Installation and electrical connection
CAUTION
Total damage due to moisture ingress
Moisture ingress in the power supply cable damages the power supply cable and the
pump! Never immerse 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 customer service to store
the pump for more than one year.
The following must be observed for storage:
▪ Place the pump upright (vertical) on a firm bearing surface and secure it against slip-
ping and falling over!
▪ The max. storage temperature is -15 °C to +60 °C (5 °F to 140 °F) at a max. relative hu-
midity 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 pump in rooms in which welding work is carried out. The resulting
gases or radiation can corrode the elastomer parts and coatings.
▪ Seal the suction and pressure connection tightly.
▪ Protect power supply cables against kinking and damage.
▪ Protect the pump from direct sunlight and heat. Extreme heat can cause damage to the
impellers and the coating!
▪ Impellers must be turned by 180 ° at regular intervals (3 – 6 months). This prevents
locking of the bearings and renews the lubrication film of the mechanical seal. WARN-
ING! There is a risk of injury due to sharp edges on the impeller and suction port!
▪ Elastomer parts and the coating are subject to natural brittleness. 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 dam-
age. Repair damaged coatings before further use.
▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials for the relevant construction site.
▪ Vertical stationary wet well installation
▪ Vertical portable wet well installation
▪ Vertical stationary dry well installation

▪ Observe locally applicable accident prevention and safety regulations of trade associ-
ations.
▪ 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.
▪ Observe local sewage technology regulations for the operation of sewage systems.
▪ 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!
