Safety Precautions
WARNING! Please read precautions thoroughly before operation. Must meet all applicable local codes and regulations.
THANK YOU FOR YOUR INTEREST IN OUR PRODUCTS
Please use this equipment carefully and observe all warnings and cautions.
WEAR protective clothing and eyewear when dispensing chemicals or other materials or when working in the vicinity of all chemicals, filling or emptying equipment, or changing metering tips.
ALWAYS observe safety and handling instructions of the chemical manufacturer.
direct discharge away from you or other persons or into approved containers.
dispense cleaners and chemicals in accordance with manufacturer’s instructions. Exercise CAUTION when maintaining your equipment.
reassemble equipment according to instruction procedures. Be sure all components are firmly screwed or latched into position.
KEEP equipment clean to maintain proper operation.
ATTACH only to water tap outlets (25 psi Minimum, 85 psi Maximum and Maximum water temperature 120° F).
NOTE If the unit is used to fill a sink, or the discharge hose can be placed into a sink, the unit must mounted be so the bottom of the cabinet is above the overflow rim of the sink.
Device shall be installed in a vertical orientation.
A plumbed, dedicated line 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 presssure for over 12 continuous hours.

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 can be used as a guideline. If product is noticeably thicker than water, consult the Measurement of Concentration procedure 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 of 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.

| e. Concentrate container is empty | e. Replace with full container | |
| f. Clogged water inlet strainer | f. Disconnect inlet water line and clean strainer | |
| g. Inlet hose barb not screwed into eductor tightly | g. Tighten, but do not overtighten | |
| h. Air leak in pick-up tube | h. Put clamp on tube or replace tube if brittle | |
| i. For AirGap version, no flooding feature in the eductor | i. Replace eductor if all other items in problem 2 are ok | |
| 3. Excess concentrate draw | a. Metering tip not in place b. Chemical above eductor | a. Press correct tip firmly into barb on eductor b. Place concentrate below eductor |
| 4. Failure of unit to turn off | a. Water valve parts dirty or defective | a. Clean or replace with valve parts kit |
| b. Magnet doesn‘t fully return | b. Make sure magnet moves freely replace spring if short or weak | |
| c. Push button stuck | c. Remove button and clean cabinet/button to remove excess dirt lodged in slide recess | |
| 5. Excess foaming in discharge | a. Air leak in pick-up tube | a. Put clamp on tube or replace tube if brittle |
| b. For 1 GPM AirGap version, excessive air mixed with chemical | b. Put foam reduction tube on eductor nozzle | |
| 6. Water Discharge from AirGap Backflow Device | a. Restricted discharge hose | a. Be sure discharge hose is not immersed, kinked or elevated. Be sure there is no liquid in the disharge hose when begining to operate dispenser. |
| b. High water pressure | b. Install pressure regulator if flowing water pressure exceeds 85 psi. |
* 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.
