Measurement of Concentration:
Youcan determine the dispensed water-to-product ratio for any metering tipsize and product viscosity. All that is required
istooperatethe primed dispenser for a minute or so and note two things: the amount of dispensed water/product mixture,
andtheamountof concentrate used in preparation ofthesolutiondispensed.Thewater-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.
Alternativemethods tothistestare 1)pH(using litmuspaper),and 2)titration.Contact yourconcentratesupplier forfurther
information on these alternative methods and the materials required to perform them.
Operation:
Open the water supply ball valve. When the solution in the reservoir reaches the level set by the float, the valve will close.
Thiswillstopthewaterflowandsiphoningofconcentrate.When withdrawal of solution from the reservoir causes the level
todropmore than1-1/2inches,the valve willopen,and the reservoirwillberefilled totheprevious,pre-set level.Thiscycle
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.
Troubleshooting:
Problem Probable Cause Remedy
1. No discharge a. No water a. Open water inlet
b. Defective magnetic b. Replace assembly
valve assembly
c. Excessive water pressure c. Install regulator if pressure exceeds 85 PSI
2. No concentrate a. Clogged foot valve a. Clean or replace foot valve
draw b. Metering tip or eductor b. Clean* or replace
clogged
c. Low water pressure c. Minimum 25 PSI flowing required
d. Discharge tube or d. Check position: Replace discharge tube if
flooding ring not in place flooding ring is missing.
3. Failure of unit to a. Valve parts dirty or a. Clean or replace
turn off defective
b. Magnet spring too short b. Replace
c. Clogged valve orifice c. Clean or replace
4. Backflow into a. Diluted solution being a. Replace or repair foot valve
concentrate siphoned into container
b. Water being siphoned b. Replace eductor
into container
*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.
