5.3 Storage
NOTICE
Improper storage can lead to damage to the equipment.
Damage caused by improper storage is not covered by the guarantee or warranty.
▪Requirements at the storage location:
– dry
– clean
– well-ventilated
– free from vibrations
– free from humidity
– free from rapid or extreme changes in temperature
▪Store the product somewhere safe against mechanical damage.
▪Protect the bearings and couplings from sand, gravel and other foreign objects.
▪Lubricate the unit to prevent rust and bearing seizing.
▪Manually rotate the drive shaft several times once a week.
Storage for more than three months
Additional precautionary measures:
▪All rotating parts must be coated with a suitable protective medium to protect them
from rust.
▪If the pump is to be stored for more than a year, consult the manufacturer.
6 Installation and electrical con-
nection
6.1 Personnel qualifications
▪Electrical work: A qualified electrician must carry out the electrical work.
6.2 Operator responsibilities
▪Observe locally applicable accident prevention and safety regulations of professional
and trade associations.
▪Observe all regulations for working with heavy loads and under suspended loads.
▪Provide protective equipment and ensure that the protective equipment is worn by
personnel.
▪Avoid pressure surges!
Pressure surges can occur in long pressure pipes. These pressure surges can lead to the
destruction of the pump!
▪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!
▪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.
• The pump should only be installed after completion of all welding and soldering
work.
• Flush the pipe system if required. Dirt can cause the pump to fail.
▪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.
▪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.
▪A travelling crane or a device for attaching hoisting gear should be installed above the
set-up site of large pumps.
