WARNING
Risk to life and limb due to electric shock!
Prior to performing electrical work on the controller,
de-energise the system.
For more information, see enclosed installation and
operation instructions of the station controller.
Connect the fresh water station to the power supply
system (230 V, 50 Hz) only after completing all
installation work, filling and flushing.
This avoids an unintentional start of the motors.
The plug-in pump lines are permanently supplied with a
mains voltage of 230 V and cannot be switched off via
the controller.
The fresh water station is pre-wired in the factory. When using the circulation pump,
its connection can be obtained from the enclosed assembly instructions.
