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 circulation 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 circulation station is pre-wired in the factory.
