Unscrew the locking mechanism for the flap housing.
Pull the pump connection and backflow preventer off.
Submerse the backflow preventer and pump connection
in a water bath. If necessary, the components should be
cleaned.
If necessary, clean the (optional) alarm probe; use the
same procedure as for the backflow preventer.
Use a wet vacuum cleaner to empty the pump sump and
then clean the (inside) of the tank with a damp cloth.
Assemble the components again in reverse order.
Connect to the power supply again. Check if the system is
running.
