reached (Fig. 7, lower position (14)). The system must then be switched off by the control unit after a
time delay (maximum 180s) defined on the control unit has elapsed. If the water level in the tank rises
again, the float switch emits a signal again after reaching the corresponding switching level (Fig. 7,
upper position (13)). The system can then, again after a time delay (at least 10s), be switched on by
the control in the control unit.
< ! > VORSICHT! Low water in the tank can cause dry running in the pressure
boosting system. The float switch integrated in the tank should be connected to the
control device in order to avoid damage to the pressure boosting system and/or to
the pumps!
In the case of systems for fire extinguishing operation, fire prevention code stipulations may however
prohibit the use of low-water signal transmitters to switch off the pressure boosting system in the event
of fire. These stipulations will take precedence in all cases!

Installation and electrical connection
7.4 Preparations for installation
The Wilo break tank is to be set up as close as possible to the pressure boosting system that is to be
connected to it. If any height compensation is necessary, then a corresponding base pedestal (Figs. 5a
and 5b (31)) is to be set up. The following basic prerequisites are to be complied without fail:
The break tank should be set up in a well-ventilated, frost-free room.
The installation surface must be horizontal and flat. The baseplate of the tank must be supported
across its entire surface.
The bearing surface must be able to bear sufficient loads in terms of statics in order to ensure that,
at a minimum, the maximum filling quantity can be supported safely.
The break tank must remain accessible for maintenance work, even after the installation has been
completed. (at least 600 mm above the tank, 1000 mm at the operating side).
WARNING! Danger of injury and danger of damage to the tank!
The cover of the break tank cannot be walked on! Non-permitted loads on the cover
can lead to destruction.
7.5 Hygiene (TrinkwV 2001)
The Wilo break tank is in compliance with the valid rules of technology and is designed for utilisation
with potable water applications. All of the materials used are accordingly suitable for such applications.
Please take into account that when used and operated in the potable water sector, the entire potable
water supply system needs to be handed over to the operator in a perfect state of hygiene. In addition,
the obligations arising from statutes (e.g. TrinkwV, AVBWasserV, etc.) and the recognised rules of
technology (e.g. DIN1988, VDI6023, DIN EN1717, DIN EN 806, DVGW worksheets, etc.) are also to
be observed.
WARNING! Contaminated potable water is a health hazard!
Flushing the pipes and the system reduces the risk of affecting the quality of the
potable water!
The water must be completely replaced after a longer period of system standstill!
Stagnating water in supply pipes (stub lines) must be avoided.
If stub lines cannot be avoided, they must be adequately flushed regularly by
means of suitable procedures!
During operation, it must also be ensured that a regular check of the hygienic condition and, if
necessary, mechanical cleaning and disinfection are carried out. If necessary, an appropriate specialist
company should be consulted or engaged.
