Uni cistern
Uni cistern
The Uni cistern from TECE is a universally usable stand-
ard cistern. By using dierent frames, the cistern can be
installed in dry or wet-wall constructions. The cistern is
always equipped with the same internal technology and is
therefore compatible with all TECE flush plates. The univer-
sality of the cistern results in a clear product range, simple
stock-keeping and spare parts supply.
Features of the cistern:
• Pre-assembled and sealed
• Can be combined with all TECE flush plates
• Single or dual-flush systems available
• Robust lever mechanism
• -litre safety tank: enough water when needed
• Flush volume adjustment for every application:
. and  litres,
 and  litres,
. and  litres or
 and  litres.
• Cistern tank made of impact-resistant plastic
• Easy to install
• Self-explanatory technology

Tank
As the tank volume is  litres, there is always plenty of
water for flushing. Even after flushing with the large flush
volume, water is always available for a follow-up flush. The
tank is made of impact-resistant plastic and is insulated
against condensation water.
A 2 drain valve
The current A  drain valve has been installed in TECE
cisterns since .

Dual-flush technology
During everyday use, a considerable amount of potable
water is used to flush toilets. Here, the intelligent solu-
tions from TECE can make an active contribution to saving
water. With dual-flush technology, the small flush volume
is set to  litres, and the large flush volume can be set to
.//. or  litres. The default setting for the dual-vol-
ume flush is litres for the large flush volume and litres
for the small flush volume.
Single-flush technology
Single-flush technology is also possible with TECE cisterns
and TECE drain valves. However, with this flush option,
only the large flush volumes of .//. or  litres are
available.
General information
Due to the easily adjustable drain valve settings, the flush
volumes can be adapted to each specific situation. In the
new building sector with adapted pipelines, slopes and
when using a . litre ceramic, the . litre economy flush
can be used in combination with the  litre flush. However,
pipe systems are often installed which need a larger flush
volume to ensure that they work correctly. In this case,
flush volumes of up to  litres can be chosen to ensure
this.

Setting the flush volumes
The flush volume is adjusted centrally via an adjustment
slide on the back of the drain valve. The adjustable flush
quantities are clearly marked on the valve.

Throttle set
If the flushing of a toilet ceramic is not adequate, the flush-
ing pressure can be reduced or increased with the help of
the throttle set.
The throttle set includes eight dierent throttles:
Brown: mm diameter (approx. % flushing pressure)
Red: mm diameter (approx. % flushing pressure)
Yellow: mm diameter (approx. % flushing pressure)
Blue: mm diameter (approx. % flushing pressure)
Green: mm diameter (approx. % flushing pressure)
Grey: mm diameter (approx. % flushing pressure)
Black: mm diameter (approx. % flushing pressure)
White: mm diameter (approx. % flushing pressure)
Reducing the flushing pressure:
The throttle set can be used to reduce the flushing pres-
sure if water sprays out of the toilet ceramics. To control
the flushing pressure, a throttle with a smaller internal
diameter can be used.
Increasing the flushing pressure:
If the toilet ceramics are not being cleaned correctly, 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 drain valve.
