Package Should Contain:
1. Proportioner unit.
2. Supply tubing 6.4m total.
3. Foot valve assemblies & weights (5).
4. Discharge tubing for each eductor.
5. Metering tip kits.
6. Mounting anchor kit.
7. Hose hook for 14 LPM eductor.
8. Instruction sheet.
Installation and Operation:
1. Remove cabinet cover. Drill holes for the three wall anchors with an 8mm drill bit, using the cabinet back as a template
for correct 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 1.8 metres
above the bottom of the concentrate container, nor below the highest concentrate level (never mount your
concentrate higher than the proportioner).
2. 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 not being
used. (This may be used for dispensing water only).
3. Attach the chemical suction tube assembly to the selector valve, sliding the open end of each piece of tubing over
one barb on the valve. Make sure suction tubes are on the barb far enough to prevent air from leaking into tube.
4. Slip other end of supply tube through an opening in either side of the cabinet and slide a ceramic weight over the
tube, then push a footvalve into the end of the tube. (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 4 LPM eductor; minimum tube length is 20cm for correct operation. Longer
tubes (1.2 m) are used with a 14 LPM 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
longertubes to allow discharge tube to 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 13mm ID to water inlet swivel. (Minimum 1.76 Bar pressure, with water running,
is required for correct 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 wishto 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 pushed fully in and so lock in the "on" position. To unlock, PULL THE BUTTON OUT.
