DSAF is the heat-e xtracting component
from cockpit and is mounted in the climate
maintenance box. In order t o cool the cockpit, the warm a ir
must be ab sorbed and re di st ri but e d t he
“cooled“ a ir. T he warm air is goi ng over t he
evaporator to, which is transmitting part of the
temperature, this one being gradually reduced. In the same time, the refrigerant fluid which
is passing through the evapora tor piping is
absorbing the heat from the air going over the
evapora t or a nd a t t he same pre ssure , i s
transformed from fluid to vapors. When coming
out from evaporator, the refrigerant fluid is in
vapor condition.

Pressure controller
LOCATION
Pressure controller (1) is located on the high-
pressure pipe, near the dryer reservoir.
FUNCTION
The pre ssure control ler is perm anently
informing UCE (electronic control unit) about
the circuit pressure. Subject to pressure value in the high-
pressure circuit, UCE is commanding:
- circuit break ( by uncoupling the compressor
clutch) when the pre ssure in the c ircuit is
decreasing under 1,96 + /-0,2 bar a nd clutch
coupling when the pressure is over 2,16 +/-
0,2 bar;
- circuit break when the pressure in the circuit
is over 31,4 +/- 2 bar and compressor clutch
coupling when the pressure is decreasing under
25,5 +/- 2 bar;
- engine fan starting on second speed, when
the pressure is over 17,7 +/- 1 bar and engine
fan stopping when the pressure is decreasing
under 13.7 +/- 1 bar.
REPLAC EMEN T

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.

ACCOUSTIC WARNING - ANTI STARTING
82 - 1
This type of anti starting system is based on the key recognition, which has a special constructio n.
It may be separated in two elements which can be identified in the following way: the key head
(position A.) made of plastic, which c an be dismounted and the metal insertion (position B),
which is fixed and ensured by clipping in the key head.
In the key head, there is a coded independent electronic circuit, which is functioning without
battery. When setting the contact on, the anti starting bushing, placed around the starting contact,
is enquiring and catching the coded signal emitted by the key head, then sends it to the Electronic
Control Unit (E.C.U.) decoder. This one is attached on the front left pillar, under the lower casing
of the dashboard and has the function of receiving the code sent from the bushing. If the decoder
recognises the key code then it will send a coded signal to the injection computer, which compares
it with the previous memorised code and will authorise or not the engine starting In case of the system with ra dio frequency remote control (RF) of the doors blocking /
unlocking, the key head has a different construction, having an activation button of the remote
control and a red L ED, which i s lighted i n the moment of bl ocking/unlocking the doors, by
pushing the key button. Inside t he ke y head there i s the coded electroni c c ircuit for the anti
starting system and a printed electronic circuit, supplied by a battery, for the RF remote control
operation of blocking/unlocking the vehicle doors.
The anti starting system is activated after approximate 10 seconds from the breaking of the
contact and is visualised by the blinking of the anti starting indicator placed on the instrument
panel.
AT T E N T I O N !
If the battery is low charged, the tension drop on the starter, at starting, may cause
the activation of the anti starting system and the engine starting is impossible.

The E.C.U. decoder has the following functions :
- deco ding the signal received from the anti starting
bushing; - send ing a code to the injection computer in order to
author ise the engine starting;
- c ontrolling the anti starting indic ator of the instrument
panel;
receiv ing the coded signal from the anti starting bearings,
for the vehicles equipped with RF remote control;
REMA RK :
In case both keys were lost, the code of the key head (8 characters) and the code of the
me tal insertion (4 characters) can be red from the vehicle-purchasing invoice. If also the
invoice was lost, the two mentioned codes can be found out based on the chassis s eries of that
vehicl e, acces sing the database of the DA C IA manufacture r, callin g the “C lient Voice”
department (phone 0248 500 000).
E.C.U. DECODER
General
- commandi ng the blocking/unlocking of the doors, if the vehicle is provided with RF remote
c ontrol keys;
- co mma nding the ceiling delayed light, for vehicles equipped with this system.
Th
e an ti starting bushing is located around the starting contact and is accessible after the
d ismounting the steering wheel’s half-cases. It catches the signal from the key head and then sends
a coded signal to the E.C.U. decoder.
The ve hicles equipped with RF remote control keys for blocking/ unlocking the doors are provided
with another anti starting bushing which transmits to the E.C.U. decoder also the signal received
from the RF remo te control.
Th e recognition of the two types of decoding bushings is performed by means of codes labelled
on their body, as follows : - code 04 2264J - for vehicles without RF remote control;
- code 8200 044257 - for vehicles with RF remote control. ANTI S TARTING BUSHING
