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 ½" 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.
