THANK YOU FOR YOUR INTEREST IN OUR PRODUCTS
Hydro Systems manufactures quality chemical proportioners. Please use this equipment carefully and observe all
warnings and cautions.
**************************************************************** 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
equipment clean for proper operation.
WEAR
protective clothing and eyewear when working in the vicinity of all chemicals, filling or emptying
equipment or changing metering tips.
ALWAYS
re-assemble equipment according to instruction procedures. Be sure all components are firmly
screwed or latched into position.
ATTACH
only to tap water outlets (85 PSI maximum).
Through proper care and maintenance, this equipment will serve your toughest cleaning jobs.
Installation:
1. Mount the unit in a level position on the side of a reservoir. The U-clamp may be repositioned or removed as necessary.
2. Install a minimum 3/8" ID water hose between the inlet threads and the water spigot. Minimum water pressure required
to properly operate the proportioner is 25 PSI (flowing).
3. Attach the end of the discharge tube with the clamp and flooding ring to the discharge barb on the eductor.
4. Insert the foot valve end of the suction tube into the concentrate container. (The level of the concentrate must be below
the level of the eductor, or the proportioner will continue to siphon concentrate after it is turned "off".)
5. Select a metering tip (see next two sections) and screw it into the suction stub on the eductor body.
6. Slide the open end of the suction tube over the suction stub.
7. Adjust the bead chain length to position the float at the desired level of solution. To prevent foaming, be certain that the
solution level will always be above the point of discharge. Be sure float mechanism is not hampered by water turbulence
caused by discharging solution. It may be necessary to baffle the float from the discharge in order for the unit to work
properly.
Metering Tip Selection:
The final concentration of the dispensed liquid is related to both the size of the metering tip opening (orifice) and the viscosity
of the liquid being siphoned. If product viscosity is noticeably greater than that of water, consult the procedure for Measurement
of Concentration on the next page to achieve your desired water-to-product ratio. For water-thin products, use the chart below
as a guideline. Because such factors as inlet water pressure and temperature can affect dilution ratios, the figures listed below
are only approximate. Test the actual dilution you are achieving using the Measurement of Concentration procedure for best
results. Two undrilled, clear tips are supplied for drilling sizes not listed.

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 water/product mixture,
and the amount of concentrate used in preparation of the solution dispensed. The water-to-product ratio is then calculated
as follows:
HydroMinder Model 511 Parts Diagram/List
a
b
Dilution (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.
e
Operation:
Open the water supply ball valve. When the solution in the reservoir reaches the level set by the float, the valve will close. This
will stop the water flow and siphoning of concentrate. When withdrawal of solution from the reservoir causes the level to drop
more than 1-1/2 inches, the valve will open, and the reservoir will be refilled to the previous, pre-set level. This cycle will be
repeated automatically until the supply of concentrate is depleted. The ball valve should be fully closed when changing
metering tips or concentrate container, when reservoir is drained, or when the unit is not in use.

* In hard water areas, scale may form at the discharge of the eductor. This scale may be removed by
soaking the eductor in a descaling solution or by running the descaling solution through the system. If
descaling solution is educted through the system, flush the unit by educting water only before returning
the system to regular use.
