Product Usage Instructions

Installation

1. Select a metering tip for each eductor and insert it into the hose barb on the eductor body.
2. Ensure the supply tube reaches from the hose barb on the eductor to the bottom of the concentrate container. Cut the tube to the required lengths if using multiple eductors. Slide the ceramic weight and foot valve into one end of the tube.
3. Thread the open end of the supply tube through a cabinet opening and push it over the hose barb/metering tip on the eductor.
4. If necessary, use the Foam/Froth Reducing Tube with the 1 GPM educator. Warm the tube end for easy installation. Attach the outer discharge tube (ODT) to the eductor outlet.
5. Use short discharge tubes for 1 GPM educator and longer hoses for 3.5 GPM eductors. Secure longer tubes with clamps and hooks provided.
6. Place the foot valve ends of supply tubes into concentrate containers and periodically check and clean the foot valve strainer for clogging.

Operation

1. Purge air from the system by briefly depressing the buttons. Water discharge may occur from the eductor vents until all air is purged.

(FAQ)

• Q : What should I do if I encounter excessive foam during operation?
• A: If you encounter excessive foam during operation, ensure you have properly installed the Foam/Froth Reducing Tube. If the issue persists, check if your chemical solution is prone to foaming or consult the manufacturer for guidance.

Safety Precautions

WARNING! Read and fully understand the user manual before operating this product.

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 the 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 the 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

f the unit is used to fill a sink, or the discharge hose can be placed into a sink. 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 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 pressure for over 12 continuous hours.

installation and operation

Installation

1. Remove cabinet covers. Drill holes for the three wall anchors with a 9/32” drill, using the cabinet back as a template for proper spacing of the mounting screws. Install mounting anchors, and then screws in top two anchors. Slide key holes in the cabinet back over screw heads. Tighten the screws and install a third (bottom) screw. Do not mount more than 6 ft. (1.8 m) above the bottom of the concentrate container, nor below the highest concentrate level (never mount your concentrate higher than the Streamline unit).
2. Select a metering tip for each eductor (see next section) and insert the tip into the hose barb on the eductor body.
3. The supply tube should reach from the hose barb on the eductor to the bottom of the concentrate container. If using more than one educator, cut the supply tube provided to the lengths required. Slide ceramic weight over one end of the tube and slide the foot valve into the same end of the tube.
4. Slip the open 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.
5. If required, the optional Foam/Froth Reducing Tube can slide on the end of the grey 1 GPM eductor. Push the tube as far as possible. Warm the end of the tube for easy installation. Push the end of the outer discharge tube (ODT) onto the barb of the eductor outlet. If installed, slide it over the Foam/Froth Reduction Tube. This tube will reduce the amount of foam that may occur with some chemicals. It is not needed if your chemical does not foam.
6. A short discharge tube is used with 1 GPM educator; the minimum hose length is 7 in. (18 cm) for proper operation. Longer (4 ft.) hoses are used with 3.5 GPM eductors. Clamps for securing the 3.5 GPM tubes are provided. Hooks are provided to allow longer discharge tubes to conveniently hang from the side cabinet openings. Gently twist the hook onto the tube after starting the tube through the hook.
7. Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK THE FOOT VALVE STRAINER PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY. Replace cabinet cover and screws.

Operation

1. Connect the water supply hose of at least ½” ID to the water inlet swivel. (Minimum 25 psi pressure, with water running, is required for proper operation.) Connect the other 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 educator 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 the solution. Optional twist-to-latch buttons are available for continuous dispensing without holding

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.

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 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 1.0 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 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.

b.| High water pressure| b.| Install pressure regulator if the 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 the water valve and unthread 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 the concentrate container and put a suction tube into the concentrate.
