Maintenance and care

7.1

Maintenance

The complete system must be visually inspected at regular intervals (every 3 months). During every in-
spection, all screw connections should be checked to ensure they are tight. The seat and function of the
float valve in the intake tank should also be checked. If the system will not be used for a long period or if
there is a risk of frost, it should be emptied. If put into temporary storage, it must be stored in a dry, well
ventilated place.
7.2

Care

To clean and care for the system it is sufficient to wipe it down with a damp cloth. If the system is very
dirty, a mild cleaning agent may also be used. Never use solvents or cleaning products that contain sol-
vents.

Troubleshooting

If a fault occurs:
Press the RESET switch
If this does not solve the problem, disconnect the plug from the mains, wait about 15 seconds and plug in
again.
What to do if...

there is an overflow on the unit (water leaking from DN 40 drain pipe)?
The float valve's lifting body is rubbing against the inside of the unit.
Centrally align float valve.
Float valve has become dirty during pipe installation.
Switch control unit to manual mains water mode. Open a consumer and allow pump to run for about
1 minute. This should flush the dirt out of the valve.

the unit is not running in mains water mode:
Mains water connection is not open.
3-way valve has not switched over (check valve position)
If the steps described above do not solve the problem, please contact customer service.
