Litering out the filter

 Switch off the system.

 Drain half the recycled water tank

through the drain valve (up to the con-

nection of the recirculation valve).

 Close the drain valve.

 Measure the distance between the wa-

ter surface and the rim of the cover in

the recycled water tank (use a metre-

stick and a flashlight).

 Switch on the system and let it run for exact-

ly 5 minutes. Switchoff the system.

 Measure the water level again.

Filament filter

Check filtering capacity. As long as the washing unit draws waterwater, the wa-

ter level in the recycled water tank must not fall below the starting level S9.

Trigger the manual backwash or clean or change filter module if capacity is

too low.

72 = filling capacity in litres per hour

With 2 tanks: (height difference in cm) x

 Add 500 l/h to the determined filling capaci-

ty (loss by recirculation during filling).
