Installation

The pipework has to be flushed thoroughly before
installing the fitting. It must be observed that the
direction of flow conforms to the arrow on the valve
body.

6.1 Preparations
The position of the radiator and fitting have to be
determined first (specifications of the manufacturer
must be observed). In new buildings, the pipework for
the supply and return connection of the heating circuit
(middle connections of the fitting) is laid during the
construction phase.
The connection pipes laid into the wall are to be
insulated according to the German Energy Saving
Directive. This will also facilitate the connection of the
fitting. Suitable wall channels for the heating circuit
and surface temperature balance have to be created
(illustr. 7 and 8). Screw the mounting aid precisely onto
the unplastered wall (screws are not included in the
delivery). During pipework installation please observe
that pipes must run in parallel. The protruding pipes
have to be fixed in the mounting aid with the enclosed
diaphragm tailpipes (illustr. 9).
1. Slip diaphragm tailpipe onto the protruding pipe.
2. Insert the diaphragm tailpipe into the cut-out of the
mounting aid and push it down until stop.
The walls are plastered now. The wall channel must
not be plastered as the pipework for surface temperature
12
balance will only be installed after all plastering has
been completed. The pipework for surface temperature
balance is fixed in the mounting aid in the same way
(illustr.9).
NOTICE
Supply and return pipe connection
To guarantee a perfect function of the fitting, the
supply and return pipe connections must be strictly
observed.
