Installation and electrical connection
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 portable wet well installation
The following installation types are not permitted:
▪ Vertical stationary wet well installation with suspension unit
▪ Vertical stationary dry well installation
▪ Horizontal installation
▪ Observe the locally applicable professional and trade association accident prevention
and safety regulations.
▪ 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 regulations on the latest technology for the disposal of wastewater and
sewage (without faeces).
▪ Avoid pressure surges!
▪ Check that the available consulting documents (installation plans, design of the operat-
ing space, inflow conditions) are complete and correct.
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 dan-
gerous work. Such work may not be carried out autonomously! A second person
must be present for safety reasons.
WARNING
Hand and foot injuries due to lack of protective equipment!
Danger of (serious) injuries during work. Wear the following protective equipment:
• Safety gloves for protection against cuts
• Safety shoes
• Safety helmet must be worn if lifting equipment are used!
