Measurement of Concentration:
You can determine the dispensed water-to-product ratio for any metering tip size and viscosity. All that is
required is to operate the primed dispenser for a minute or so and not two things: the amount to 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.

(low water flow)
a. Clean or replace
b. Rinse tip or replace: Do not attempt to clean: may alter size of orifice
c. Minimum 25 PSI required
d. Back flush unit. Remove container, suction tube and metering tip. Put finger
over barrel opening. Apply minimal water pressure through garden hose
nozzle of barrel to be flushed.
e. Descale foamer by soaking in weak descaling solution
f. Clean or replace strainer.
2. Weak
foaming
action
a. Clogged water inlet strainer
b. Water pressure too low
c. Water temperature too high
a. Clean or replace
b. Minimum 25 PSI required
c. Use lower temp water source. (Concentrate flow decreases above 140˚F
water)
If above steps fail to produce good concentrate draw and/or foaming action, replace lid assembly. See component chart below.
