Recovery System 67Service Manual – SC500
Recovery System
Functional Description
The recovery system removes the dirty water from
the oor and pipes it to a recovery tank. When the
machine is running, the dirty water on the oor is col-
lected by the squeegee blades and collected through
the slots in the same, piped through the vacuum hose
and into the tank by the airow created by vacuum
motor (M2). The dirty water is piped into the recovery
tank, while the airow continues to the vacuum fan.
A tank with a grid collects the largest debris going
through the recovery tank hose.
The automatic oat in the vacuum grid stops vacuum
system motor (M2) from collecting any liquids.
When the automatic oat closes and shuts down the
vacuum system, the vacuum system motor noise will
increase and the oor will not be dried.
The vacuum system is activated automatically with the
One-Touch button . It can then be managed inde-
pendently via the vacuum button . The vacuum
system is activated in full power or silent mode depend-
ing on the last mode in use before the machine was
switched off. This mode can be changed by repeatedly
pressing the vacuum button . The various vacuum
modes are also displayed on the multifunction display.
When the recovery tank is full it can be emptied
through the drain hose.
