Installation
Installation
Installing the AQL-CHEM2 or AQL-CHEM2-240 requires the following steps:
• Mount CO
2
tank using commercially available straps
• Attach the solenoid valve to the CO
2
tank
• Install the PVC check valve injector to the pool's return plumbing
• Plug the solenoid valve into the pigtail of the Aqua Rite Pro or Pro Logic pool control
• Configure the Aqua Rite Pro or Pro Logic to control the AQL-CHEM2(-240)
This manual assumes that the Hayward AQL-CHEM Chemistry Kit and the pH Dispense Pigtail
(included with AQL-CHEM) have already been installed. If not, this will need to be performed prior to
installation. Refer to the AQL-CHEM manual for installation instructions.
Mount CO
2
tank
Mount the CO
2
tank in an easily accessible location. Straps or brackets can be purchased from the
tank supplier and must be used for a secure installation.
Attaching the solenoid valve
The solenoid valve attaches to the CO
2
tank much like an outdoor gas grill attaches to a propane
tank. With the tank valve off, insert the included nylon washer and screw the fitting of the AQL-
CHEM2(-240) solenoid valve on to the CO
2
tank. If the nylon washer is lost or destroyed, a spare is
provided. Keep the tank's valve off until the entire installation is complete.
