2.12.2 Installing an Air-Conditioning System
When the installation of an air conditioning system is deemed necessary, it is advisable to use the types recommended by IVECO.
If th is procedure is not applicable, the installation must be carried ou t in ac cordance with the supplier’s instructions and the following
points:
- the installation must not interfere with the correct operation of the vehicle components and of equipment which may be con-
nected with the installation;
- c heck the electrical system to ensure that the battery capacity and alternator output is sufficient for the higher current require-
ments (see poin t 2.16.3). Provide the new circ uitry with a protection fuse;
- in liaison with IVECO, establish a method for installing the co mpressor; if it is fitted to the engine, use th e original IVECO com-
pressor;
- trace pipe and cable paths, the location of brackets and hoses bearing in mind that the overall dimensions and heat affect the
various units on the chassis.
Avoid runs and arrangements that could lead to hazards when the vehicle is running. Use shields or armouring if necessary;
- the c o mplete installation should be designed to ensure good acc essibility for quick and easy servicing. At vehicle delivery, the
bodybuilder will supply all service and maintenance instructions which are deemed necessary.
Furthermore, according to the system operations:
Equipment installed inside the cab
- The condenser should not impair the original engine cooling system features (reduction in the radiating area of the engine radi-
ator).
- The best arrangement is for the condenser not to be combined with the engine radiator but in a separate compartment, suitably
ventilated.
- The arrangement of the evaporator-blower unit in the cab (if not anticipated by IVECO) should be designed to make sure that
the accessibility control and operating equipment is not impaired.
Equipment fitted on the cab roof
- When the equipment (condenser, evaporator, blower) is fitted on the cab roof, make sure that its mass is not higher than that
permitted for roof installation. Furthermore, the bodybuilder should provide for proper reinforcement to the roof frame if necess-
ary, in relation to the mass of the unit and the extent of the modification introduced.
- For specific applications with compressors not supplied by IVECO (e.g. fridge box), contact the IVECO offices in charge.
