********************************************************* NOTE*********************************************
WEAR
protective clothing and eyewear when dispensing chemicals or other materials.
ALWAYS
observe safety and handling instructions of the chemical manufacturers.
ALWAYS
direct discharge away from you or other persons or into approved containers.
ALWAYS
dispense cleaners and chemicals in accordance with manufacturer's instructions. Exercise
CAUTION when maintaining your equipment.
KEEP
WEAR
equipment clean to maintain proper operation.
ALWAYS
re-assemble equipment according to instruction procedures. Be sure all components are
rmly screwed or latched into position.
ATTACH
only to tap water outlets (85 PSI maximum).
NOTE
If the unit is used to ll 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 over ow rim of the sink.
a. Clean* or replace with valve parts kit
b. Make sure magnet moves freely.
c. Remove button and clean cabinet/button
to remove any dirt lodged in slide recess
a. Put 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 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.

Installation and Operation:
1. Find suitable place close to water source for unit. Mounting bracket should be installed approx. 5' from oor. Level bracket
& mark holes. Drill 9/32" holes & install mounting anchors and screws in bracket. Drill holes for the three wall anchors with
a 5/16" drill bit, 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 cabinet back over screw heads, tighten screws, then install bottom
screw. Do not mount more than 6 feet (1.8 meters) above the bottom of the concentrate container, nor below the highest
concentrate level (never mount your concentrate higher than the proportioner).
2. Hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet & drill 9/32" hole. Install anchor and
screw to lower unit hole. When mounting unit do not mount any higher than 5 feet from the oor. Also, never mount your
concentrate container higher than the unit.
3. Select a metering tip, and insert into hose barb on eductor body. (Repeat for all eductors.)
4. Cut supply tubing provided into separate supply tubes for each product to be dispensed. Supply tubes should reach from
hose barb on eductor to bottom of the concentrate container. Slide a ceramic weight over one end of tube and slide a foot
valve into the same end of the tube. (Prepare a tube for each eductor.)
5. 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.)
6. Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINERS
PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY.
7. A short discharge tube is used with the 1GPM eductor; minumum tube length is 8 inches (20cm) for proper operation.
Longer tubes (4 feet) are used with a 3.5 GPM eductor. Do not remove the ooding rings from inside the tubes. Slide
end of tube with ooding ring over eductor discharge outlet. (Repeat for all eductors.) Hooks may be installed on longer
tubes to allow discharge tube to conveniently hang from dispenser when not in use.
8. Replace cabinet cover. Hook two bottom catches, and swing up to snap onto latch. A
Clip or bend
screw provided may be installed in the hole on top to prevent easy removal of cover.

tube is primed ( lled). Then push the button whenever dispensing is desired, and
release button to stop ow of solution. If you wish to be able to lock the button in the
"on" position: clip or bend the two tabs behind the lower front portion of the button (see
diagram). This allows the button to be fully depressed and allows it to latch in the "on"
position. To unlock, pull the button out.
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 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 size not listed should
you need a dilution ratio that falls between
standard tip sizes.

Measurement of Concentration:
You can determine the dispensed waterto-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.
