serve the following instructions:
ƒAdhere to the prescribed sequence of work steps.
ƒUnscrew the screw plugs slowly, but never unscrew them completely. As soon as
pressure is released (audible whistling or hissing of air), stop turning the screw plug
any further.
WARNING!Hot operating fluids can also spray out when pressure is released. This
can result in scalding! To avoid injuries, allow the motor to cool down to the am-
bient temperature before carrying out any work!
ƒWhen the pressure has been completely released, fully unscrew the screw plug.

Monitoring of motor compartment
The motor compartment monitoring protects the motor winding from short-circuits.
The moisture is measured by an electrode.
Monitoring the motor compartment and sealing chamber
The motor compartment monitoring protects the motor winding from short-circuits.
Sealing chamber control detects fluid ingress through the mechanical seal on the fluid
side. In each case, the humidity is recorded by an electrode in the motor compartment
and sealing chamber.
NOTICE!The Ex version does not feature this monitoring unit!
Monitoring of motor winding
The thermal motor monitoring protects the motor winding from overheating. Temper-
ature limiting with bimetallic strip is fitted as standard.
As an option, the temperature can also be measured with a PTC sensor. The thermal
motor monitoring can also be designed as temperature control. This allows the meas-
urement of two temperatures. When the low temperature is reached, an automatic re-
activation can be initiated after cooling the motor. When the high temperature is
reached, the unit must deactivate with reactivation lock.

5.3 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:
ƒPlace 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.
ƒThe 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.
ƒDo 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.
ƒProtect the connection cable against kinking and damage.
ƒProtect the mixer from direct sunlight and heat. Extreme heat can cause damage to
the propeller and the coating!
ƒTurn 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!
ƒElastomer 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.
