English
Children must be supervised to ensure that they
do not play with the device.
• If hot or cold components of the product or sys -
tem pose a danger, it is the customer's responsi -
bility to guard them against being touched.
• Guards protecting against touching moving com -
ponents (such as the coupling) must not be
removed whilst the product is in operation.
• Hazardous fluids (e.g. from the shaft seals) which
have leaked (which are explosive, toxic or hot)
must be eliminated so that no danger to persons
or to the environment arises. National statutory
provisions must be respected.
• Highly flammable materials are always to be kept
at a safe distance from the product.
• Danger from electrical current must be eliminated.
Local directives or general directives (e.g. IEC, VDE
etc.) and instructions from energy supply compa -
nies must be adhered to.
2.6 Safety instructions for installation and
maintenance work
The operator must ensure that all maintenance
and installation work is carried out by authorised
and qualified personnel, who are sufficiently
informed from their own detailed study of the
installation and operating instructions.
Work on the product or system must only be car -
ried out when it is at a standstill. Compliance with
the procedures described in the installation and
operating instructions for shutting down the
product/system is mandatory.
Immediately on conclusion of the work, all safety
and protective devices must be put back in posi -
tion and recommissioned.
2.7 Unauthorised modification and manufacture of
spare parts
Unauthorised modification of components and
use of unauthorised spare parts will impair the
safety of the product/personnel, and will render
the manufacturer's declarations regarding safety
void.
Modifications to the product are only permissible
following consultation with the manufacturer.
Original spare parts and accessories authorised by
the manufacturer ensure safety.
The use of other parts absolves the manufacturing
company of any and all liability.

2.8 Improper use

The operational reliability of the supplied product
is only guaranteed if the requirements set out in
Section 4 of the installation and operating
instructions are complied with. The limit values
must on no account fall below or exceed the val -
ues specified in the catalogue or data sheet.

3 Transport and temporary storage

When receiving the product, check that it has not
been damaged during transport. If any damage is
found, take all necessary measures with the carrier
in the time provided.
The pressure-boosting system is delivered on a
pallet. It is protected from moisture and dust by
transparent plastic shrink-wrap.
The transportation and storage instructions
located on the packaging must be observed.
The system must be transported using a lifting
device suitable for carrying the load.
WARNING!
The static stability of the device must be taken
into account because, due to the pumps' design,
the system's centre of gravity shifts towards its
upper part.
Maintenance must be performed by qualified
personnel using suitable and authorised equip -
ment. Lifting straps must be fastened to the eye
bolts designed for this purpose or placed around
the steel baseplate.
The collector tanks are not suitable for handling
the pressure-boosting system and must not be
used to fix loads.
The stickers attached to the collector tanks pro -
vide a reminder of these instructions (Fig. 4).
CAUTION! Risk of damage to the installation
If the delivered material is to be installed at a
later date, store it in a dry place and protect it
from impacts and any external influences
(humidity, frost etc.).
Temperature range for transport and storage:
-30 °C to +60 °C
Handle the product with care so as not to damage
it prior to installation.

4 Intended use

The key function of the pressure-boosting system
is to ensure that a mains water supply with insuf -
ficient or no pressure is pressurised and remains
pressurised. The speed variators integrated into
the pumps and the integrated electronic control
system enable the mains to be kept at a constant
pressure no matter the flow rate.
It is used for:
• Drinking water supply systems, particularly in
high-rise apartment buildings, hospitals, indus -
trial and administrative buildings and fulfils the
following standards and directives relating to
design, function and requirements:
• DIN 1988 (for Germany)
• DIN 2000 (for Germany)
• EU Directive 98/83/EC
• Drinking Water Directive – TrinkwV2001
(for Germany)
• Industrial water supply and cooling systems
• Irrigation and sprinkling systems
