Troubleshooting Chart:
Problem
Cause
Solution
1. No discharge
a. No water
b. No power
a. Open water supply
b. Make sure solenoid is receiving signal
from power source
c. Shut off inlet water and clean strainer
c. Clogged water inlet strainer
2. No concentrate draw
a. Clogged foot valve
b. Eductor clogged
c. Low water pressure
i. Air leak in chemical supply tube
a. Clean or replace
b. Clean (de-scale)* or replace
c. Minimum 40 PSI (dynamic) required
for system to operate properly with 20 PSI
back pressure
d. Reduce back pressure by moving
discharge location or reducing flow near
injection point
e. There must be some back pressure for
eductor to develop vacuum. A length of
discharge tubing should be sufficient.
f. Replace chemical source
g. Tighten to prevent air leaks, but do not
overtighten
h. Disconnect inlet water line and clean
strainer
i. Put clamp on tube or replace tube if brittle
a. Water valve parts clogged
b. Control source not shutting off
a. Clean* or replace with valve parts kit
b. Ensure that control source is properly set
d. Excess back pressure
e. Insufficient back pressure.
f. Chemical source empty
g. Inlet check valve not screwed
into eductor tightly
h. Clogged water inlet strainer
3. Failure of unit to turn off
* 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.

Installation and Operation:
1. Find a suitable place to locate system, refer to FIG.1 for detailed information.
2. Remove front cover to gain access to mounting holes.
3. Mark mounting holes. Drill 9/32" holes and install mounting anchors and screws. Slide key holes
in cabinet back over screw heads, tighten screws, then install bottom screws.
4. Cut supply tubing provided into separate supply tubes for each product to be used. For solid dissolving
system applications the supply tube should connect from the hose barb on the eductor check valve to the
discharge port on the reservoir. For liquid drum applications cut supply tube to be able to reach the bottom
of the liquid drum. Slide the ceramic weight over the tube and install a footvalve into the same end of the
tube. Connect open end of supply tube to the hose barb of the eductor check valve.
Remember to check foot valve strainers periodically for clogging: Clean if necessary.
5. Connect inlet water supply using provided 1/2"OD tubing. Tubing should go from fresh tap water source
to the inlet connection on the eductor system. Incoming pressure must be consistent and at least 40 psi.
6. Install the provided injection check valve into the injection port. Use thread sealant to ensure a leak-free
seal. Note that this fitting is not needed for installations that go directly to the tower or makeup tank.
7. Connect discharge tubing using provided 1/2"OD tubing. Tubing should go from discharge connection
on the eductor system to the injection check valve or direct to the tower or makeup tank as needed.
8. Connect provided AC adapter from solenoid coil (polarity does not matter) to controller source (timer or
controller). Make sure that wires do not rest on solenoid coils.
9. Replace cabinet cover.

10. Turn on inlet water supply. Manually activate each of the eductors using the control source. As each
of the eductors is activated, it will draw chemical through the supply tube and into the discharge tube. An
optional calibration column can be used to accurately measure chemical delivery rates. Eductor must have
some back pressure to develop vacuum, even a short length of discharge tubing should be sufficient.
