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.

CHECKING
It is recommended to check the following: -cr acks or breaches of the battery box (case);
- the battery upper part cleanness;
- the plugs condition.
It is required to strictly check the following: -lack of plugs sulfate composite;
- proceed, is necessary to their cleaning and greasing;
- check the correct wiring plugs tightening at the battery plugs. The existence of an imperfect
contact may generate incidents at engine starting or at battery charging, sparks producing risk
being possible to occur, which may cause the battery explosion;
- check the electrolyte level.
For the batteries provided with access plugs, which may be dismounted, proceed as follows:
-r emove the plugs;
- check the electrolyte level in each element;
-i f n ecessary , refill the level, using only distill ed water, till maximum 1.5 cm above the plates.
AT TENT ION
N ever fill up with electrolyte, but only with distilled wat er.
PRECAUTIONS
It is important to know that: -the battery contains sulfuric acid which is a dangerous substance;
- during battery charging, oxygen and hydrogen are produced. The mixture of these two
gases is forming a detonate gas, which may lead to the explosion risk.
1. DANGER = ACID
The sulfuric acid solution is a very aggressive, toxic and corrosive product. This is a ttacking
the skin, the clothes and may lead to the corrosion of most of the metals. Also, it is very important, that, when you handle a battery , to consider the following precautions:
- protect the eyes by using protective glasses;
- wear anti-acid gloves and clothes. PARTICULARITIES

AT TENT ION
In case of acid slashes on body, abundantly wash with water al l affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current. The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
AT TENT ION
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are
shouted off; -during battery charging in a room, using a c harger-rectifier, turn it off be fore
connecting or reconnecting the battery to this one;
-do not place m etallic objects on the battery for not producing a short-circuit
between its plugs;
-never bring closer to a battery, an open flame, a welding lamp or another fire
source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing. The
battery is to be allwith disconnected by first disconnecting the negative plug and then the positive
one. Connection is to be done by performing the disconnecting operations in the reverse order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the ground), and if the plugs are clean and well tightened. Never disconnect the battery when
the engine is running, in order not to damage the voltage regulator, the alternator or some
components of the vehicle checking electronic systems. The alternator, voltage re gulator
disconnecting, a nd the interventions at their connections, are to be performed only when the
engine is stopped (the alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs. BATTERY
