Troubleshooting Chart:
Problem
Cause
1. No discharge
a . No water
b. Magnetic valve not functioning
c. Excessive water pressure
d. Eductor clogged
2. No concentrate draw
a . Clogged foot valve
b. Metering tip or eductor has
scale build-up
c. Low water pressure
d. Discharge tube not in place
e . Concentrate container empty
f. Inlet hose barb not screwed
into eductor tightly
g. Clogged water inlet strainer
3. Excess concentrate draw
a . Metering tip not in place
b. Chemical above eductor
4. Failure of unit to turn off
a . Water valve parts dirty or
defective
b. Magnet doesn't fully return
c. Push button stuck
5. Excess foaming in discharge
a . Air leak in pick-up tube
6. Water discharge from air
a . Restricted discharge hose
vents on eductor
b. High water pressure
* 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 unthread 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.

c. Remove button and clean cabinet/button
to remove any dirt lodged in slide recess
a . Put clamp on tube or replace tube if brittle
a . Be sure discharge tube is not immersed,
kinked or elevated. Be sure there is no
liquid in the discharge tube when begin-
ning to operate dispenser
b. Install pressure regulator if flowing water
pressure exceeds 60 PSI (flowing)

Please use this equipment carefully and observe all warnings and cautions.
****************************************************** NOTE ****************************************************
WEAR
protective clothing and eyewear when dispensing chemicals or other materials.
ALWAYS
observe safety and handling instructions of the chemical manufacturers.
direct discharge away from you or other persons or into approved containers.
ALWAYS
dispense cleaners and chemicals in accordance with manufacturer's
ALWAYS
instructions.
KEEP
equipment clean to maintain proper operation.
protective clothing and eyewear when working in the vicinity of all
WEAR
chemicals, filling or emptying equipment or changing metering tips.
ALWAYS
re-assemble equipment according to instruction procedures. Be sure all
components are firmly screwed or latched into position.
ATTACH
only to tap water outlets (85 PSI maximum).
Installation and Operation:
1. Remove cabinet cover.
Drill holes for the three wall anchors with a 5/16" drill bit, using the cabinet back as a template for
proper spacing of the mounting screws. Install mounting anchors, and then screws in top two anchors. Slide key holes in
cabinet back over screw heads, tighten screws, then install bottom screw. Do not mount more than 6 feet (1.8 meters) above
the bottom of the concentrate container, nor below the highest concentrate level (never mount your concentrate higher than
the proportioner).
2. Select a metering tip (see next section), and insert into hose barb on eductor body. (Repeat for all eductors.)
3. Supply tube should reach from hose barb on eductor to bottom of the concentrate container. Cut supply tube provided to
length required. Slide a ceramic weight over one end of tube and slide a foot valve into the same end of the tube. (Prepare
a tube for each eductor.)
4. Slip other end of supply tube through an opening in either side of the cabinet and push over the hose barb/metering tip on
the eductor. (Repeat for all eductors.)
5. Place foot valve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINERS
PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY.
6. A short discharge tube is used with the 1GPM eductor; minumum tube length is 8 inches (20cm) for proper operation.
Longer tubes (4 feet) are used with a 4 GPM eductor. Do not remove the flooding rings from inside the tubes. Slide end
of tube with flooding ring over eductor discharge outlet. (Repeat for all eductors.) Hooks may be installed on longer tubes
to allow discharge tube to conveniently hang from dispenser when not in use.
7. Replace cabinet cover. Push the sides in, behind the latch holes, to snap the cover in place. The two screws provided may
be installed in the holes in the cabinet sides to prevent easy removal of cover.
8. Connect water supply hose of at least 3/8" ID to water inlet swivel. (Minimum 25 PSI pressure, with water running, is required
for proper operation.) Connect opposite end of hose to water supply. Turn water supply on.
9. Push button to start flow of desired water/concentrate solution, and hold until supply tube is primed (filled). Then push the
button whenever dispensing is desired, and release button to stop flow of solution. If you wish to be able to lock the button
in the "on" position: clip or bend the two tabs behind the lower front portion of the button (see diagram). This allows the
button to be fully depressed and allows it to latch in the "on" position. To unlock, pull
the button out.
