Zebra Technologies MIX05120 Measurement of Concentration, Troubleshooting, Parts Information

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

1.Unit does not draw concentrate

2.Water gets into concentrate container

3.Unit continuously draws concentrate

Cause

a. Clogged foot valve strainer b. Metering tip orifice obstructed c. Water pressure too low

d. Mineral deposits in eductor e. Flooding ring not in place

f.Breather hole unopened

g.Concentrate too viscous

a. Heavy mineral deposits in eductor b. Faulty or missing foot valve

a. End of discharge tube lower than eductor

Remedy

a. Clean or replace

b. Rinse orifice or replace with new tip

c. Minimum 25 PSI required. Replumb line or use different source

d. Descale* or replace eductor e. Replace discharge tube

f.Open breather hole in concentrate container

g.Max. viscosity 500 SUS

a. Descale* or replace eductor b. Repair or replace foot valve

a. Always hang discharge tube from unit 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.
