Compressor
FUN CTION
The compressor is suction the vapors com-
ing from evaporator at low temperature and
pressure, compress them and transmit the gas
at high temperature and pressure towards con-
denser. The refrigerant fluid in entering in condenser
in vapors condition, at high temperature and
pressure, where, by condensing, is transmittin g
in the external environment the abstracted heat.
At condenser exit, the refrigerant fluid is in
liquid condition, at high pressure and tempera-
ture.

pressure at the evaporator entrance, to a default
value. In this way, the fluid passing through the
evaporator may be suction by the compressor
in a complete gaseous condition.

CHECKING
It is recommended to check the following: -cr acks or breaches of the ba ttery box (c ase)
- battery upper part cleanness
- plugs condition
It is required to strictly check the following:
-lack of plugs sulfate composite
- proceed, is necessary to their cleaning and then greasing with neutral grease;
- correct wiring plugs tightening at the battery plugs. The existence of an imperfect contact
may generate i ncidents at engine starting or a t battery charging, sparks producing risk being
possible to occur, which may cause the battery explosion;
- check the electrolyte level;
- check that a eration holes of the access plugs are not closed.
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 necessary, refill the level, using only distilled water, till maximum 1.5 cm above the
plates;
-check that a eration holes of the access plugs are not closed
ATTENTION !
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 chargi ng, oxygen a nd hydrogen are produc ed, so c heck t hat aera tion
holes of the access plugs are not closed 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.

ATTENTION !
In case of acid splashes on body, abundantly wash with water all 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.
ATTENTION !
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 charger-rectifier, turn it off before connecting or
reconnecting the battery to this one;
- do not place metallic objects on t he ba ttery for not producing a short-c ircuit between i ts
pl ugs ;
- never bring closer to a battery, a n 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 t he
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 mass), 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 regulator disconnecting, and
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.

DISMOUNTING
After identification and elimination of the real cause of the battery discharging, proceed as
follows: Remove the plastic protector from the plus plug of the battery.
Dismount the attachment nut of the mass wiring from the minus plug of the battery.
Dismount the attachment nut of the wiring from the plus plug of the battery.
Dismount the battery attachment clamp screw.
Carefully take off the battery.
R EMOU NT I NG
Perform the dismounting operations in the reverse order. After that, reset the radio by intro-
ducing the radio code (if the vehicle is equipped with radio) and adjust the dashboard clock.
