
used whenever handling or transporting the controller unit.
9. Connect the pH, ORP and Flow sensor cables to the controller unit as labeled. Sensor cables
are constructed from a specialized material - never cut or splice.
10. Mount satellite antenna outdoors, as high as possible, with a clear view of the sky. Carefully
route antenna cable and connect to controller.
11. Drill and tap a 1/4” NPT port at the location from which temperature measurement is
desired (upstream from heater). Insert temperature sensor and connect to controller.
12. If new or additional chemical feeders are to be used with the controller, install according to
manufacturer’s instructions at this time.
13. Connect chemical feeders to the controller as labeled (See diagram below).
14. Check all electrical and mechanical connections. Resume filtration system operation and
check for any leaks.

Pool 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 5000.
The table below indicates generally accepted guidelines. Always maintain water chemistry accord-
ing to standards set by your local or State Health Department.
Test Minimum Ideal Maximum
pH 7.2 7.5 7.8
Free Chlorine (PPM) 1 2 3
Bromine (PPM) 2 3 4
Cyanuric Acid (PPM) 0 - 100
ORP (mV) 650 - -
Total Alkalinity 80 - 120
Calcium Hardness 200 - 400
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 Controllers, 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. The ORP setpoint will need to be changed periodically as described later in this section if the
goal is to provide consistent sanitizer residual levels rather than consistent control of ORP.
Configuration
Overview
The CAT 5000 features a bright, menu-driven vacuum-fluorescent display which makes setup and
programming simple in any lighting conditions. The menu structure is divided into two sections; the
Operating Menu is intended for the end user to manage settings which are accessed on a frequent
basis, while the Configuration Menu is used to set up advanced features which truly customize the
controller to meet the individual requirements of the application.
The keypad provides intuitive access to the controller functionality as described on the following
