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 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 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

Remove the cabinet screws and cover. Drill holes for the wall anchors with a 9/16” drill, using the cabinet back as a template for proper spacing of the mounting screws. Install the anchors. Install screws into the top two anchors. Slide the key holes in the cabinet back over the screw heads and tighten the screws. Install the third (bottom) screw and tighten. Do not mount more than 6 ft.(1.8 m) above the bottom of the chemical container nor below the highest concentrate level (never mount your concentrate higher than the Streamline unit).
Select metering tips (up to 4) for each 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 eductor (right side) in the same manner.
Cut tubing 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.
Slip other end of 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.)
Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINERS PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY.
If required, the optional Foam/Froth Reduction Tube can slide on the end of the grey 1 GPM eductor Warm the end of the tube for easy installation. This tube will reduce the amount of foam that may occur with some chemicals. It is not needed if your chemical does not foam.
A short discharge tube is used with the 1GPM eductor; minimum tube length is 8 inches (20cm) for proper operation. Longer tubes (4 feet) are used with a 3.5 GPM eductor. Hooks may be installed on longer tubes to allow discharge tube to conveniently hang from dispenser when not in use.
Replace the cabinet cover and screws.

Operation

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.
Push button to start flow of desired water/concentrate solution, hold the button until the unit supply tube is primed (filled). Optional twist to latch buttons are available for continuous dispensing without holding the button.
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. Optional twist-to-latch buttons are available for continuous dispensing without holding button.
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.

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 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 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.
