Install the sensor cable, flush hose and recirculation hose
Remove the protective film and lift up the drain grate and Funnel. Set them aside.
Route the sensor cable through the drain pipe, to where 20 cm of slack is visible in the drain unit. Keep the connector protection cover on.
Notice
It is recommended to use fish tape to route the cables through the pipes.
Route the flush hose and recirculation hose through the drain pipe, with the couplings down towards the drain unit.
