CAUTION
Defective macerator due to incorrect storage!
Storage without the use of transportation bolts dam-
ages the macerator! Always screw on the transporta-
tion bolts before storing the pump.
CAUTION
Defective macerator due to objects lying
around!
Hard objects can damage the macerator! When set-
ting down, ensure that no objects come into contact
with the macerator.
CAUTION
Total damage due to moisture ingress
Moisture ingress in the power supply cable damages
the power supply cable and the pump! Never im-
merse the end of the power supply cable in a fluid
and firmly seal it during storage.
Newly supplied pumps can be stored for one year. Contact cus-
tomer service to store the pump for more than one year.
The following must be observed for storage:
ƒ
Place the pump upright (vertical) on a firm bearing surface and
secure it against slipping and falling over!
ƒ
The max. storage temperature is -15 °C to +60 °C (5 °F to
140 °F) at a max. relative humidity of 90 %, non-condensing.
Frost-proof storage at a temperature of 5 °C to 25 °C (41 °F to
77 °F) with relative humidity of 40 % to 50 % is recommen-
ded.
ƒ
Do not store the pump in rooms in which welding work is car-
ried out. The resulting gases or radiation can corrode the
elastomer parts and coatings.
ƒ
Seal the suction and pressure connection tightly.
ƒ
Protect power supply cables against kinking and damage.
ƒ
Protect the pump from direct sunlight and heat. Extreme heat
can cause damage to the impellers and the coating!
ƒ
Elastomer parts and the coating are subject to natural brittle-
ness. Contact customer service if the pump must be stored for
more than 6 months.
After storage, remove any dust and oil from the pump and check
the coating for damage. Repair damaged coatings before further
use.

6.1
Personnel qualifications
ƒ
Electrical work: A qualified electrician must carry out the elec-
trical work.
ƒ
Installation/dismantling: The technician must be trained in the
use of the necessary tools and fixation materials for the relev-
ant construction site.
6.2
Installation types
ƒ
Vertical stationary wet well installation with suspension unit
ƒ
Vertical portable wet well installation with pump support foot
The following installation types are
not
permitted:
ƒ
Dry well installation
ƒ
Horizontal installation
6.3
Operator responsibilities
ƒ
Observe locally applicable accident prevention and safety reg-
ulations of trade associations.
ƒ
Observe all regulations for working with heavy loads and un-
der suspended loads.
ƒ
Provide protective equipment and ensure that the protective
equipment is worn by personnel.
ƒ
Observe local sewage technology regulations for the opera-
tion of sewage systems.
ƒ
Avoid pressure surges!
Pressure surges can occur in long pressure pipes with steep
terrain. These pressure surges can lead to the destruction of
the pump!
ƒ
Ensure the cooling time of the motor depending on the oper-
ating conditions and the size of the pump chamber.
ƒ
Structural components and foundations must be of sufficient
stability in order to allow the device to be fixed securely and
functionally. The operator is responsible for the provision and
suitability of the structural component/foundation!
ƒ
Check that the available consulting documents (installation
plans, design of the operating space, inflow conditions) are
complete and correct.

Installation
DANGER
Risk of fatal injury due to dangerous lone
working practices!
Work in chambers and narrow rooms as well as work
involving risk of falling are dangerous work. Such
work may not be carried out autonomously! A second
person must be present for safety reasons.
