Hayward Pro Logic Model: AQL-CHEM-3 Installation and Operation - Page 3

Before You Begin Compatibility The AQL-CHEM-3-120 (120VAC) and AQL-CHEM-3-240 (240VAC) are compatible with all Hayward Aqua Rite Pro and Pro Logic pool controls using an AQL-CHEM Sense & Dispense system. The AQL-CHEM-3 is not compatible with Aqua Rite or Aqua Logic controls. Description The AQL-CHEM-3 is an automatic acid dispensing system which utilizes a Stenner 45M Series acid pump and 15 gallon tank to lower the pH level in your swimming pool. When used with a Hayward AQL-CHEM ORP and pH Sensing Kit, the Hayward Aqua Rite Pro or Pro Logic pool control will measure the pool's pH and, if too high, automatically enable the AQL-CHEM-3 to dispense muriatic acid into the pool until the pH reaches the desired level. What's included Ensure that the following contents have been included in the AQL-CHEM-3 box: • Stenner 45M Series acid pump and 15 gallon tank containing: 3 Connecting nuts 3 Ferrules 1 Weighted strainer (pre-installed) 1 20' Roll of suction/discharge tubing 1/4" UV black 1 Spare pump tube 1 Injection fitting (not used, may be discarded) 1 Mounting bracket (pre-installed) 1 Rain roof 1 Stenner Installation Manual • 1 Flow Indicator • 2 Injector Valves (short injector valve is not used and can be discarded) • 1 Hose clamp • 1AQL-CHEM-3 Manual Safety Refer to the Stenner manual included with the dispenser for specific safety information related to that product. Because the AQL-CHEM-3 system uses muriatic acid, refer to the additional information below: • Always use the proper dilution in the acid feed system (4:1 dilution of 20° Baume hydrochloric acid 31.45% by weight or equivalent). • To prevent violent boiling and splashing, ALWAYS ADD ACID TO WATER; never add water to acid to dilute it. Some use the rhyme "do as you oughta- add acid to water". • Strictly follow the acid vendor's safety and handling protocols including hand, body and eye protection when transferring or handling acid. • Fill the 15 gallon tank to the following levels: 5 gallons of 4:1 solution for pools up to 15,000 gallons of water 10 gallons of 4:1 solution for pools up to 30,000 gallons of water 15 gallons of 4:1 solution for pool above 30,000 gallons of water This limits the available acid in the event that equipment malfunctions and empties the tank into the pool or spa. 9 2
