installation/maintenance

1. Find a suitable place close to the water source for unit. The 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 the bracket.
2.  Remove cabinet cover and hang the cabinet on the bracket. Mark hole for lower cabinet screw. Remove the cabinet and drill a 9/32” hole. Install anchor and screw in lower cabinet hole. When mounting the 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 it into the hose barb on the eductor body. (Repeat for all eductors.)
4. The supply tube should reach from the hose barb on the educator to the bottom of the concentrate container. Cut supply tube provided to the length required. Slide a ceramic weight over one end of the tube and slide a foot valve into the same end of the tube. (Prepare a tube for each educator.)
5. Push the other end of the 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 educator; the minimum tube length is 8 inches (20 cm) for proper operation. Longer tubes (4 feet) are used with a 3.5 GPM educator. Slide end of tube over eductor discharge outlet. (Repeat for all eductors.) Hooks may be installed on longer tubes to allow the discharge tube to conveniently hang from the dispenser when not in use.
8. Replace cabinet cover. Guide supply tubes through slots in the sides of the 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 the water supply hose of at least 3/8” ID to the water inlet swivel. (Minimum 25 psi pressure, with water running, is required for proper operation.) Connect the opposite end of the hose to the water supply. Turn the 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 the button to start the flow of desired water/concentrate solution, and hold until the supply tube is primed (filled). Then push the button whenever dispensing is desired, and release the button to stop the flow of solution. If you wish to be able to lock the button in the “ON” position: Depress the button and slide the button lock up. To unlock, depress the button and release.
4. It is essential that the discharge hose not be obstructed. If the 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 the 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 a size not listed should you need a dilution ratio that falls between standard tip sizes.
NOTE: A 1 GPM eductor is grey; a 3.5 GPM eductor is yellow. Refer to the parts diagram if unfamiliar with the 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

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.

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 the 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 the concentrate.
