Troubleshooting Chart:

Problem
1. No discharge
2. No concentrate
draw
3. Excess
concentrate draw
4. Failure of unit
to turn off
5. Excess foaming
in 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 the 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 the solution is drawn consistently, then flush the unit by drawing clear water through
it for a minute. Replace concentrate container and put the suction tube into concentrate.
