The HL-CHEM is an ORP and pH sensing kit that is offered as an accessory for all OmniLogic® pool
automation controls. With the HL-CHEM, the OmniLogic can provide a fully integrated chemistry
solution for your pool. The HL-CHEM continuously tests the pool's sanitization and pH levels allowing the OmniLogic 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 HL-CHEM comes with two pigtails (120 VAC and 240 VAC) 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 (120 VAC) and AQL-CHEM2-240 (240 VAC)
CO2 dispense kit that plugs into the pigtail and will reduce the pool's pH level by injecting CO2 into
the pool water. he HL-CHEM is an ORP and pH sensing kit that is offered as an accessory for all OmniLogic® pool
