only to water tap outlets (25 psi Minimum, 85 psi Maximum and Maximum water temperature 120° F).
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
1. Hold unit up to wall and drill holes for the wall anchors with a 9/32” drill. Install mounting anchors, and then install screws
into top two anchors. Slide key holes at top of dispenser over screw heads. Install bottom two screws through holes in
cabinet. Tighten all screws. Do not mount more than 6 ft. (1.8 m) above bottom of concentrate container, nor below the
highest concentrate level (never mount your concentrate higher than the dispenser). Turn ball valves so they are in a horizontal
position (pointing left and right).
2. Select metering tips (see next section) and insert a tip into each hose barb on the eductor bodies.
3. Suction tubes should reach from hose barbs on eductors to bottoms of concentrate containers. Cut tube supplied to lengths
required. (There is enough tube for 7 feet of tube per eductor.) Slide a weight over one end of each suction tube and slide a
foot valve into the same ends of the tubes.
4. Slip open ends of suction tubes over the hose barbs/metering tips on the eductors (one at each side).

installation and operation (continued)
5. A long (4ft.) discharge tube is used with 4 GPM (yellow) eductors. Do not remove flooding rings from insidethe tubes. Slide
end of tube with flooding ring over discharge outlet.
6. Install discharge tubes over inner discharge tubes. Put the ends of the tubes into the appropriate sink compartments.
7. Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINER
PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY.
Operation
1. Connect water supply hose of at least ½” ID to water inlet swivel. (Minimum 25 psi pressure, with water running, is required for
proper operation.) Connect other end of hose to water supply. Turn water supply on.
2. Purge air from the system by opening the ball valves briefly. (Ball valves will be in vertical position -- pointing up and
down -- when open.) There may be some water discharge from the eductor vents until the air is purged.
3. Open one ball valve to start flow of desired water/concentrate solution, and run unit until supply tube is primed (filled). Repeat
priming operation for other ball valve. Then, open ball valves when dispensing is desired. Close ball valves to stop flow of
solution.
4. It is essential that the discharge hose not be obstructed. If discharge is restricted, water will fl ow out the eductor
vents.
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 tempera-
ture 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.

Problem Cause Solution
1. No discharge a. No water a. Open water supply
b. Clogged water inlet strainer c. Disconnect inlet water line and clean strainer
c. Eductor clogged e. Clean* or replace
2. No concentrate draw a. Clogged foot valve a. Clean or replace
b. Metering tip or eductor has scale build-up b. Clean (descale)* or replace
c. Low water pressure c. Minimum 25 psi (with water running) required
to operate unit properly
d. Discharge tube and/or flooding ring not in place d. Push tube firmly onto eductor discharge
hose barb, or replace tube if it doesn‘t have a
flooding ring
e. Concentrate container is empty e. Replace with full container
f. Inlet hose barb not screwed into eductor tightly f. Tighten, but do not overtighten
3. Excess concentrate draw a. Metering tip not in place a. Press correct tip firmly into barb on eductor
b. Chemical above eductor b. Place concentrate below eductor
* 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 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 concentrate container and put suction tube
into concentrate.
