Before beginning installation, check that the section of the roof on which you are going to fit the air
conditioning unit has a curve which is compatible with that of the unit.
Ensure that the roof surface corresponding to the conditioning unit supporting area is sufficiently solid.
Reinforce the framework if necessary by adding crossbars to offer further support.
This will prevent sagging in the area where the group is installed and consequent accumulation of water,
which could leak into the vehicle.
Position the conditioning unit centrally in relation to the longitudinal axis of the roof.
Before lifting the conditioner onto the roof of the vehicle, remove the external cover by loosening the relative
1
fastening screws (fig. 07).
To fit the air conditioning unit, it is necessary to make 5 openings on the roof of the vehicle (4 for the delivery
2
of the treated air and 1 for the internal air inlet) + 8 holes for the fastening points (see fig. 04).
Before cutting the bodywork, disconnect the vehicle battery; check that no electric wiring passes
through the section of the roof where you intend to make the openings.
Make the openings in the spaces between the roof ribbing elements, without removing them.

04
After making the openings, check that the compartments that run through the cavity in the roof for the
delivery of the conditioned air and the inner air aspiration (corresponding to the openings made) are
3
completely separate.
If this is not the case, carefully seal the compartments (see fig. 05).
Glue the stretches of gasket G on the roof of the vehicle, following the instructions of fig. 06, 07.
4
Then apply a suitable sealing product onto the upper surface of the seals that are going to come into contact
with the bottom of the conditioner and around the fastening holes made (fig. 06, 07).
Position the conditioning unit in such a way that the delivery compartments and the suction compartment
5
correspond exactly to the openings made in the vehicle roof. Fasten it to the roof using M.8 screws (not
supplied) (fig. 05, 07).
Connect the condensation discharge tubes B in pairs to the 4 fittings beneath the unit (see fig. 08, 09, 10).
6
It is extremely important that there are no siphons or choking along the hole length of the waster
drainage pipe and that it always slopes downwards.
