Test Cooling Tower
Conductivity (umhos) 1987 1400 - 2200 pH 8.71 8 - 9
Polymer (FAU) 122 70 - 150
Free Chlorine, ppm 0.30
0.1 - 0.5
Opening Comment Pyxis free chlorine monitoring & control panel is now functional.
• Thank you Don for mounting and getting set up. I landed wiring today and the bleach pump is now being controlled via the new control unit.
• New sensor was calibrated to match my field free chlorine test (0.30 ppm).
• Current setpoints:
◦ Bleach pump ON = 0.19 ppm
◦ Bleach pump OFF = 0.20 ppm
• I have a very tight deadband set in an effort to maintain tight control and consistency. As ambient temperatures increase, we can start to slowly bump up the free chlorine target setpoint.
• As discussed with Don, the setpoint can be adjusted on the Prominent controller.
◦ From the ‘Home’ screen — Select ‘Menu”
◦ Select ‘Adjust Setpoints’
◦ Select ‘Biotrol 12.5’
◦ Adjust accordingly and exit to home screen
• Legionella Testing
◦ Great Legionella results on our last round of testing — Final report previously sent
◦ I will send an invite as a reminder for the beginning of June
Thank you guys and please don’t hesitate to contact me if you have any questions.
