Troubleshooting Chart:
* 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.

Package Should Contain:
1. Find suitable place close to water source for unit. Remove dispenser cover by first pulling to remove the knob from the QDV
valve, then 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 mount-
ing 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 (up to 4) for the QDV valve. (see next two sections) Push each tip firmly into a separate hose barb ex-
tending 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. Install four 5.5" precut lengths of tubing onto the four hose barb ports of the QDV valve. Insert four in-line check valves,
with arrows pointing toward the QDV valve, into the open ends of the pre-cut lengths of tubing.
7. Cut supply tubing provided into separate supply tubes for each product to be dispensed. Supply tubes should reach from
in-line check valve barb to bottom of concentrate container. Push one end of supply tube over the hose barb of the in-line
check valve. Slide weight over end of each tube, then install foot strainers on ends of supply tubes before placing into
concentrate containers.
REMEMBER TO CHECK FOOT STRAINERS PERIODICALLY FOR CLOGGING: CLEAN IF NECES-
SARY
8. Connect water supply hose of at least 3/8"ID to water inlet swivel. (Minimum 25 PSI pressure, with water running, is re-
quired for proper operation.) Connect opposite end of hose to water supply. Turn water supply on. Replace dispenser cover.
Hook two bottom latches, and swing up to snap over button on the top of dispenser. Reinstall knob for QDV by pushing
knob firmly onto stem.
9. 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 flooding rings from inside the tubes. Slide end of
tube with flooding 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.
10. To operate button fill units, depress button to dispense product, release button to stop flow.
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.
11. Bottle fill activates by inserting a spray bottle over the discharge tube and lifting lever until flow starts. To stop flow, lower
bottle off discharge tube. To operate units with remote bucket fill hold and depress lever of gun. To stop flow 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.
