3 Transport and interim storage
3.1 Shipping The pump is enclosed in a box or lashed to a pallet ex works and is pro-
tected against dirt and moisture.
Transport inspection On arrival, inspect the pump immediately for any transport damage.
If damage is found, the necessary procedure involving the forwarding
agent must be taken within the specified period.
Storage Before installation, the pump must be kept dry, frost-free and pro-
tected from mechanical damage.
CAUTION! Risk of damage due to incorrect packaging!
Ifthepumpistransportedagainatalatertime,itmustbepackaged
so that it cannot be damaged during transport.
• Use the original packaging for this, or choose equivalent packag-
ing.
3.2 Attachment WARNING! Risk of personal injury!
Improper transport can lead to personal injury.
• Thepumpmustbetransportedusingapprovedloadbearingequip-
ment. This is to be attached to the pump flanges and, if necessary,
to the outer motor diameter (safeguarding against slipping
required!).
• The transport eyes on the motorare only for guiding while bearing
the load (Fig. 4).
• To lift with a crane, the pump must be supported by suitable belts,
as shown. Place loops around the pump which tighten from the
pump's own weight.
• The transport eyes on the motor are only for transporting the
motor, and are not approved for transporting the complete pump
(Fig. 5).
WARNING! Risk of injury due to the weight of the pump!
The pump itself and the parts of pump can be extremely heavy.
Falling parts pose a risk of cuts, crush injuries, bruises or impacts,
which may lead to death.

ing.
• Never stand underneath a suspended load.

4Intendeduse
Purpose The glanded pumps of the IL (Inline), DL (Double) and BL (Monobloc)
series are meant to be used as circulation pumps in building services.
Fields of application They may be used for:
• Hot-water heating systems,
• Cooling and cold water circulation systems,
• Process water systems,
• Industrial circulation systems,
• Heat carrier circuits.
Restrictions Typical installation locations are technical rooms within the building
with other domestic installations. Installing the device directly in
other used rooms (residential and work rooms) is not intended.
For these series outdoor installation is only possible with the corre-
sponding special versions (motor with standby heating and fan cover
protective roof, see section 7.3 on page 32).
CAUTION! Risk of damage!
Impermissible substances in the fluid can destroy the pump. Abra-
sive solids (e.g. sand) increase pump wear.
Pumps without an Ex certificate are not suitable for use in poten-
tially explosive areas.
• The correct use of the pump/installation also includes following
these instructions.
• Any other use is considered to be incorrect use.
