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.

c. Minimum 25 PSI required
d. Back ush unit. Remove container, suction tube and metering tip. Put nger
over barrel opening. Apply minimal water pressure through garden hose
nozzle of barrel to be ushed.
e. Descale foamer by soaking in weak descaling solution
f. Clean or replace strainer.
2. Weak

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 ow 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.

Operation:
1. Unscrew foamer lid assembly from container.
2. Select a metering tip using the chart below as a guideline and press the tip rmly into the hose barb on the bottom of the lid assembly. Install the
suction tube on the hose barb.
3. Fill the container with concentrate. Screw foamer lid assembly securely onto container.
CAUTION: Foamer lid assembly must be securely fastened to container to prevent accidental spilling of concentrate during
use of foamer.
4. Insert foamer lid assembly into female quick to connect on spray gun.
5. Connect a garden hose with 3/4” male garden hose thread to the base of the spray gun handle. Turn on the water supply to the hose. (Minumum
25 PSI water pressure is required to operate the foamer.)
6. Grasp the spray gun handle in one hand and the foamer container in the other. Squeeze the spray gun handle to begin foaming. Continuous
operation can be achieved by using the handle lock provided on the spray gun. Rinse by disconnecting the spray gun from the foaming lid
assembly. To remove the foamer from the spray gun, simply grasp the quick connect on the spray gun in one hand and the foamer assembly in the
other. Pull in opposite directions. (The outside collar around the quick connect will slide toward the spray gun, disengaging the foamer barrel.)
Metering Tip Selection:
Dilution ratios below were achieved at 40 PSI, cold water and water-thin viscosity (1.0 CP). Ratios will vary given PSI, water and ambient temperature,
water ow rate, and product viscosity. At water-thin viscosity, the efciency of the eductor is at its maximum with the black or gray tip. Removal of the
foot strainer on the concentrate pick-up tube will also change these ratios. *If no tip is listed, the dilution ratio delivered falls between those shown.
