Description

The AQL-CHEM is an ORP and pH sensing kit that is offered as an accessory for all
Hayward Aqua Rite Pro chlorine generators and Pro Logic pool controls. With the
AQL-CHEM, the Aqua Rite Pro or Pro Logic can provide a fully integrated chemistry
solution for your pool. The AQL-CHEM continuously tests the pool's sanitation and
pH levels allowing the Aqua Rite Pro or Pro Logic to automatically generate the
correct amount of chlorine and dispense the proper amount of pH reducer. Together,
they provide an automated system controlling both sanitization and pH balance.

The AQL-CHEM comes with two pigtails (120VAC and 240VAC) for connection to a
pH reducing device like a peristaltic pump or solenoid valve (not included) that re­quires a line cord receptacle. For easy integration, Hayward offers the AQL-CHEM2
(120VAC) and AQL-CHEM2-240 (240VAC) CO2 dispense kit that plugs into the pigtail
and will reduce the pool's pH level by injecting CO2 into the pool water.

What's Included

The AQL-CHEM comes with everything needed to allow the Aqua Rite Pro or Pro
Logic to sense ORP and pH levels. The following is a description of the included
components:

Professional Grade ORP probe- Samples water from the pool filtration system and
sends signals to the Aqua Rite Pro or Pro Logic indicating the oxidation-reduction
potential (redox) of the pool water. ORP is an actual measurement of sanitizer activity
and bacteriological water quality rather than an expression of chemical residual levels.
ORP is not fooled by the effects of pH, TDS (total dissolved solids) and other factors
giving a more accurate measurement of the effectiveness of chlorine and water qual­ity.

Professional Grade pH probe- Samples water from the pool filtration system and
sends signals to the Aqua Rite Pro or Pro Logic indicating the acidity of the water.
When used with a Hayward AQL-CHEM2 or other pH dispensing device, the Aqua
Rite Pro or Pro Logic can keep the pool water's pH level balanced.

Probe Cell: The Probe Cell is used to house the probes and provide a location for
water collection and testing. Two hoses are provided to connect the Probe Cell to the
supply and return sides of the pool filtration system. The Probe Cell can be mounted
directly to the Aqua Rite Pro/Pro Logic or remote mounted in the vicinity of the
control (restricted by the length of the probe wiring).

Additional Pro Logic Relay: An additional relay is provided for Pro Logic PL-PS-4
and PL-P-4 models operating with software version less than 4.00. Refer to the Pro
Logic manual for instruction on how to determine your software revision. The
additional relay allows the user to add the AQL-CHEM2 or other pH reducing device
to these models. Install this relay only if you have one of these models and intend to
add pH control.

pH Dispense Pigtails: The pH Dispense pigtails provide a plug-in receptacle for the
AQL-CHEM2, AQL-CHEM2-240 or other pH related dispensing device (peristaltic
pumps, solenoid valves, etc.) that will be controlled by the Aqua Rite Pro or Pro Logic.

Various Hardware: The AQL-CHEM includes the necessary tubing, tubing connec­tors and mounting hardware to complete the installation.

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.
