installation and operation

Installation

1. Find a suitable place close to a water source for the 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 the 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 an anchor and screw in the lower cabinet hole. When mounting the unit, do not mount it 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 metering tips (up to 4) for the selector valve. (See next two sections.) Push each tip firmly into a separate hose barb extending from the selector valve. A tip with no hole (clear plastic) can be used to block any valve port being used. This may be used for dispensing water only.) Select and install a metering tip for the single product educator (right side) in the same manner.
4. Cut tubing is provided into separate supply tubes for each product to be dispensed (tubing allows 7 feet of tube per product). Supply tubes should reach from hose barbs on the selector valve body and eductor to bottom of concentrate containers Slide ceramic weights over one end of each tube and slide foot valves into the same ends of the tubes.
5. Slip other end of the supply tube through an opening in either side of the cabinet and push 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 1.0 GPM educator; the minimum tube length is 8 inches (20cm) for proper operation. Longer tubes (4 feet) are used with a 3.5 GPM educator. Do not remove the flooding rings from inside the tubes. Slide end of tube with flooding ring 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. 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 pressing 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 the button to stop the flow of the 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 educator vents. Do not start to operate the dispenser with liquid in the discharge tube.

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, con- sult 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 1.0 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:

APPROXIMATE DILUTIONS

AT 40 PSI FOR WATER-THIN PRODUCTS (1.0 CP)

Tip Color| Orifice Size| Ratio (per Eductor Flow)

1.0 GPM           3.5 GPM

No Tip| .187| 2.6:1| 4:1
Grey| .128| 2.6:1| 4:1
Black| .098| 2.5:1| 5:1
Beige| .070| 3:1| 8:1
Red| .052| 5:1| 13:1
White| .043| 7:1| 22:1
Blue| .040| 9:1| 26:1
Tan| .035| 11:1| 34:1
Green| .028| 17:1| 52:1
Orange| .025| 19:1| 64:1
Brown| .023| 22:1| 71:1
Yellow| .020| 32:1| 102:1
Aqua| .018| 39:1| 128:1
Purple| .014| 64:1| 213:1
Pink| .010| 128:1| 447:1

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.

 | g. Clogged water inlet strainer| • Disconnect inlet water and clean strainer
 | h. Air leak in chemical pick-up tube| • Put clamp on tube or replace tube if brittle
 | i. Selector out of position| • Assure selector is in position desired
3. Excess concentrate draw| a. Metering tip not in place| • Press correct tip firmly into barb on eductor
 | b. Chemical above eductor| • Place concentrate below the eductor
4. Failure of unit to turn off| a. Water valve parts dirty or defective| • Clean or replace with valve parts kit
 | b. Magnet doesn’t fully return| • Make sure magnet moves freely
 | c. Push button stuck| • Remove the button and clean the cabinet/button to remove any dirt lodged in the slide recess
5. Excess foaming in discharge| a. Air leak in pick-up tube| • Put a 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 the water valve and unthread 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 the solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace the concentrate container and put the suction tube into the concentrate.
