Excess Concentrate Draw: Cause: Metering tip not in place
Solution: Press correct tip firmly into barb on eductor

Cause: Chemical above eductor
Solution: Place concentrate below the eductor
No Concentrate Draw: Cause: Clogged foot valve
Solution: Clean or replace

Cause: Metering tip or eductor has scale build-up
Solution: Clean (descale)* or replace

Cause: Low water pressure
Solution: Minimum 20 PSI (with water running) required to operate unit properly

Cause: Discharge tube(s) not in place or flooding ring missing from inner discharge tube
Solution: Push tube firmly onto eductor discharge hose barb; be sure inner discharge tube is installed and has flooding ring

Cause: Concentrate container empty
Solution: Replace with full container

Cause: Inlet hose barb not screwed into eductor tightly
Solution: Tighten, but do not overtighten

Cause: Clogged water inlet strainer
Solution: Disconnect inlet water line and clean strainer

* 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.
