higher than the unit. Keyhole slots are also provided in
the cabinet back if the mounting bracket won’t be used.

barb on eductor body.
4. 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.)
5. Push other end of supply tube over the hose barb/
metering tip on the eductor. (Repeat for all eductors.)

eductor. Slide end of tube over eductor discharge outlet.
(Repeat for all eductors.) Direct hoses to the appropriate
sink basin. Secure using zip ties if necessary.

slots in sides of 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.

Operation:
1. 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.
2. Purge air from the system by depressing
the buttons briey. There may be some water
discharge from the eductor vents until the air is
purged.
3. Push button to start ow of desired water/
concentrate solution, and hold until supply
tube is primed. Then push the button whenever
dispensing is desired, and release button to stop

obstructed. If discharge is restricted, water will
ow out the eductor vents. Do not start to operate
the dispenser with liquid in the discharge tube.
