When servicing the actuator:
•
Switch off power
•
If necessary, disconnect the terminals
•
The actuator must only be commissioned with a correctly mounted valve in place!
The SSC... actuators cannot be repaired. They must be replaced as a complete unit.
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 (

, leakage rates, noise levels, service life, etc.) relating to
specific applications are valid only in conjunction with the Siemens valves listed in this
Data Sheet under «Equipment combinations».
The use of the SSC… actuators in conjunction with third-party valves invalidates
any warranty offered by Siemens Building Technologies / HVAC Products.
