▪ 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
Attached macerator: sharp edges on the cut-
ting plate and rotating blade!
The macerator can cause amputation of limbs! Wear
safety gloves to protect against cuts and never reach
into the macerator!
CAUTION
Defective macerator due to incorrect storage!
Storage without the use of transportation bolts dam-
ages the macerator! Always screw on the transporta-
tion bolts before storing the pump.
CAUTION
Defective macerator due to objects lying
around!
Hard objects can damage the macerator! When set-
ting down, ensure that no objects come into contact
with the macerator.
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.

Installation and electrical connection

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!
▪ 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.
