Setting the immersion depth and
installing the bracket
 Insert the interior cleaner onto the ob-
ject to be cleaned using the container
hole cone on the support tube.
 Loosen the screw connection at the
container hole cone.
 Adjusting the immersion depth: Insert
the interior cleaner into the opening in
the container until the suction tube
touches the floor. Now lift up the interior
cleaner far enough (2-3 mm), until the
suction tube no longer touches the
floor.
 Tighten the screw connection at the
container hole cone.
 Install the bracket on the support tube
to ensure a more stable position of the
interior cleaner.
Connecting the hoses
 Connect the high pressure pump to the
interior cleaner via a high pressure
hose.
 Connect the water output stub to a re-
spective drain hose.
Note
The drain hose must have an inner diame-
ter of at least 17 mm. In order to prevent a
possible pressure reduction in the hose as
much as possible, narrowing in the hose or
sudden changes in direction must be
avoided.
Cleaning
 Connect the interior cleaner to the pow-
er supply and to an extension cable if
necessary.
 Plug in the mains plug.
 Set the switch lever to the SPRAY posi-
tion. A cleaning will be performed at the
same time the excess water is suc-
tioned from the inside of the container.
 Switch the interior on at the appliance
switch. The indicator lamp glows green.
 Open the cleaning liquid supply.
 Switch on the separate high pressure
pump.
Note
In order to ensure a thorough cleaning of
the container, we recommend performing
two cleaning cycles. The cycle lasts 36
seconds each.
 Set the switch lever to the SUCTION
position after the cleaning has been
concluded to suction off the remaining
water from the container.

Shutting down

Note
Flush/rinse the interior cleaner for 30 sec-
onds prior to shutting it off. This will avoid
crusting and adhesion and thus a prema-
ture wear of the seals.
 Switch off the separate high pressure
pump.
 Shut off the cleaning liquid supply.
 Switch the interior off at the appliance
switch. Indicator lamp goes off.
 Pull out the mains plug.
 Remove the interior cleaner from the
container.
