3. SAFETY INSTRUCTIONS
WARNING: Always disconnect the power supply prior to performing any installation or connec-
tion operations!
All installation and wiring work at the unit must be carried out only in a safe (idle) condition.
The appliance may be connected and operated by qualified personnel only. Make sure to adhere to
valid local safety regulations.
The
control units are neither splash- nor drip-proof. Therefore, they must be mounted in a dry place.
Do not interchange the connections of the sensors and the 230V connections under any circumstances! Inter-
changing these connections may result in life endangering
electrical hazards
or the destruction of the appliance
and the connected sensors and other appliances.

OUNTING AND
H
YDRAULIC CONNECTIONS
The FBC-HC can be installed directly on a dry, sufficiently firm background
(wall). Remove the front part of the heat insulation box (Fig.2_10). Using
screws and dowels fit the back-part of the WDS (Fig.2_9) together with the
brackets to the wall.
Please pay attention not to damage or brake the cables of the control, pump,
valve drive or temperature limiter while assembling. The cables must be in-
stalled without tension. The cables will be fixed by means of the device for
strain relief at the heating controller.
The hydraulic connections are to be made as shown in Fig.3.
