CHASSIS MODIFICATIONS 2-53 E UROCARGO Euro 4/5 Installing an air---conditioning system 2.12 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 this procedure is not applicable, the installation must be carried out in accordance 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; - check the electrical system to ensure that the battery capacity and alternator output is sufficient for the higher current require- ments (see point 5.8.3). Provide the new circuitry with a protection fuse; - in liaison with IVECO, establish a method for installing the compressor; if it is fitted to the engine, use the 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 complete installation should be designed to ensure good accessibility 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: a) Equipment installed inside the cab - The condenser should not impair the original engine cooling system operation (reduction in the radiating area of the engine radiator). - The best arrangement is to use a condenser, suitably ventilated.
- The arrangement of the evaporator-blower unit in the cab (if not planned by IVECO) should be designed to make sure that the accessibility control and operating equipment is not impaired. b) Equipment fitted on the cab roof - When the equipment (condenser, evaporator, blower) is fitted on the cab roof, make sure that its weight is not higher than that permitted for roof installation. Furthermore, the bodybuilder must provide proper reinforcement to the roof frame if necessary, in relation to the weight 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.
