The unit must be mounted so that the bottom of the cabinet is above the overflow rim of the sink. Device shall be installed in a vertical Orientation. A plumbed, dedicated lines is preferred for installation. When a dedicated line is not available, installation shall ensure that no cross-connections between hot and cold water are created, and that atmospheric vaccum breakers integrated into the building water supply are not negatively affected by being under pressure for over 12 continuous hours. introduction package contents: 1. Proportioning unit - ASSE, UPC and CSA certified to ASSE1055 2. Supply tubing 3. Foot valve assembly & weight for each eductor 4. Discharge tube for each eductor 5. Metering tip kit(s) 6. Mounting anchor kit 7. Hose hook for discharge tube(s) - Models with 3.5 or 5 GPM eductors only 8. Instruction sheet 1 installation / maintenance 1. Find suitable place close to water source for unit. Mounting bracket should be installed approx. 5' from the floor. Level bracket and mark holes. Drill 9/32" holes and install mounting anchors and screws in bracket. 2. Remove cabinet cover and hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet and drill 9/32" hole. Install anchor and screw in lower cabinet hole. When mounting unit, do not mount more than 5 feet from the floor. Also, never mount your concentrate container higher than the unit. Keyhole slots are also provided in the cabinet back if the mounting bracket won't be used. 3. Select a metering tip (Refer to tip chart section), and insert into hose barb on eductor body. (Repeat for all eductors.) 4. Supply tube should reach from hose barb on eductor to bottom of the concentrate container. Cut supply tube provided to length required. Slide a ceramic weight over one end of tube and slide a foot valve into the same end of the tube. (Prepare a tube for each eductor.) 5. Push other end of supply tube over the hose barb/metering tip on the eductor. (Repeat for all eductors.) 6. Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINERS REGULARLY FOR CLOGGING: CLEAN IF NECESSARY. 7. A short discharge tube is used with the 1 GPM eductor; minimum tube length is 8 inches (20 cm) for proper operation. Longer tubes (4 feet) are used with a 3.5 GPM eductor. Slide end of tube over eductor discharge outlet. (Repeat for all eductors.) Hooks may be installed on longer tubes to allow discharge tube to conveniently hang from dispenser when not in use. 8. Replace cabinet cover. Guide supply tubes through slots in sides of cabinet cover. Push the sides in, behind the latch holes, to snap the cover in place. The two screws provided may be installed in the holes in the cabinet sides to prevent easy removal of cover. operation 1. Connect water supply hose of at least 3/8" ID to water inlet swivel. (Minimum 25 psi pressure, with water running, is required for proper operation.) Connect opposite end of hose to water supply. Turn water supply on. 2. Purge air from the system by depressing the buttons briefly. There may be some water discharge from the eductor vents until the air is purged. 3. Push button to start flow of desired water/concentrate solution, and hold until supply tube is primed (filled). Then push the button whenever dispensing is desired, and release button to stop flow of solution. If you wish to be able to lock the button in the "ON" position: Depress button and slide button lock up. To unlock, depress button and release. 4. It is essential that the discharge hose not be obstructed. If discharge is restricted, water will flow out the eductor vents. Do not start to operate the dispenser with liquid in the discharge tube. tip chart Metering Tip Selection: The final concentration of the dispensed solution is related to both the size of the metering tip opening and the viscosity of the liquid being siphoned. For water-thin products, the chart at right can be used as a guideline. If product is noticeably thicker than water, consult the Measurement of Concentration procedure below to achieve your desired water-to-product ratio. Because dilution can vary with water temperature and pressure, actual dilution achieved can only be ascertained by using the Measurement of Concentration procedure. The clear, undrilled tip is provided to permit drilling to size not listed should you need a dilution ratio that falls between standard tip sizes. NOTE: A 1 GPM eductor is gray; a 3.5 GPM eductor is yellow. Refer to parts diagram if unfamiliar with names of system components. Measurement of Concentration: You can determine the dispensed water-to-product ratio for any metering tip size and product viscosity. All that is required is to operate the primed dispenser for a minute or so and note two things: the amount of dispensed solution, and the amount of concentrate used in preparation of the solution dispensed. The water-to-product ratio is then calculated as follows: Dilution Ratio (X:1) where X = Amount of Mixed Solution -- Amount Concentrate Drawn Amount of Concentrate Drawn Dilution Ratio, then, equals X parts water to one part concentrate (X:1). If the test does not yield the desired ratio, choose a different tip and repeat the test. Alternative methods to this test are 1) pH (using litmus paper), and 2) titration. Contact your concentrate supplier for further information on these alternative methods and the materials required to perform them.

Put clamp on tube or replace tube if brittle * In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove an eductor located in the cabinet, firmly grasp water valve and unscrew the eductor. Replace in same manner. Alternatively, a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate. warranty Limited Warranty Seller warrants solely to Buyer the products will be free from defects in material and workmanship under normal use and service for a period of one year from the date of completion of manufacture.
