Glossary
Accumulator
Pressure losses may occur in the piping system
downstream of the break tank package booster
set for fire fighting which may be caused by
leakage of small quantities of water. The
accumulator serves to compensate pressure losses
and minimises the frequency of starts of the break
tank package booster set for fire fighting.
Back-up system
The part of the fire-fighting system / break tank
package booster set for fire-fighting which
ensures the supply of fire-fighting water in the
event of a fire if the duty system fails (see also
duty system).
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
DIN 1988
German Standard which stipulates technical rules
for drinking water installations.
DIN14462
The fire-fighting systems/ break tank package
booster sets for fire fighting must comply with the
German standard for water conduits for fire
extinguishing.
Duty system
The active part of the fire-fighting system / break
tank package booster set for fire-fighting which
ensures the supply of fire-fighting water in the
event of a fire (see also back-up system).
Flushing
If the volume of the inlet line exceeds 1.5l and/or
the length of the inlet line ≥10×DN, a flushing
system must be provided. This will prevent
stagnating fluid handled and microbial
contamination of drinking water.
IE3
Efficiency class to IEC60034-30: 3=Premium
Efficiency (IE = International Efficiency)
Manual mode
Direct operation on the power supply network,
independently of the control unit.
Pump activation
Pump activation means that a pump is started up
by a starting signal from the pressure switch, from
a wall hydrant (limit switch) via remote ON/OFF, or
from the broken wire and short-circuit monitoring
relay.
Rainwater storage tank
Tank for collecting rainwater, for buried
installation or above-floor installation
Switchgear and controlgear assembly
Control cabinet with one or several control units/
switchgears and electrical equipment.

Design Fully automatic, ready-to-connect break tank package booster set for fire fighting
comprising two high-pressure centrifugal pumps (2) with redundant function, a
control cabinet (1) and a tank (4) for the hygienic separation of drinking water and
fire-fighting water. The modular design allows separating the break tank package
booster set for fire fighting into three modules (control cabinet with hydraulic unit,
tank and baseplate). Anti-vibration mounts are fitted at the pump feet and baseplate
(5).
Function The pump sets are started and stopped as a function of pressure via the electro-
mechanical control system. If the pressure drops below the set start-up pressure pE,
the pump sets are started up via the pressure switch. When consumption decreases
again, the pump sets are stopped as a function of pressure after the set after-run
period (up to 10minutes). Independently of the pressure switch, the break tank
package booster set for fire fighting can also be controlled via remote ON/OFF (e.g. a
switch in the wall hydrant). The pressure switch and remote ON/OFF input are
monitored for broken wires and short circuit. If a broken wire or short circuit are
detected, the break tank package booster set for fire fighting is started up
automatically and a fault is indicated.
In the event of a fire, pumping the fluid handled is of top priority. In automatic
mode, the protective features (dry running protection, motor protection) cannot be
enabled. If the motor protection switch trips, the motor will keep running on the
power supply network without further monitoring. A fault message is output.
The required quantity of the fluid handled is supplied via the float valve.
The float valve at the drinking water inlet is opened and closed fully automatically as
a function of the fill level in the tank. A float switch monitors for lack-of-water and
overflow, and signals such events to the control system. Power supply of the flushing
system and water level monitoring equipment is effected via terminals in the control
cabinet.

5.1 Checks to be carried out prior to installation
WARNING
Installation on mounting surfaces which are unsecured and cannot support the
load
Personal injury and damage to property!
▷Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class X0 to EN206-1.
▷The mounting surface must have set and must be completely horizontal and
even.
▷Observe the weights indicated.
NOTE
The anti-vibration mounts provide adequate insulation against solid-borne noise.
NOTE
Do not operate the break tank package booster set for fire fighting near living
quarters and/or sleeping quarters.
NOTE
Observe the installation requirements to DIN14462.
Before beginning with the installation check the following:
▪All structural work required has been checked and prepared in accordance with
the dimensions in the outline drawing.
▪The break tank package booster set for fire fighting can be operated on the
power supply network according to the data on the name plate.
(ðSection4.4,Page15)
▪The place of installation is frost-free.
▪The place of installation can be locked.
▪The place of installation is well-ventilated.
▪A suitably dimensioned drain connection (e.g. leading to a sewer) is available.
▪If the system is installed below the flood level, the country-specific drainage
regulations must be complied with.
▪If expansion joints are used, take note of their creep resistance. Expansion joints
must be easily replaceable.

5.2 Installing the break tank package booster set for fire fighting
DANGER
Microbial contamination of drinking water
Danger to life!
▷If the volume of the inlet line exceeds 1.5l and/or the length of the inlet line
≥10×DN, flush the inlet line at least 1× per week. (ðSection7.3.6,Page36)
CAUTION
Dirt in the break tank package booster set for fire fighting
Damage to the pump set!
▷Clean the tank before filling it.
▷Clean the tank and the integrated odour trap at least once a year.
NOTE
DIN1988 permits the installation of an unpressurised tank. The tank made of
polyethylene meets the requirements of EN1717 and EN13077, (overflow typeAB
air gap).
üThe packaging of the break tank package booster set for fire fighting has been
removed.
üSufficient clearance in all directions is provided for servicing work.
üAll structural work required has been checked.
üThe dimensions of the foundation are correct, and the concrete has set firmly.
üThe foundation is level.
1. Align the break tank package booster set for fire fighting horizontally.
ðStandard design: If necessary, insert shims, wedges or other supports under
baseplate sections designed to contact the floor.
ðVersion with feet (optional): Adjust the feet height.
2. Connect the mains water supply line and discharge line to the corresponding
distribution lines on the inlet side and discharge side. See DIN1988.
3. Mark the fastening hole positions on the foundation in accordance with the
outline drawing (other applicable documents).
4. Drill the holes (maximum diameter: 12mm).
5. Insert plug fixings of appropriate size.
