2.12.2 Installing an air conditioning system
We recommend using original IVECO units for the installation of an air conditioning system.
When this is not possible, aside from complying with the specific requirements provided by the manufacturer of the equipment, it
is necessary to:
● maintain good performance of the vehicle parts that may be involved in the intervention;
● check that the battery capacity and alternator power are sufficient for increased current draw (see Chapter 5.4 - Paragraph
"Additional equipment" ) and install a protection fuse on the new circuit;
● plan the compressor installation modes with IVECO, if installed on the engine;
● route piping and wiring layout (and installation of brackets and flexible fittings) in relation to the spaces available and the influ-
ence of heat on the chassis parts;
● avoid layouts and installations where exposure may be dangerous when the vehicle is moving; fit suitable guards when neces-
sary;
● the system must allow easy access and ensure prompt maintenance.
The Bodybuilder must provide all necessary maintenance instructions upon vehicle delivery.
In addition, in function of the type of system:
a) cab installed system:
● condenser installation must not cause negative effects on the engine cooling characteristics (reduction of exposed radiator-
engine area);
● the condenser must not be installed together with the engine radiator but in a specific and suitably ventilated bay, unless a
condenser is used that is equivalent (in shape and performance) to the standard model envisaged by IVECO;
● installation of the evaporator unit and of the bellow inside the cab (in cases where not provided directly from IVECO) must
be planned as not to negatively impact control functions and access to equipment;
b) cab roof-installed systems:
● it is necessary to verify that the mass of the equipment does not exceed the weight allowed by the cab; in addition, the Body-
builder must define the structural reinforcements to apply to the cab roof in relation to the unit's weight and type of interven-
tion performed;
● contact IVECO or specific applications that involve an unoriginal compressor (e.g. fridge).
▶ Note that for vehicles of category M1 and N1 class 1, in accordance with Directive 2006/40/EC
on the emissions of air conditioning systems for motor vehicles, the use of fluorinated GHG with
overall heating potential exceeding 150 in relation to CO2 is prohibited.
Note
a) If an additional climate control system is to be connected to the original system of the vehicle, the new total quantity of fluor-
inated greenhouse gases contained in the system (expressed in weight and in CO
2
equivalent) must be indicated by a data plate
which replaces the original data plate.
b) if an additional independent system is to be added, the specific data plate indicating the fluorinated greenhouse gases must be
positioned in line with the access points for the recharging operations.
In both cases, the data plate must be made according to the indications provided in Regulations 517/2014 (EU) and 2015/2068
(EU) in force in the European Union.
