Principles of Operation The Aqua-Lab EVO was designed to meet the application requirements of the standard roll-over automatic car wash with an available pump room to store chemical and equipment. The system is set-up so that all that is required from the car wash controller is an output signal for each valve. The EVO electrical control box uses that signal to open both the 3.5 watt air solenoid valves and to start the pump.
Startup Pump Priming Instructions 1. Pull the pump outlet line at the manifold quick-connect. Open ball valve and direct toward a drain or container to remove the majority of the air from the pump until a steady stream of water is flowing (approx. 1 min). 2. Start the pump using a command from the controller. Ensure that pump rotation is correct as indicated by the arrow on the bottom of the pump and that 200 psi can be reached. o If pump cannot regulate to 200 psi.

Application Optimization (repeat for each application) • • • • • • • Application too wet o Increase air o Reduce injector size (decreases water) o Increase metering tip (increases chemical) Application too dry o Decrease air o Increase injector size (increases water) o Decrease metering tip (decreases chemical) Nozzle sputters o Decrease air o Decrease nozzle(s) and/or size used on arch o Increase injector size (increases water) Too much chemical used o Decrease metering tip o Decrease metering tip a
Recommended Maintenance The recommended service and maintenance on the AQUA-LAB System are as follows.
Troubleshooting Injector Vacuum Check (for troubleshooting injectors) 1. At the Chem-Flex injector, remove the chemical feed line from the injector hose barb. 2. Attach the tubing of the vacuum gauge to the Chem-Flex hose barb 3. With the pump(s) on, manually activate the chemical that is to be tested at the main car wash control cabinet. An injector that is working properly will have a reading greater than or equal to (≥) 20 in Hg 4.
Air Operated Valve Replacement 1. Shut off the ball valve to Hydra-Cannon manifold 2. Disconnect air line from front of valve 3. Unscrew quick connect fitting by hand (DON’T LOSE BLACK WASHER) 4. Unscrew valve assembly from the Hydra-Cannon manifold 5. Screw new valve into manifold until hand tight and threaded pilot port is facing forward 6. Remove the cap from pilot port and thread in quick connect fitting to front of valve – Hand Tight ONLY 7. Push air line back into fitting 8.
Pump Issues Problem Potential Causes Solutions Pump Operates, but only delivering 100150 psi Incorrect Motor Rotation Reverse rotation by interchanging two leads Pump not Primed Missing 1 of 3 phases Inadequate water supply See Priming Instructions Wire according to diagram Check pressure on inlet side of pump to be sure positive pressure is maintained Replace with larger piping Make sure connections are tight Replace worn parts or entire pump, clean parts if required Make sure constant control volta
Pressure Regulator Issues Problem System won’t regulate up to 200 psi Potential Causes Solutions Pump not primed Debris in regulator Motor rotation incorrect Opening too many valves at once Follow priming instructions Remove regulator and clean out debris Verify rotation System is limited by size of pump and size of injectors, increase flow by adding secondary pumps or reduce size / number of injectors open Replace check valve Replace regulator Replace Pump Defective check valve (if applicable) Defect
