Installation and electrical connection

CAUTION
Defective macerator due to incorrect storage!
Storage without the use of transportation bolts damages the macerator! Always screw on
the transportation bolts before storing the pump.
CAUTION
Defective macerator due to objects lying around!
Hard objects can damage the macerator! When setting down, ensure that no objects
come into contact with the macerator.
CAUTION
Total loss due to moisture penetration
Moisture penetration in the power supply cable damages the power supply cable and the
pump! Never immerse the end of the power supply cable in a liquid and tightly seal during
storage.
Newly delivered pumps can be stored for a year. Regarding storage for more than one year
contact customer service.
Observe the following points regarding storage:
▪ Place the pump upright (vertical) on a firm bearing surface and secure it against slipping
and falling over!
▪ 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 recommended.
▪ Do not store the pumps in rooms in which welding works are carried out. The resulting gases
or radiations could corrode the elastomer parts and coatings.
▪ Tightly seal suction and pressure connection.
▪ Protect power supply cable against kinking and damage.
▪ Protect pump from direct sunlight and heat. Extreme heat may lead to damage to the im-
pellers and coating!
▪ The elastomer parts and coatings become brittle over time. When stored for more than
6 months, customer service must be consulted.
Following storage, clean the dust and oil from the pump and check the coating for damage.
Repair damaged coatings before further use.
▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation-/dismantling work: The technician must be trained to handle the necessary tools
and required fastening materials for the present building site.
▪ Vertical stationary wet well installation with guide system
▪ Vertical portable wet well installation with pump foot
The following installation methods are not permissible:
▪ Dry well installation
▪ Horizontal installation
▪ Locally applicable accident prevention and trade association safety provisions must be ob-
served.
▪ Observe all regulations for working with and underneath heavy suspended loads.
▪ Make available protective equipment and ensure that the personnel wear the protective
equipment.
▪ Observe the local regulations of sewage technology for the operation of sewage systems.
