Control elements of the ScrubberGuard on the cabinet
The ScrubberGuard is controlled via four control elements located on the cabinet. These are
three buttons plus a control input for external actuation. Only one control element may be
active at any one time. Activation is confirmed by the respective button lighting up. If mul-
tiple functions are activated, this leads to a fault that is signaled by the flashing buttons. To
rectify this problem, all functions must be deactivated.
▪
In order to ensure correct operation, the AquaScat SG (A) must be connected and the
communication between the AquaScat SG (A) and cabinet must be established.
▪
If the optional inlet pump is installed, the supply line must be filled with water before-
hand.
