Siemens Building Technologies Electric actuators for butterfly valves CM1N4506en
HVAC Products 07.06.2004
The angle of rotation is factory-set to 90°. However, the angle can be changed to
between 70° and 180°. This may be necessary when using non-Siemens valves.
Special notes on this subject will be found in the mounting instructions for the ASK40
and ASK41 (mounting kits for non-Siemens valves).
Maintenance
The actuators require no maintenance.
When servicing the valve and/or actuator: switch OFF the pump and power
supply, close the main shut-off valve in the pipework, release pressure in the
pipes and allow them to cool down completely.
If necessary, disconnect electrical connections from terminals.
Disposal The device may not be disposed of together with domestic waste. This applies in
particular to the PCB.
Legislation may demand special handling of certain components, or it may be sensible
from an ecological point of view.
Current local legislation must be observed.
Warranty
The technical data given for these applications is valid only in conjunction with the
Siemens valves (butterfly and slipper valves) and third-party valves for use with the
ASK40 / ASK41, as described under "Compatibility". The use of third-party valves
other than those recommended by Siemens invalidates the warranty.
