Note:
The overflow seal
0
does not fit in all overflows.
If the overflow seal
0
cannot close the overflow,
use a cloth or something similar to seal it.
Warning in regard to property
damage!
Use this appliance only on drains and pipeworks
able to withstand pressure. Support poorly seated
pipes against the floor! If you do not, the pressure
surge could damage the pipe.
4. Close the plughole with a stopper and and pour
some warm water into the bowl (up to about 7 cm
above the plughole). The best possible pressure
effect is achieved only when the blocked pipe is
completely filled with water. Without water in the
pipe the pressure effect is strongly reduced.
5. Build up a little pressure, in that you activate the
pump
3
quickly about 3 - 4 times. If you pump
too slowly, the air could escape from the
appliance.
6. Remove the stopper and place the appliance,
as shown in Fig. 6, on the plughole .
Fig. 6
7. Then release the pressure surge. When doing
this, press the appliance firmly against the plug-
hole.
8. If the blockage is not released, and you are sure
that the pipe can withstand the pressure, increase
the pressure for the next pressure surge.
9. Take the appliance out of the water and activate
the pump
3
rapidly about 10 times.
10. Should you wish to release some pressure from
the appliance, unscrew the air release valve
1
.
Afterwards, screw it back down firmly.
11. Place the appliance back onto the plughole
and activate the pressure surge.
Important:
Repeat these pressure surges only for as long as the
water level is above the plughole. If necessary, refill
with water.
12. Repeat the pressure surge until the blockage is
cleared.
Note:
Should you not be able to build up pressure, check
the air release valve
1
. Ensure that it is firmly screwed
onto the appliance.
