Frequently Asked Questions
What is the difference between this (AC005) and a standard CO2 kit?
The AC005 is described as a "high output" CO2 system, indicating it's rated for higher CO2 flow rates than a standard kit — making it suitable for larger commercial pools with greater pH control demand. A standard CO2 kit would be sized for smaller pools or lower-demand applications.
Does this work with any pH controller?
Yes. The solenoid valve accepts a control signal from any compatible pH controller — including Hayward CAT series, HCC series, and other brands that support CO2 feed equipment. The controller's CO2 output signal activates the solenoid to dose CO2 when pH rises above the setpoint.
Is the CO2 tank included?
No. The CO2 tank must be sourced locally from a CO2 gas supplier. Standard industrial or beverage-grade CO2 cylinders are typically used — your local supplier can advise on the appropriate tank size for your pool's demand.
