Description
The AQL-CHEM2 is a 120 VAC CO
2
dispense kit designed for use with a Hayward Aqua Rite Pro
chlorinator or Pro Logic pool control. The AQL-CHEM2-240 is identical to the AQL-CHEM2, but
uses 240 VAC. When used with the AQL-CHEM sensing kit, the AQL-CHEM2(-240) solves the
problem of how to provide low cost pH control for backyard pools without having to handle acid.
The AQL-CHEM2(-240) is designed to install on a standard CO
2
tank and wire directly to the Aqua
Rite Pro or Pro Logic. Using the AQL-CHEM sensing kit, the Aqua Rite Pro or Pro Logic will sense
the pH level and if needed, the AQL-CHEM2(-240) will inject CO
2
into the pool water. CO
2
is mildly
acidic when dissolved in water and will lower the pool's pH slowly without the safety or health
concerns normally associated with harsher acids.
What's Included
The AQL-CHEM2 and AQL-CHEM2-240 include the following:
• Pressure reducing regulator preset at 50 psi output
• 110 VAC (AQL-CHEM2) or 240 VAC (AQL-CHEM2-240) solenoid valve with 6' power cord
• Nylon washer and spare (only use one)
• 15' of black UV resistant flexible tubing
• PVC check valve injector

information and availability
The AQL-CHEM2(-240) kit requires the use of CO
2
which is supplied in cylinders that are readily
available from various sources. CO
2
storage tanks are offered in a variety of sizes. Hayward recom-
mends the use of 20 pound cylinders for most residential pool applications. The AQL-CHEM2(-240)
uses a standard fitting for these tanks. CO
2
can be easily found at local and national welding supply
or beverage companies. A quick search on the web with the keywords “CO
2
supply” will yield many
companies, some with hundreds of branch/store locations nationwide.
