 3798 Round Bottom Road, Cincinnati, OH 45244  Phone: (513) 271-8800  Fax: (513) 271-0160

Installation and Operation:

1.  Find suitable  place close to water source for unit. Mounting bracket should be installed approx. 5' from the floor. Level
 

bracket and mark holes. Drill 9/32" holes and install mounting anchors and screws in bracket.

2.   Remove cabinet cover and hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet and drill 9/32" hole.
 

Install anchor and screw in lower cabinet hole. When mounting unit, do not mount more than 5 feet from the floor. Also, never

 

mount your concentrate container higher than the unit. Keyhole slots are also provided in the cabinet back if the mounting  

 

bracket won't be used.

3.  Select metering tips (up to 4) for the selector valve. (see next two sections) Push each tip firmly 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). Select and install a metering tip for the single product eductor (right side) in the same

 manner.
4.  Cut tubing provided into separate supply tubes for each product to be dispensed (tubing allows 7 feet of tube per product).
 

Supply tubes should reach from hose barbs on the selector valve body and eductor to bottom of concentrate containers

 

Slide ceramic weights over one end of each tube and slide foot valves into the same ends of the tubes.

5.  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.)

6.  Place foot valve ends of supply tubes into concentrate containers. 

REMEMBER TO CHECK FOOT VALVE STRAINERS

 

REGULARLY FOR CLOGGING: CLEAN IF NECESSARY.

7.  A short  discharge tube is used with the 1GPM eductor; minimum tube length is 8 inches (20cm) for proper operation. Longer
 

tubes (4 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 eductors.) Hooks may be installed on longer tubes to allow

 

discharge tube to conveniently hang from dispenser when not in use.

8.  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.

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. Purge air from the system by depressing the buttons briefly. There may be some water discharge from the eductor vents
 

until the air is purged.

11. 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: 

Depress button and slide button lock up. 

To unlock, depress button and release.

12. 

It is essential that the discharge hose not be obstructed. If discharge is  restricted, water will flow out the  eductor

 

vents. Do not start to operate the dispenser with liquid in the discharge tube.

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.
