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 6000. The table on the following page indicates generally accepted guidelines. Always maintain water chemistry according to standards set by your local or State Health Department. Test Minimum pH 7.2 Free Chlorine (PPM) 1 Bromine (PPM) 2 Cyanuric Acid (PPM) 0 ORP (mV) 650 Total Alkalinity 80 Calcium Hardness 200 NaCl/Salt (PPM) 2500 **Refer to manufacturer's recommendations. Ideal 7.5 2 3 4000** Maximum 7.8 3 4 100 120 400 5000 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. System Operation Overview The CAT 6000 utilizes a bright, LCD interface and five touch-sensitive buttons to display an array of water chemistry characteristics as well as water quality control information and alarms. Status information can be seen in the status icon bar at the top of the screen. This bar indicates any present alarms, active feeds, the flow status, and the network connectivity status of the unit. 15 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
