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.
