Choose the best route for the passage of the coolant pipes and prepare the various compartments of the
vehicle.
The pipes must be accurately positioned, avoiding narrow bends, sharp edges or metal sheeting
which might damage them.
The coolant pipes (and the water pipes in the version with heating RTH) come out through the suction vent for
the air inside and the can and must be directed towards the compressor choosing the best path.
WITHOUT heating (see fig. 11):
Cover the suction pipe G12 with the insulation material supplied in the assembly set.
Slot pipes G12 and G10, supplied in the assembly set, inside the vehicle and connect them to the
compressor and to unit RT 120.
Fit the connections (compressor side) to pipes G12 and G10, then to the compressor. The type of
connection depends on the engine of the vehicle to which the roof-mounted unit is fitted.
Fit the connections, supplied in the assembly set, (conditioner side) to pipes G12 and G10, then to unit RT
120.
WITH heating (see fig. 12):

Slot the water pipes, supplied in the heating kit, inside the vehicle and connect them to the engine and to unit
RTH 120.
Fit the connections (compressor side) to pipes G12 and G10, then to the compressor. The type of
connection depends on the engine of the vehicle to which the roof-mounted unit is fitted.
Connect the water pipes to the engine side. The fitter may choose the connection method to use.
Fit the connections, supplied in the assembly set, (conditioner side) to pipes G12 and G10, then to unit RTH
120.
Connect the water pipes to the unit using the method indicated in fig. 12 and 13.
N.B.: As the pipes pass through the suction opening for the air inside the cab, it is even more
important to carefully insulate the delivery and suction compartments (see note 3).
Inside the vehicle, close the air inlet compartment using a suitable panel fitted with a dust filter, which allows

the easy passage of the air and is easy to remove for cleaning and maintenance.

Install the digital central control unit in a position which can be easily reached by the driver (fig. 14).
In the presence of a digital central control unit, it is possible to alter the value of the temperature required,
intervening directly on it.
For information on the operation of the central control unit and the system, please see the central
control unit manual contained in the wiring and controls kit code 80821378.
