SECTION V MAINTENANCE
Maintenance of the air conditioning system
The system is made up of three units:
Fan-evaporator unit, placed under the cab ceiling;
Power supply unit, consisting of a motor-driven compressor.
Condenser and fan unit mounted on cab roof.
Every 50 hours: inspect radiator-condenser unit. After removing the
protection grating, check if the radiator is dirty or clogged.
Carry out a careful cleaning, if necessary.
N.B. - Should the pipes of the air conditioning circuit come loose, the
system has to be recharged using special equipment. Have the system
recharged by a specialized repair shop.
For further repairs on the heating and conditioning systems consult one of
our Service Centres.
Checking the air conditioning system
(To be performed at the beginning of each working year by a specialized work-
shop)
The presence of air and water in the system could jeopardize its efficiency:
•
the air is uselessly compressed by the compressor and no cooling
effect is produced.
•
the moisture has a tendency to freeze in the coldest parts of the
circuit, thus giving rise to obstructions which prevent the cooling ef-
ficiency.
Also check belt tension: when finger pressure is applied to the mid-point
between both pulleys, the belt should deflect 8-10 mm (0,32-0,39 in) at
most.
The system check begins
by inspecting the condition
of the refrigerant through
the inspection window on
top of the receiver-drier
placed on the cab ceiling.
The refrigerant, as seen
t h r o u g h t h e i n s p e c t i o n
window, should be clear
and free of bubbles.
