C5 Front Loading Dishwasher With Incorporated Continuous Water Softener - Electrolux LU7 Owner's Manual

C5 FRONT LOADING DISHWASHER WITH
INCORPORATED CONTINUOUS WATER
SOFTENER
These models have a continuous softener in the dish-
washer water circuit. By means of special resins, this
device removes the calcareous substances from the
feed water, supplying decalcified water for washing.
For the continuous softener to work properly the resins
must be regenerated periodically, with frequency
depending on the hardness of the water and the num-
ber of wash cycles carried out.
Unlike conventional water softeners, this continuous
softener does not require machine stops for regenerat-
ing the resins.

only salt may be placed in the salt con-

cal substances such as detergent, rinse

inevitably damage the appliance. Such
damage invalidates any warranty and
relieves the manufacturer of all liability.

container thread and the closing cap seal.
• Refit the cap of container "A", turning it clockwise
