Storage
DANGER
Danger from fluids hazardous to health!
Risk of fatal injury if the mixer is used in fluids hazardous to health.
• Decontaminate the mixer after dismantling and before carrying out any other
work.
• Observe the specifications provided by work regulations. The operator must
make sure that personnel have received and read work regulations.
WARNING
The propeller blade has sharp edges!
Sharp edges can form on the propeller blades. There is a risk of limbs being severed.
Wear safety gloves to protect against cuts.
CAUTION
Total damage from to moisture ingress
Moisture ingress in the connection cable damages the connection cable and the
mixer! Never immerse the end of the connection cable in a fluid and firmly seal it
during storage.
Newly supplied mixers can be stored for one year. Contact customer service before
storing the mixer for more than one year.
The following must be observed as regards storage:
ƒ
Place the mixer (horizontally) on a solid surface
and secure it against slipping and
falling over!
CAUTION! Do not set the mixer down on the propeller. Doing so will damage the
propeller or the shaft! In the case of larger propeller diameters, ensure an appro-
priate platform is provided.
ƒ
The max. storage temperature is -15 °C to +60 °C (5 °F to 140 °F) at a max. relative
humidity 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.
ƒ
Do not store the mixer in rooms in which welding work is carried out. The resulting
gases or radiation can corrode the elastomer parts and coatings.
ƒ
Protect the connection cable against kinking and damage.
ƒ
Protect the mixer from direct sunlight and heat. Extreme heat can cause damage to
the propeller and the coating!
ƒ
Turn the propeller at regular intervals (twice a year). This prevents locking of the
bearings and renews the lubrication film of the mechanical seal.
WARNING! There is
a risk of injury from sharp edges on the propeller!
ƒ
Elastomer parts and the coating are subject to natural brittleness. Contact customer
service if the mixer has to be stored for more than 6 months.
After storage, remove any dust and oil from the mixer and check the coating for dam-
age. Repair damaged coatings before further use.
