HANDLING
For your safety, wear protective gloves!
Warning: the unit must be handled with care and stored 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. 4):
Standard model, return air underneath:
l
Remove the two ¼ turn screws on the lower section of the casing (a). Then
swivel the lower section towards you and lift the casing.
Front return air model:
l
Remove two ¼ turn screws and the grille. This gives access to the two ¼ turn
screws in the casing; remove them, then swivel 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 electrics
box.
To refit the casing (fig.4)
- 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
The unit should preferably be lifted by its mounting holes and never by the
condensate pan, the plenums or the collars. (NCH H or NCH U model)
It is possible to carry out the installation using a fork-lift truck, as long as care is taken
not to damage the unit.

MECHANICAL CONNECTION

To protect against injury or damage to the unit or room, the hydraulic
connections must be made by qualified personnel only.
