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 pro-
cedure if required (e.g. if the operator’s field of vision is blocked).

Storage
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction port. There is danger of limbs be-
ing severed! Protective gloves must be worn to protect from cuts.
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.
