WATER SOFTENING

The water softener operates as follows:

During rinse, pre-wash and main wash:

1. Inlet valve 1 opens and admits water.

2. The water flows

• through hose 3 to air-brek device, no 1

• passes an airgap

• leaves the air-break device through no. 3

• passes hose 7 to the resin container of the

softener, no 3.

There the water is softened and the soft water

flows

• out through no. 4

• through hose 8 back to the air-break device no. 4

• enters the machine through no. 6.

Regeneration during the main wash:

3. When the machine has admitted water, as described above, for the main wash,

inlet valve 2 opens for 10-60 seconds, depending on the setting. The water flows

through hose 4 to the air-break device 5, on through hose 9 and into salt container no. 5.

The salt-saturated water flows into the resin container, where it regenerates the resin, so

that it can soften further water.
