Through proper care and maintenance, this equipment will serve your toughest cleaning jobs.
Installation:
1. Select a metering tip (see next three sections) and insert it into the suction stub on the eductor body.
2. Attach the end of the discharge tube with the clamp and flooding ring to the discharge barb on the eductor. Since the
HydroMinder 506 does not have a siphon breaker, you may want to drill a small hole (1/8" or 1/4" ID) in the discharge
tube, above the highest solution level and below the discharge end of the eductor. This will allow the discharge tube
to drain after each cycle.
3. Mount the unit in a level position on the side of the reservoir. The U-clamp may be repositioned or removed as necessary.
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. Slide the open end of the suction tube over the suction stub.
6. 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.
7. Install a minimum 1/2-inch ID water hose between the inlet threads and the water spigot. Minimum water pressure required to properly operate the proportioner is 25 PSI (flowing).
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:
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.

* 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.

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.
