TROUBLESHOOTING CHART:
Problem
Cause
1. No discharge
a. No water
b. Magnetic valve not functioning
c. Excessive water pressure
d. Eductor clogged
e. Low flow mechanism failure
f. High flow mechanism out of
adjustment
g. High flow mechanism broken
h. Clogged water inlet strainer
2. No concentrate draw
a. Clogged foot strainer
b. Metering tip or eductor has scale
build-up
c. Low water pressure
d. Discharge tube and/or flooding
ring not in place (high flow only)
e. Concentrate container empty
f. Clogged water inlet strainer
g. Selector out of position
h. Check valve installed backwards
i. Air leak in chemical pick-up tube
j. Clear plastic tip installed in inlet
hose barb
3. Excess concentrate draw a. Metering tip not in place
4. Failure of unit to turn off
a. Water valve parts dirty or defective a. Clean* or replace with valve parts kit
b. Magnet doesn't fully return
c. Excessive water pressure
d. Mechanism hangs up
5. Excess foaming in
a. Air leak in chemical pick-up tube
discharge
* 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.

Solution
a. Open water supply
b. Install valve parts kit
c. Install regulator if flowing water pressure
exceeds 60 PSI
d. Clean* or replace
e. Install new parts
f. Adjust cable tension by loosening lock nut and
increasing tension on cable. Retighten lock
nut.
g. Cable extremely loose/broken. Order
replacement gun/cable assembly.
h. Disconnect inlet water line and clean strainer.
a. Clean or replace
b. Clean (descale)* or replace
c. Minimum 25 PSI (with water running)
required to operate unit properly
d. Push tube firmly onto eductor discharge
hose barb, or replace tube if it doesn't have
a flooding ring
e. Replace with full container
f. Disconnect inlet water line and clean strainer
g. Assure selector is in position desired
h. Confirm colored side is pointed toward eductor
i. Put clamp on tube or replace tube if brittle
j. Replace with colored metering tip
a. Press correct tip firmly into barb on select valve
b. Make sure magnet moves freely.
Replace spring if short or weak
c. Install regulator if pressure (with water
flowing) exceeds 60 PSI
d. Be sure bracket is free to move and not broken
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 ********************************************
protective clothing and eyewear when dispensing chemicals or other materials.
WEAR
observe safety and handling instructions of the chemical manufacturers.
ALWAYS
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.
re-assemble equipment according to instruction procedures. Be sure all components
ALWAYS
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
NOTE
must be mounted so that the bottom of the cabinet is above the overflow rim of the sink.
Ins
tallation and Operation:
1. Find suitable place close to water source for unit. Mounting bracket should be installed approx. 5' from floor. Level bracket
& mark holes. Drill 9/32" holes & install mounting anchors and screws in bracket.
2. Hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet & drill 9/32" hole. Install anchor and
screw to lower unit hole. When mounting unit do not mount any higher than 5 feet from the floor. Also, never mount
your concentrate container higher than the unit.
3. Select 4 metering tips for the selector valve attached to the low flow (gray) eductor, and 2 tips for the select valve attached
to the high flow (yellow) eductor. Push each tip firmly into a separate hose barb extending from the selector valve.
NOTE: The two hose barbs on the select valve attached to the high flow (yellow) eductor have been blocked with clear
tips for dispensing water. These may be replaced with colored metering tips if
additional high flow products are desired. NOTE: additional pickup lines will be needed.
4. Cut tubing provided into separate supply tubes for each product to be dispensed.
Supply tubes should reach from hose barbs on the selector valve body to bottom of
concentrate containers. Slide ceramic weights over one end of each tube
and slide foot strainer into the same ends of the tubes. Remember to include check
valves in the proper places in the supply tubing, colored end facing eductor body, as
shown (see diagram Page 3). Additional tubing is provided for drain hole in bottle fill
drip tray. NOTE: When routing pickup line(s) through unit, direct pickup line
through clip(s) in cabinet back to ensure proper operation. (see diagram1)
5. Place strainer ends of supply tubes into concentrate containers. REMEMBER
TO CHECK STRAINERS PERIODICALLY FOR CLOGGING:CLEAN IF NECESSARY.
6. Replace unit cover. Be sure cover is labeled to allow identification of products to be dispensed.
7. Connect water supply hose to water inlet swivel. (Minimum 25 PSI pressure, with water running, is required for proper
operation.) Turn on water supply.
8. Purge air from system by repeated rapid depressions of activating devices. The 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. The bucket
fill activates by holding and depressing lever of gun. To stop flow, release lever. The lever can be locked on by flipping
clip to hold lever. CAUTION: Lever must be manually unlocked to stop flow. Overflow will result if left locked
in open position.
Package Should Contain:
1. Proportioner unit with discharge tubes.
2. (2) lengths of chemical inlet tubing,
1/4" x 21' & 1/4" x 14'.
3. Mounting Bracket.
4. Dispensing Gun.
5. Accessory kit containing:
(2) "Y" hose barbs,(6) in-line check
valves, (4) weights, (4) foot strainers,
(2) metering tip kits, (3) mounting
screws and (3) anchors.
6. Instruction sheet.
