Installation Notes
The actuator may not be lagged.
For notes on electrical installation, see «Connection terminals» resp. «Connection
diagrams»
Maintenance Notes
The valves and actuators are maintenance-free.
The low friction and robust design make regular servicing unnecessary and ensure a
long service life.
The valve stem is sealed from external influences by a maintenance-free gland.
Always disconnect power before fitting or removing the terminal housing.
Under operating conditions within the limits defined by the application data, the
actuator will become hot, but this does not represent a burn risk. Always
maintain the minimum clearance specified, refer to «Dimensions».
