Storage
DANGER
Danger due to fluids which are hazardous to health!
Decontaminate the mixer after removal and before carrying out any other work.
There is a risk of fatal injury. Observe the specifications in the work regulations. The
operator must ensure that the personnel have received and read the work regula-
tions.
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 device for more than one year.
When storing the pump, please note the following points:
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). The max. relative
humidity is 90 %, non-condensing. We recommend frost-proof storage. Ambient
temperature: 5 to 25 °C (41 to 77 °F), relative humidity: 40 to 50 %.
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. Maintain a constant bend
radius!
ƒ
Protect the PUR and GRP propeller from direct exposure to sunlight. The extreme
heat can cause damage to the propeller!
ƒ
Turn the propeller at regular intervals (twice a year). This prevents the bearings from
jamming and renews the lubrication film on 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 coatings for dam-
age. Repair damaged coatings before further use.
