When removing the cover hood, ensure that the con-
nection cable between the operating panel and the
central unit is only approx. 1m long when the oper-
ating panel is already connected. When removing
the hood, the connection cable must not be strained.
To remove the cover hood completely, the connection
cable on the central unit or on the operating panel
must be removed.
- Before commissioning the system, check that the
pumps can run freely.
- Before commissioning the system, tighten the ter-
minals.
The supply lines must have the relevant thickness.
For more information, see technical data - max. power
intake.
All other connections should be created directly on
the microprocessor control PCB or are factory-fitted
230V / 50Hz
(see the next few pages).
