Environmental Operating Conditions; General Operating Instructions - Caframo BDC1850 Handbuch

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 40
4. Pollution degree 2 in accordance with IEC 664.

General Operating Instructions

M ake 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.
If the stirrer is used for an extended period of time above the appropriate con-
tinuous temperature operation line (see Torque Capabilities), then it may shut
down. The stirrer may be started after it has cooled down.
