●
check that, with thermostat open and engine running idle, that average pressure in the water pump outlet pipe is greater than
500 mm water column.
2.11 INSTALLING AN ADDITIONAL HEATING SYSTEM
We recommend using IVECO type heating systems whenever it is necessary to install an additional heating system.
On vehicles where IVECO does not employ these heaters, installation must be done in compliance with the instructions issued by
the equipment Manufacturer (installation of heaters, pipes, electric system, etc.) and in relation to the following indications.
The additional heating system must respect all national standards on the subject (e.g. tests, specific installations for the transport of
hazardous materials, etc.). It must avoid the use of vehicle equipment that requires certified approval whenever such equipment
may cause a negative impact on performance.
In addition, be sure to:
●
care for the proper operation of all other vehicle systems (e.g.: engine cooling system);
●
check that the battery capacity and alternator power are sufficient for increased current draw (see Chapter 5.7 (
➠
Page 36))
and install a protection fuse on the new circuit;
●
connect - for the fuel supply - the supply system to a supplementary tank that is installed along the return pipe of the engine
fuel. Direct connection to the vehicle tank is allowed under the condition that it occurs independently from the engine fuel
supply, and the new circuit must be perfectly airtight;
●
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 any exposed parts that may be dangerous, and adopt suitable guards when necessary.
The system must allow easy access and prompt maintenance.
The Bodybuilder must provide all necessary maintenance instructions.
a) Water heaters
When the original vehicle heating and engine cooling circuits are involved (see Chapter 2.10 (
➠
Page 44)), the following must be
done to ensure good system operation and safety of the original system:
●
carefully define the connection points between the additional and original systems, in agreement with IVECO, if necessary.
The added pipes must be made of brass or other alloy resistant to the corrosive action of coolant, the coupling sleeves must
respect the requirements put forth by the standard IVECO 18-0400;
●
plan for a rational layout of pipes, avoiding bottlenecks and siphoning bends;
●
install venting valves (bleed points) to allow proper system filling;
●
allow complete circuit discharge, also by installing any additional plugs;
●
adopt, when necessary, suitable protections to limit heat loss.
b) Air heaters
As regards these heaters and for direct cab installation, be particularly cautious with the exhausts (to avoid combustion gasses from
being trapped in the vehicle) and correct distribution of hot air (in order to avoid direct flow).
