2.4
Responsible working
The safety hints mentioned in these operating instruc-
tions, the current national rules for the prevention of
accidents as well as any internal working, operating
and safety regulations of the owner must be ob-
served.
2.5
Safety hints for the user/operator
!
If hot or cold machine parts lead to dangers, these
parts must be protected against accidental contact
at the site.
!
Protection against accidental contact for moving
parts must not be removed when the machine is
in operation.
!
When operating pump aggregates in a dust-laden
environment (e.g. milling, chipboard manufacture,
bakeries), the surface of the pumps and motors
must be cleaned at regular intervals, depending
on local conditions, in order to maintain the cool-
ing effect and eliminate the possibility of sponta-
neous combustion. Please also see explosion pro-
tection regulations (BGR 104).
!
Leakages (e.g. of the shaft seal) of dangerous
materials to be handled (e.g. explosive, toxic, hot)
must be discharged so as not to result in danger
to persons and the environment. Legal stipula-
tions are to be observed.
!
Dangers by electrical energy are to be excluded
(for details with regard hereto, please refer e.g. to
the regulations of the VDE and the local energy
supply associations).
2.6
Safety hints for maintenance, inspection and mo-
unting operations
The customer shall see to it that all maintenance, in-
spection and mounting operations are performed by
authorized and qualified expert personnel who have
sufficiently informed themselves by thoroughly study-
ing the operating instructions.
Basically, operations at the machine must be per-
formed during standstill only. The mode of operation
for stopping the machine described in the operating
instructions must by all means be observed.
Pumps or aggregates handling noxious liquids must
be decontaminated.
Immediately upon completion of the operations, all
safety and protective devices must be mounted and
made operational again.
Prior to restarting, the items listed in Chapter “Prepa-
ration for start-up” are to be observed.
2.7
Independent reconstruction and spare parts pro-
duction
Reconstruction of or changes to the machine are only
admissible after consultation with the manufacturer.
Original spare parts and accessories authorized by
the manufacturer serve safety purposes. The use of
other parts may cancel the liability for the conse-
quences resulting therefrom.
2.8
Inadmissible modes of operation
The operating safety of the machine supplied is only
ensured with due application according to Chapter 1
“General” of the operating instructions. The limit val-
ues given in the data sheet must by no means be ex-
ceeded.
2.9
Operation in potentially explosive environments
Observe the instructions of the ATEX additional oper-
ating manual when operating the pump respectively
aggregate in potentially explosive environments.

Transport and intermediate storage
3.1
Packing
The symbols applied to the packing must be ob-
served.
During transportation and storage, suction and outlet
side and auxiliary connections of the pump must be
closed with plugs. During installation of the pump ag-
gregate, the plugs must be removed.
3.2
Transportation
The pump or pump aggregate is to be safely trans-
ported to the place of installation, if required by
means of lifting gear.
The regulation for lifting loads in accordance with
VBG 9a must be observed. Crane and sling
equipment must be adequately dimensioned.
Sling equipment must not be secured to the lifting
eyes of the motor, except as additional protection
against overturning in the event of nose-
heaviness.
When transporting the pump by crane, place the
stopper ropes safely around the suction casing. With
complete pump aggregates, an additional rope must
be slung around the drive engine.
The stopper ropes have to be slung around the pump
respectively pump aggregate so that these are ex-
actly balanced when lifted.
Transportation to and at the installation site
Make sure, that the unit is transported safely and in a
stable position. Overturning due to nose-heaviness
must be prevented.
Transport damages
Check the pump for damage on
receipt. Any damage detected must
be notified immediately.
