Hayward Pro Logic Model: AQL-CHEM-3 Installation and Operation - Page 6

Setup of Stenner pump and tank Refer to the included Stenner manual for specific information on installing, securing and use of the pump and tank. Install the Feed Tube and Injector assembly into the return pipe 1. Drill 7/16" hole on the UNDERSIDE of the pool's return pipeAFTER the electrolytic cell and flow switch. Be sure there is at least 10" of clearance under the pipe before drilling. Clear out any PVC shavings and make sure there are no sharp edges within the hole. OPTIONAL: The injector assembly (saddle fitting, check valve, short length of feed tube, and flow indicator) should be installed on the underside of the plumbing to ensure that the flow indicator maintains a vertical orientation. If there is not enough space underneath the plumbing, the assembly may be mounted on the top or side of the plumbing as long as the flow indicator is in a position that has enough feed tube length to allow it to be oriented vertically when flow reading is required. 2. Connect the Flow Indicator to the Injector NOTE: Two injector valves are included with the AQL-CHEM-3. Discard the shorter injector as it does not included a flow-check system and must not be used. The correct injector has a flow direction indicator as shown in the diagram below. Cut a 2" piece of 1/4" tubing to connect the injector to the flow indicator. With the fittings loose, insert the tubing firmly into each component and handtighten fittings until tubing is secure. Note that the flow Indicator and the injector are directional and must be assembled in the proper orientation according to the diagram below.

Fasten the Injector assembly to the return pipe and install the Feed Tube Fasten the injector assembly to the return pipe by pushing the injector fitting into the 7/16" hole. Tighten the hose clamp until the assembly is snug against the return pipe. Do not overtighten. Cut the 20' feed tube to the desired length. Connect one end of the feed tube to the injector assembly by firmly pushing it into the flow indicator and handtightening the fitting. Connect the other end of the feed tube to the output side of the Stenner pump as shown below. Pool Return Pipe Stenner pump Input Output Injector Assembly Feed Tube Fill the tank Fill the tank with acid based on the guidelines provided in this manual and the Stenner manual. Use a diluted mixture of 4 parts water to 1 part Muriatic acid (20º Baume hydrochloric acid 31.45% by weight). Always add acid to water, and do so slowly. 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 Connect the AQL-CHEM-3 to the Aqua Rite Pro or Pro Logic control Plug the Stenner pump's linecord into the pH Dispense pigtail of the Aqua Rite Pro or Pro Logic. This pigtail is provided with the AQL-CHEM. If the pigtail isn't already installed, refer to the AQL-CHEM product manual for installation instructions. Program the Aqua Rite Pro or Pro Logic The pool control must now be programmed to operate the AQL-CHEM-3. Refer to the Aqua Rite Pro or Pro Logic operation manual for specific programming instructions. 6
