Troubleshooting Chart:

* 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.
