–
free from rapid or extreme changes in temperature
ƒ
Store the product somewhere safe against mechanical damage.
ƒ
Protect the bearings and couplings from sand, gravel and other foreign objects.
ƒ
Lubricate the unit to prevent rust and bearing seizing.
ƒ
Manually rotate the drive shaft several times once a week.
Storage for more than three months
Additional precautionary measures:
ƒ
All rotating parts must be coated with a suitable protective medium to protect them from
rust.
ƒ
If the pump is to be stored for more than a year, consult the manufacturer.

Installation and electrical con-

6.1
Personnel qualifications
ƒ
Electrical work: A qualified electrician must carry out the electrical work.
6.2
Operator responsibilities
ƒ
Observe locally applicable accident prevention and safety regulations of professional and
trade associations.
ƒ
Observe all regulations for working with heavy loads and under suspended loads.
ƒ
Provide protective equipment and ensure that the protective equipment is worn by per-
sonnel.
ƒ
Avoid pressure surges!
Pressure surges can occur in long pressure pipes. These pressure surges can lead to the
destruction of the pump!
ƒ
Structural components and foundations must be of sufficient stability in order to allow
the device to be fixed in a secure and functional manner. The operator is responsible for
the provision and suitability of the building/foundation!
ƒ
Check that the available consulting documents (installation plans, design of the operat-
ing space, inflow conditions) are complete and correct.
6.3
Preparing the installation
WARNING
Risk of personal injury and property damage due to improper handling!
• Never set up the pump unit on unfortified surfaces or surfaces that cannot bear
loads.
• Flush the pipe system if required. Dirt can cause the pump to fail.
• Install only after completion of all welding and soldering work and after the pipe sys-
tem has been flushed, if required.
• Observe the minimum axial distance between a wall and the fan cover of the motor:
8 diameter of the fan cover
ƒ
The pumps (in the standard version) must be protected from the weather and installed in
a frost/dust-free, well-ventilated environment that is not potentially explosive.
ƒ
Mount the pump in a readily accessible place. This makes it easier to complete inspec-
tions, maintenance (e.g. mechanical seal change) or replacement in the future.
ƒ
A travelling crane or a device for attaching hoisting gear should be installed above the
set-up site of large pumps.
