Chuck removal and attachment
Loosen the set screw with the allen key found on the chuck key. Remove chuck.
To attach align the set screw with the pilot hole on the shaft. Tighten the set screw
with the allen key found on the chuck key. Make sure that the set screw is firmly
tightened. Open the chuck fully to prepare for impeller attachment.
Impeller attachment
Insert the impeller shaft into the open chuck and adjust the impeller to a maximum
length of 25 cm (10 in) [of a 40 cm (16 in) shaft] to reduce vibration. The hollow
shaft allows the impeller shaft to come through the top of the stirrer if necessary.
Tighten the chuck's outer ring by hand and then secure with the chuck key. Install
the chuck guard over the chuck.

Environmental Operating Conditions

The stirrer must operate in the following conditions:
Indoors
1. Altitudes up to 2000 m (6500 ft).
2. Temperatures from 5
3. Maximum relative humidity 80% for temperatures up to 31
linearly to 50% relative humidity at (104
4. Pollution degree 2 in accordance with IEC 664.
" Normally only non conductive pollution occurs. Occasionally, however, tem-
porary conductivity caused by condensation must be expected."

General Operating Instructions

Make sure that the stirrer is securely mounted as specified in the installation
instructions. Also make sure that the impeller is securely attached in the de-
sired position.
Connect the power cord to a grounded supply.
The stirrer is now ready for use to mix liquids and liquid/solid solutions. The
operator, ensuring that all safety instructions are followed must determine ap-
propriate impeller and container specifications.
The stirrer can operate continuously if the torque demand falls below the con-
tinuous torque operation line (see Torque Capabilities). When using the torque
curve charts, should the ambient temperature be above 25°C, then the 40°C
continuous operation line must be used.
