• If hot or cold components of the product/system
pose a danger, it is the customer's responsibility to
guard them against being touched.
• Guards which protect personnel from coming into
contact with moving components (e.g. couplings)
must not be removed while the product is in oper-
ation.
• Hazardous fluids (i.e. which are explosive, toxic or
hot) which have leaked (e.g. from the shaft seals)
must be disposed of so that they pose no danger
to persons or to the environment. National statu-
tory provisions must be respected.
• Danger from electrical current must be eliminated.
Local directives or general directives [e.g. IEC, VDE
etc.] and instructions from local energy supply
companies must be respected.
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 having studied the Installation and oper-
ating instructions in detail. Work on the product/
unit must only be carried out when it is at a stand-
still. 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 per-
missible following consultation with the manu-
facturer.
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 for conventional use in accord-
ance with Chapter 4 of the Installation and oper-
ating instructions.
The limit values must on no account fall below or
exceed the values specified in the catalogue/data
sheet.

3 Transport and temporary storage
When you receive the device, check that it has not
been damaged during transport. If you notice a
fault, take all necessary action with the carrier
within the time allowed.
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 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
transport lugs designed for this purpose or
placed around the steel baseplate. A sticker on
the plastic shrink-wrap contains the safety
instructions (Fig. 2).
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. 3).
CAUTION! Risk of damage to the installation
If the equipment delivered must be installed at a
subsequent date, store it in a dry place and pro-
tect it from shocks and any other external
effects (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
Intended use of the pressure-boosting system is
to keep a fire hose cabinet pressurised and supply
it with water in order to protect buildings (hospi-
tals, apartment buildings, schools, industrial
premises, commercial centres, etc.).
The water supply to the pressure-boosting sys-
tem may be taken from the municipal water sup-
ply or from a replenishment reservoir.
