During installation:
�
Set the unit in SERVICE MODE when the modulating by-pass valves
are blocking the installation of the heat exchanger;
�
Tighten all screws manually
(max. 1.5 Nm);
�
Place all cables in their guiding channels;
�
Place the bottom edge of the front behind the raised edge of the
bottom plate.
This will guarantee an air-tight seal after the screws are tightened.
Install all parts back in reverse order.
