Troubleshooting Chart:
Problem
Cause
1. No discharge a. No water
b. Magnetic valve not functioning
d. Eductor clogged
e. Clogged water inlet strainer
2. No concentrate draw a. Clogged foot valve
b. Metering tip or eductor has
scale build-up
c. Low water pressure
d. Discharge tube and/or fl ooding
ring not in place
e. Concentrate container empty
f. Inlet hose barb not screwed
into eductor tightly
g. Clogged water inlet strainer
h. Air leak in chemical pick-up tube
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
* 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, fi rmly 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
fl ush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into
concentrate.

equipment clean to maintain proper operation.
KEEP
if the unit is used to fi ll a sink or discharge hose can be placed into a sink, the unit must be mounted so that the bottom of the
NOTE
cabinet is above the overfl ow rim of the sink.
Installation and Operation:
1. Find suitable place close to water source for unit. Remove dispenser cover by depressing the button on the top of the dispenser
and pull the cover forward and off. Do not mount dispenser 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. Remove mounting rail from the back of dispenser by rotating the black lock bars, located on the inside back of dispenser, rotate
toward the outside of the dispenser.
3. Hold mounting rail level against wall and mark (2) mounting holes. Drill 9/32" hole and install anchors in wall. Secure mounting
rail to wall with screws provided. NOTE: Distance from top of mounting rail to top of dispenser is 2.5". If mounting dispenser
under cabinet or shelf be sure to leave clearance to access button at the top of dispenser for removal of cover.
4. Place the dispenser over the mounting rail aligning the bosses around the mounting screws with the large holes in the dispenser
back. Rotate the locking tabs toward the center of the dispenser to secure the dispenser to the wall. NOTE: IT IS REQUIRED
THAT A SAFETY SCREW BE INSTALLED. Mark the wall using one of the lower holes in the back of the dispenser. Remove
the dispenser from the mounting rail by rotating locking tabs toward the outside of the dispenser then lifting the dispenser off of
the mounting rail. Drill 9/32" hole and install anchor. Reattach the dispenser to the mounting rail (see #4). Install security screw
through the back of the dispenser into anchor in the wall.
5. Select metering tips for the selector valve(s) or hosebarb. (see next two sections) Push each tip fi rmly into a separate hose barb
extending from the selector valve. A tip with no hole (clear plastic) can be used to block any valve port being used. (this may be
used for dispensing water only).
6. Cut supply tubing provided into separate supply tubes for each product to be dispensed. Supply tubes should reach from hose
barb on eductor to bottom of concentrate container. Slide ceramic weight over one end of tube and slide a footvalve into the
same end of the tube. (prepare a tube for each eductor.)
7. 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)
8. Place footvalve ends of supply tubes into concentrate containers. REMEMBER TO CHECK FOOT VALVE STRAINERS
PERIODICALLY FOR CLOGGING: CLEAN IF NECESSARY
9. 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.
10. A short discharge tube is used with the 1GPM eductor; minimum tube length is 8 inches (20cm) for proper operation. Longer
tubes (6 feet) are used with a 3.5 GPM eductor. Do not remove the fl ooding rings from inside the tubes. Slide end of tube with
fl ooding ring over eductor discharge outlet. (Repeat for all discharge outlets.) Hooks may be installed on longer tubes to allow
discharge tube to conveniently hang from dispenser when not in use.
11. Replace dispenser cover. Hook two bottom latches, and swing up to snap over button on the top of dispenser.
12. To operate button fi ll units, depress button to dispense product, release button to stop fl ow. IF YOU WISH TO BE ABLE TO
LOCK THE BUTTON IN THE "ON" POSITION: Depress button and slide button lock up, TO UNLOCK, DEPRESS BUTTON
AND RELEASE.
13. Bottle fi ll activates by inserting a spray bottle over the discharge tube and lifting lever until fl ow starts. To stop fl ow, lower bottle
off discharge tube. To operate units with remote bucket fi ll hold and depress lever of gun. To stop fl ow release lever. IF YOU
WISH TO BE ABLE TO LOCK THE REMOTE BUCKET FILL IN THE "ON" POSITION: Depress lever and position lock on
bottom of lever, TO UNLOCK, DEPRESS LEVER AND RELEASE.
