Installation/Maintenance:
1. Find suitable place close to a water source for unit. Remove wall bracket from packaging, place level on wall and mark (3) mounting
holes. Drill (3) 5/16” holes and install anchors in wall. Secure wall bracket to wall with screws and washers provided.
NOTE: The distance from the top of the wall bracket to the top of the cabinet is 1/8”.
2. Place the cabinet onto the wall bracket aligning the tabs with the slots in the top of the cabinet. Also ensure the central snap on top
of the wall bracket engages the cabinet. Mark the wall using the (2) lower holes, as guides, then remove cabinet from wall. Drill (2)
5/16” holes and install anchors in wall.
3. Select metering tips (up to four) 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 not being used for chemical.
(This may be used for dispensing water only). (See Metering Tip Chart below)
4. Cut supply tube provided into separate supply tubes for each product dispensed. Use“Y” fittings to connect both high and low flow
eductor to single container. Supply tubes should reach from hose barb on educator to the bottom of container for easy replacement
of chemical. (See diagram page 3.) Prepare a tube for each barb of select valve. Supply tube routing to lower containers should pass
through circular notch in the shelf back. NOTE: ARROW ON CHECK VALVES SHOULD BE POINTED TOWARD THE EDUCTOR.
5. 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 3.5GPM eductor. Do not remove the flooding rings from inside the tubes. Install hose hook on longer tube to
allow discharge tube to conveniently hang from dispenser when not in use.
6. 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. Maximum Pressure 85 PSI, Maximum water Temperature 120° F.)
7. Place the cabinet back onto the wall bracket (see #2) and secure the bottom of the cabinet to the wall with the screws provided.
NOTE: IT IS REQUIRED THAT THE BOTTOM (2) SCREWS BE INSTALLED.
8. Install optional drip tray by aligning the four tabs on the tray with the four slots in the lower cabinet and push down.
9. If maintenance is required, remove the medallion cover from the unit by pushing inward on the two snap features located inside near
the bottom of the medallion and rotate upwards. These snaps can be accessed by unlocking and opening the doors (See Page 3).
10. Replace medallion cover. Insert the upper medallion tabs into the cabinet slots and swing down to engage lower medallion snaps
on the inside of the cabinet. Ensure selector knobs are properly aligned. (See Diagram Page 3).
Operation:
1. Connect opposite end of water inlet hose to water supply. Turn on water supply.
2. Purge air from the system by depressing the buttons briefly. There may be some water discharge from the eductor vents until the air
is purged.
3. To operate button fill units, depress button to dispense product, release button to stop flow. IF YOU WISH TO BE ABLE TO LOCK
THE BUTTON IN THE “ON” POSITION: Depress button and slide button lock up, TO UNLOCK, DEPRESS BUTTON AND RELEASE.

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.
NOTE: A 1 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 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.

* 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.
