Fig. 2: Attachment point
▪ Adhere to the applicable national safety regulations.
▪ Use legally specified and approved lifting gear.
▪ Select the lifting gear based on the existing conditions
(weather, attachment point, load, etc.).
▪ Only attach the lifting gear to the attachment point. Fix
with a shackle.
▪ Use lifting equipment with sufficient bearing capacity.
▪ The stability of the lifting equipment must be ensured
during operation.
▪ When using lifting equipment, a second person must be
present to coordinate the procedure if required (e.g. if
the operator's field of vision is blocked).

Storage

DANGER
Danger due to fluids hazardous to health!
If the pump is used in fluids hazardous to health, de-
contaminate the pump after dismantling and before
carrying out any other work! There is a risk of fatal in-
jury! Observe the specifications in the work regula-
tions! The operator must make sure that the person-
nel have received and read the work regulations!
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction
port. There is danger of limbs being severed! Protect-
ive gloves must be worn to protect from cuts.

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. Con-
tact 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 sur-
face 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-con-
densing. 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.
WARNING! 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 damage. Repair damaged
coatings before further use.
