3. TRANSPORT AND INTERIM STORAGE
The pressure boosting system is delivered on a pallet and is pro-
tected from dust and moisture by transparent plastic wrap-
ping.
CAUTION! Risk of damage! Transport only using a prop-
erly approved load hoist.
When hoisting with a crane, use the transport lugs on
the pumps (see Fig. 10)
The pipes are not designed for hoisting of the pressure
boosting system and must never be used for securing or
fastening during transit.
CAUTION! Risk of leakage!
Loading of the pipes in transit can result in leaks!
Immediately check the product for any transit damage on
arrival. If any damage is found, it is to be reported to the trans-
port company immediately.
CAUTION! Risk of damage to the product!
If the unit is to be installed later, then it must be stored in
a dry location. Protect the product from impacts/shock
and other effects (moisture, freezing etc.). Handle the
unit with care.
4. INTENDED USE (APPLICATION)
The main function of the pressure boosting system is to increase
and maintain the pressure in water supply networks which
have inadequate or no pressure.
It is used for water supply in residential houses and small apart-
ment buildings. The fluids pumped through the unit are clear,
non-aggressive
liquids
mixtures ...).
The switchgear is used for automatic control, monitoring and
automatic protection of the pressure boosting system.
Water is supplied to the pressure boosting system through the
municipal water supply network or from a replenishment reser-
voir.
If there are pressure fluctuations in the suction line of more than
1 bar, a pressure reducer must be used. The output pressure
downstream from the pressure reducer (the secondary pres-
sure) should be used as the basis for calculating the total deliv-
ery head of the pressure boosting system.

6. DESCRIPTION AND FUNCTION
6.1 General description
The pressure boosting system is a completely pre-assembled
compact unit delivered ready for connection. All that remains
to be done is to connect it to the suction and pressure pipes,
the diaphragm pressure vessel, the protection against low
water level and the electricity supply.
Any accessories ordered are delivered separately.
When connecting to the public water supply network, be sure
to comply with the applicable regulations and standards, and
the requirements of the water supply company. In addition,
make allowance for local conditions (e.g. an inlet pressure that
is too high or irregular might require the installation of a pres-
sure reducer under certain circumstances).
