Hydro Systems 3798 Round Bottom Road, Cincinnati, OH 45244 Phone: (513) 271-8800 Fax: (513) 271-0160
Installation and Operation:
1. Find suitable place close to water source for unit. Mounting bracket should be installed approx. 5' from the floor. Level
bracket and mark holes. Drill 9/32" holes and install mounting anchors and screws in bracket.
2. Remove cabinet cover and hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet and drill 9/32" hole.
Install anchor and screw in lower cabinet hole. When mounting unit, do not mount more than 5 feet from the floor. Also, never
mount your concentrate container higher than the unit. Keyhole slots are also provided in the cabinet back if the mounting
bracket won't be used.
3. Select metering tips (up to 4) for the 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.
4. 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.
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
REGULARLY FOR CLOGGING: CLEAN IF NECESSARY.
7. 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. Do not remove the flooding rings from inside the tubes. Slide end of tube
with flooding 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. Push the sides in, behind the latch holes, to snap the cover in place. The two screws provided may
be installed in the holes in the cabinet sides to prevent easy removal of cover.
9. 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.
10. 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.
11. 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. 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.
12. 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.
Troubleshooting Chart:
* 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, fi rmly 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 fl ush the unit by
drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.

Metering Tip Selection:
The fi nal 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.
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 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.
