SUGGESTIONSNo defect should be present or memorized
The de tonation sensor should generate a signal, the amplitude of which must differ from 0,
a proof of the fact that it perceives the mechanical vibrations of the engine.
If th e signal = 0:
- check if the sensor is well fixed
- ch eck the insulation and continuity of cabling along the circuits:
pin 20 of calculator
♦ pin 1 of detonation sensor
pin 79 of calculator
♦ pin 2 of detonation sensor
pin 19 of calculator
♦ pin 1 of detonation sensor screening.
Replace detonation sensor if necessary.

With the engine hot, in the stage of the idle mode adjustment, watch these parameters and
notice:
- if one of the parameters drifts to the MAX limit, then there is no enough petrol
- if one of the parameters drifts to the MIN limit, then there is too much petrol.

GENERALITIES
GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. During the year it is recommended:
- the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

AIR COND
ITIONING UNIT
DISMOUNTING
Make the unit functioning for at least 10 minutes (if the unit permits).
Drain the circuit at the filling equipment.
Measure the quantity of recovered refrigerated fluid.
Release the access to the component that is needed to be changed.
Disconnect the connections.
In order to avoid the moisture infiltration, protect with protection covers.
Dismount the component.
REMOUNTING
P ut special c ompressor oil on the new elements thread and on the gaskets.
AT TENT ION
The new components must be obligatory provided with protection c overs.
Remove t he protection covers, connect the new component on t he free connection,
and tighten it by hand.
Place the component correctly.
Tighten it at couple.
Refill with refrigerant fluid and oil.
The filling up with oil for different repairs is to be performed as follows: add in the charging
equipment container, the recovered oil quantity, plus an oil quantity, as it follows:
- sudden damaged of one of the unit’s element or leakage 100ml
- condenser replacement 30 ml
- evaporator replacement 30 ml
- dryer filter replacement 15 ml
- pipe replacement 10 ml
For compressor dismounting/remounting without replacement add 120 ml.
If there are signs of moisture in the air conditioning circuit, replace the dryer filter tank.

AIR CONDITIONING
62
62 - 5
Basically, the air conditioning unit is formed of a closed circuit, composed by the following main
elem ents:
- ev aporator
- compre ssor
- c ondenser
- thermo static expansion valve
- conn ection pipes.
The evaporator is the component that ex t racts the heat from the passengers compartment and
is generally placed in the passengers compartment. In order to cool the passengers compartment
the hot air must be absorbed, the heat extracted and the “cooled” air redistributed. The hot air is
pa ssing through the evaporator to who is giving part of the temperature reducing so, its own
temperature. The cooled air is so conveyed in the passengers compartment, progressively reducing
the temperature.
In the same time, the refrigerant fluid which goes into the evaporator, is absorbing the heat, from
ai r pa ssing through the evaporator and at the same temperature, is transforming it from liquid into
va pors. At the evaporator exit, the refrigerant fluid is in vapor condition.
The evaporator is placed in the climate control unit and is protected by cases.
