metering tip selection
Metering Tip Selection:
The final concentration of the dispensed solution is related to both the size of the metering tip opening and the viscosity of the liquid being
siphoned. For water-thin products, the chart can be used as a guideline. If product is noticeably thicker than water, consult the Measurement
of Concentration procedure to achieve your desired water-to-product ratio. Because dilution can vary with water temperature and pressure,
actual dilution achieved can only be ascertained by using the Measurement of Concentration procedure. The clear, undrilled tip is provided
to permit drilling to size not listed should you need a dilution ratio that falls between standard tip sizes.
NOTE: A 1 GPM eductor is gray; a 3.5 GPM eductor is yellow. Refer to parts diagram if unfamiliar with names of system components.
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 solution, and the amount of concentrate used in
preparation of the solution dispensed. The water-to-product ratio is then calculated as follows:
Dilution Ratio (X:1) where 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.

troubleshooting
Problem Cause Solution
1. No discharge a. No water a. Open water supply
b. Excessive water pressure b. Install regulator if water pressure (with
water running) exceeds 85 psi.
c. Clogged water inlet strainer c. Disconnect inlet water line and clean
strainer
d. Magnetic valve not functioning d. Install valve parts kit
e. Eductor clogged e. Clean* or replace
2. No concentrate draw a. Clogged foot valve a. Clean or replace
b. Metering tip or eductor has scale
build-up
b. Clean (descale*) or replace
c. Low water pressure c. Minimum 25 psi (with water running)
required to operate unit properly
d. For E-Gap version, discharge tube not
in place
d. Push tube firmly onto eductor discharge
hose barb.
e. Concentrate container is empty e. Replace with full container
f. Clogged water inlet strainer f. Disconnect inlet water line and clean
strainer
g. Inlet hose barb not screwed into
eductor tightly
g. Tighten, but do not overtighten
h. Air leak in pick-up tube h. Put clamp on tube or replace tube if brittle
i. For AirGap version, no flooding feature
in the eductor
i. Replace eductor if all other items in
problem 2 are ok
3. Excess concentrate draw a.
b.
Metering tip not in place
Chemical above eductor
a.
b.
Press correct tip firmly into barb on
eductor
Place concentrate below eductor
4. Failure of unit to turn off a. Water valve parts dirty or defective a. Clean or replace with valve parts kit
b. Magnet doesn‘t fully return b. Make sure magnet moves freely
replace spring if short or weak
c. Push button stuck c. Remove button and clean cabinet/button
to remove excess dirt lodged in slide
recess
5. Excess foaming in discharge a. Air leak in pick-up tube a. Put clamp on tube or replace tube if brittle
b. For 1 GPM AirGap version, excessive
air mixed with chemical
b. Put foam reduction tube on eductor
nozzle
6. Water Discharge from AirGap
Backflow Device
a. Restricted discharge hose a. Be sure discharge hose is not immersed,
kinked or elevated. Be sure there is no
liquid in the disharge hose when begining
to operate dispenser.
b. High water pressure b. Install pressure regulator if flowing water
pressure exceeds 85 psi.
* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are
exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove
an eductor located in the cabinet, firmly grasp water valve and unscrew the eductor. Replace in same manner. Alternatively, a
scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with
the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing
clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.
