Maintenance notes
The SKC.. actuators are maintenance-free.
When servicing the actuator:
· Switch off pump of the hydronic loop
· Interrupt the power supply to the actuator
· Close the main shutoff valves in the system
· Release pressure in the pipes and allow them to cool down completely
· If necessary, disconnect electrical connections from the terminals
· The actuator must be correctly fitted to the valve before recommissioning.
Recommendation SKC6..: trigger stroke calibration.
«Replacement parts», see page 18.
A damaged housing or cover represents an injury risk
· NEVER uninstall an actuator from the valve
· Uninstall the valve-actuator combination (actuating device) as a complete
device
· Use only properly trained technicians to uninstall the unit
· Send the actuating device together with an error report to your local Siemens
representative for analysis and disposal
· Properly mount the new actuating device (valve and actuator)
Parts could fly ultimately resulting in injuries from uninstalling an actuator with a
damaged valve housing due to the tensioned return spring.
Disposal The device contains electrical and electronic components and must 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 relating to specific applications are valid only in conjunction with the
valves listed in this Data Sheet under «Equipment combinations», page 3.
The use of the actuators in conjunction with third-party valves invalidates all
claims under Siemens Switzerland Ltd warranty.
