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
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.
Troubleshooting:
Problem Cause Remedy
1. Unit does not draw a. Clogged foot valve strainer a. Clean or replace
concentrate b. Metering tip orifice obstructed b. Rinse orifice or replace with new tip
c. Water pressure too low c. Minimum 25 PSI required. Replumb line
or use different source
d. Mineral deposits in eductor d. Descale* or replace eductor
e. Flooding ring not in place e. Replace discharge tube
f. Breather hole unopened f. Open breather hole in concentrate container
g. Concentrate too viscous g. Max. viscosity 500 SUS
2. Water gets into a. Heavy mineral deposits in eductor a. Descale* or replace eductor
concentrate container b. Faulty or missing foot valve b. Repair or replace foot valve
3. Unit continuously draws a. End of discharge tube lower than a. Always hang discharge tube from unit
concentrate eductor using hook provided on end
* Mineral deposits, known as scale, may form at the discharge of the eductor, particularly in hard water areas. To
remove scale, soak the eductor in a descaling or deliming solution. Alternately, the descaling solution can be
siphoned into the eductor by operating the unit with the foot valve in the descaling solution. After operating the
unit in this manner for a minute, put foot valve in clear water and operate for another minute to flush the unit.
Return the foot valve to the concentrate for normal use.
