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, automati-
cally 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 Hose clamp
•
1 AQL-CHEM-3 Manual
Safety
Refer to the Stenner manual included with the dispenser for specific safety informa-
tion 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 emp-
ties the tank into the pool or spa.
