HANDLING
For your safety, wear protective gloves!
Important: The unit must be handled with care and preferably laid flat. Impacts may cause
damage to the frame or the body of the unit and adversely affect its main functions and its
appearance.
REMOVING AND REFITTING THE CASING
When installing the unit, the casing must be removed and replaced in its original packaging, to
protect it from any risk of scratching.
The protective electrostatic casing film must always be removed before the casing is
finally repositioned.
To remove the casing (fig. 3):
●
Standard model, air recovery underneath:
Undo the 2 x ¼ turn screws in the lower section of the casing (a) . Turn the
lower section towards you and lift the casing.
●
Model with front air recovery:
Remove the grille by taking out the 2 x ¼ turn screws. This allows access to the
2 x ¼ turn screws in the casing. Remove these, then turn the lower section towards
you and lift the casing.
Note: If the unit is equipped with a control with flush-mounted terminal, remember to
disconnect the quick-release connector, accessible on the side on top of the electrical box.
To refit the casing (fig.3)
- Position the casing so that it leans at an angle (lower part towards you) making sure that the
central lug (B) is correctly centred.
- Adjust the rear lugs on the rear panel of the frame (A).
- Return the casing to an upright position so that the brackets on the frame clip into the feet on
the casing (C).
INSTALLING THE UNIT
Horizontal model:
The unit should be lifted by its mounting holes. It is possible to carry out the installation using
a fork-lift truck, as long as care is taken not to damage the unit.
The unit is placed inside the false ceiling (NCH model). The unit must be fixed to the ceiling
using 4 threaded rods (not supplied), to be attached to the 4 oblong holes using the resilient
mounts (accessory).
Warning: Do not fit the metal washer.
