The compressor is absorbing the vapors coming from the evaporator at low pressure and
temperature, is compressing them and convey the gas at high temperature and pressure. The refrigerant fluid in high pressure and temperature vapor condition is entering in the second
he at exchanger, which by condensation is transmitting the heat to the external environmental.
At the exit from the condenser, the refrigerant fl uid is in liquid condition, at a high pressure and temperature.

THE CONDENSER
The condenser is placed on the cooling radiator, in the front part of the vehicle and is ensuring
the exhaust of the refrigerant heat accumulated at compression.
In order to grant the optimum condenser operation, frequently check if its outside surfaces are
always clean and the air penetration is not stopped. Also, check the condenser pipes in order not
to show deformations. CONDENSER

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

Af ter 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 ground 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.
