Troubleshooting Chart:

Problem

Cause

1. No discharge

a . No water

b. Magnetic valve not functioning

c. Excessive water pressure

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 flooding

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

i. Selector out of position

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, firmly 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 flush the unit by

drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.

e . Replace with full container

f. Tighten, but do not overtighten

g. Disconnect inlet water line and clean

strainer

h. Put clamp on tube or replace tube if brittle

i. Assure selector is in position desired

a . Press correct tip firmly into barb on

eductor

b. Place concentrate below the eductor

a . Clean* or replace with valve parts kit

b. Make sure magnet moves freely.

c. Remove button and clean cabinet/button

to remove any dirt lodged in slide recess

a . Put clamp on tube or replace tube if brittle

THANK YOU FOR YOUR INTEREST IN OUR PRODUCTS

Hydro Systems manufactures quality chemical proportioning equiment. Please use this equipment

carefully and observe all warnings and cautions.

********************************************************* NOTE *********************************************

WEAR

protective clothing and eyewear when dispensing chemicals or other materials.

observe safety and handling instructions of the chemical manufacturers.

ALWAYS

direct discharge away from you or other persons or into approved containers.

ALWAYS

dispense cleaners and chemicals in accordance with manufacturer's instructions. Exercise

CAUTION when maintaining your equipment.

equipment clean to maintain proper operation.

KEEP

WEAR

protective clothing and eyewear when working in the vicinity of all chemicals, filling or

emptying equipment or changing metering tips.

ALWAYS

re-assemble equipment according to instruction procedures. Be sure all components are

firmly screwed or latched into position.

ATTACH

only to tap water outlets (85 PSI maximum).

If the unit is used to fill a sink or the discharge hose can be placed into a sink, the unit must

NOTE

be mounted so that the bottom of the cabinet is above the overflow rim of the sink.

Installation and Operation:

1 . Remove cabinet cover.

Drill holes for the three wall anchors with a 5/16" drill bit, using the cabinet back as a template

for proper 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 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 . 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.

3 . 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.

4 . 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.)

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 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.

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 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.

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 wish to 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 fully depressed and allows it to

latch in the "on" position. To unlock, pull the button out.
