Setting the flush volumes
The flush volumes are adjusted centrally using an adjust-
ment slide on the rear of the drain valve. The flush volumes
which can be set are clearly marked on the valve.

Throttle set
Problems with the toilet ceramic not flushing correctly can
be resolved with the aid of a throttle set.
The throttle set includes eight different throttles:
Brown: 46 mm diameter (approx. 115% flush pressure)
Red: 42 mm diameter (approx. 110% flush pressure)
Yellow: 39 mm diameter (approx. 105% flush pressure)
Blue: 36 mm diameter (approx. 100% flush pressure)
Green: 34 mm diameter (approx. 95% flush pressure)
Grey: 32 mm diameter (approx. 85% flush pressure)
Black: 30 mm diameter (approx. 75% flush pressure)
White: 28 mm diameter (approx. 65% flush pressure)
Reducing the flush pressure:
The throttle set can be used to reduce the flush pressure
if water sprays out of the ceramic. To control the flushing
pressure, a throttle with a smaller internal diameter can be
used.
Increasing the flushing pressure:
If a toilet ceramic is not being correctly cleaned then the
flushing pressure for standard cisterns can be subse-
quently increased. To increase the flushing pressure, install
a throttle with a larger internal diameter or remove the
inserted throttle.
The flush flow throttle can be easily installed in the valve
seat of the drainage valve.
