The recovery tank (Fig. 25/4)
must be emptied and flushed
clean after finishing work.
Observe the applicable laws
and local regulations when dis-
posing of waste water contain-
ing cleaning agents!

3. Detach the waste water draining
hose (Fig. 25/6) and lower it slowly.
4. Unscrew the cap (Fig. 25/5) to open
it. The quantity drained can be regu-
lated by turning the cap and pivoting
the cap open fully, if necessary.

completely emptied, screw the cap
shut again and attach the draining
hose again.
If the recovery tank is extreme-
ly dirty, begin cleaning the tank
straight away.

washer or with a steam blaster
because the temperature is in
excess of 100 °C.
Wear appropriate gloves for
protection against dirt, viruses,
bacteria etc. when cleaning the
container.
