Hayward Sense and Dispense Model: AQL-CHEM - Page 3

Compatibility The AQL-CHEM is compatible with all Hayward Aqua Rite Pro and Pro Logic pool controls. An AQL-CL chemistry kit must be used with the Pro Logic if automatic chlorine generation is desired. The AQL-CHEM is not compatible with Aqua Rite or Aqua Logic controls. Installation Overview Installing the AQL-CHEM requires the following steps: • Mounting the Probe Cell • Plumbing the Probe Cell • Installing ORP and pH probes • Wiring probes to Probe Cell communication box • Wiring the Probe Cell to the Aqua Rite Pro or Pro Logic • Wiring the pH Dispense Pigtail to the Aqua Rite Pro or Pro Logic • Configuring the Aqua Rite Pro or Pro Logic • Validating Operation • Establishing Maintenance Schedule Materials Needed for Installation • 7/16" drill bit • ¼" NPT tap • Two small adjustable wrenches if side mounting to Aqua Rite Pro or Pro Logic • 3/16" drill bit if side mounting to Aqua Rite Pro or Pro Logic • Deburring tool or file if side mounting • Tape and scissors if side mounting to Pro Logic (for drill template) • Mounting hardware if surface mounting (not side mounting) • Flex tubing cutter • Water-tight strain relief for dispense pigtail • Flathead screwdriver and mallet to remove knock-out and install strain relief • 120VAC Ground Fault Circuit Breaker (GFCB) for powering 120VAC dispense pigtail or 240VAC (GFCB) for powering 240VAC dispense pigtail • Extra wire, wire strippers, and wire nuts could be helpful in some installations • Any items that would be required for wiring and installation per local code Before carrying out any part of the installation, be sure to shut off input power to the Aqua Rite Pro or Pro Logic. Turn off the pool filter pump, water features and any other related equipment. Relieve pressure from the pool filtration system. Mounting the Probe Cell The Probe Cell can be mounted directly on the side of the Aqua Rite Pro/Pro Logic or mounted up to 15' away (limited by length of Probe Cell cable). The key to successful Probe Cell installation is in the plumbing. A pressure differential is required to allow clean, untreated water to pass through the cell and across the probes. Consider this when looking for an ideal mounting location. 2
