Unit installation
• CV1D vertical model
The unit must be attached at the base of the wall.
Position your attachment holes using the lines (fig.3)
and position your pins to level the unit. Position your
Major2 using the four buttonholes at the rear of the unit
(fig.3, pos.21).
It is recommended to use washers for the attachment
of the unit to avoid buttonholes damaging.
The Major2 may be attached by its bottom with its
threaded M6 inserts (fig.3, pos.24).
• CH41D horizontal model
The unit must be attached using screw rods (not
supplied) inserted in the buttonholes. Ensure that the
unit is perfectly level.
The unit must be installed with air return against a wall
and never in the centre of the room.
In case of wall thermostat control, do not expose it
to the sun, behind a door, nor above an apparatus
generating heat, but rather on an interior wall at 150
cm height.
Hydraulic connections
The hydraulic connections of the coils are located on
the left, facing air discharge.
