Hayward Goldline CO2 Dispensing Kit For AquaRite and ProLogic AQL-CHEM2

The AQL-CHEM2 is a 120VAC CO2 dispense kit designed for use with a Goldline Aqua
Rite Pro chlorinator or Pro Logic swimming pool control. The AQL-CHEM2-240 is identical to
the AQL-CHEM2, but uses 240VAC. 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 swimming pools without having to handle acid. The AQL-CHEM2(-240) is designed to
install on a standard CO2 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 CO2 into the swimming pool water. CO2 is
mildly acidic when dissolved in water and will lower the swimming pool’s pH slowly without the
safety or health concerns normally associated with harsher acids.

CO2 information and availability: The AQL-CHEM2(-240) kit requires the use of CO2 which is supplied in cylinders that
are readily available from various sources. CO2 cylinders are offered in a variety of
sizes. Goldline recommends the use of 20 pound cylinders for most residential swimming pool
applications. The AQL-CHEM2(-240) uses a standard fitting for these tanks. CO2 can
be easily found at local and national welding supply or beverage companies. A quick
search on the web with the keywordsCO2 supplywill yield many companies, some
with hundreds of branch/store locations nationwide.
