Operating principle
The climate control assembly is enabling outside air penetration in the vehicle climate control
unit.
Climate controls:
A – air temperature adjustment
B – air distribution in the cockpit
C – air quantity adjustment in cockpit
Air temperature adjustment
Control knob (A) is enabling the obt aining of t he de sired tempera ture in t he cockpit. By
turning to the right the knob (A), the air temperature is increasing.
Air distribution in the cockpit
Ai r distribution in the cockpit is obtained by means of rotating t he knob (B) in the desired
position.
Position
Airflow is directed towards the dashboard air vents.
Position
Airflow is directed towards all dashboard air vents and passengers l egs.
Position
Airflow is directed towards passengers legs.
Position
Airflow is directed between all a ir vents, front side windows defrosting vents, windscreen
defrosting vent and passenger legs.
Position
Entire airflow is directed towards windscreen and side windows defrosting air vents. For a
more substantial efficiency, close the dashboard air vents.

Operating principle
Air quantity adjustment in c ockpit
The flow of circulating air in cockpit is adjusted by rotating the (C) knob in the correspondin g
positions for the four speed steps of the blower. The more speed step is bigger the more airflow
is bigger.
For a be tter effi ciency of the windscreen defrosting or de fogging, t he (C ) knob m ust be
placed on the last position. In order to complete closing of the cold air penetration, rotate the knob on “ 0” position.
Air conditioning AC
When pushing the (D) button, the starting / stopping of the air conditioning is ensured. If ( D)
button is not pushed, the air conditioning is not working, ventilation being identical to the one of
a vehicle without air conditioning.
The use of air conditioning is enabling:-lowering the a ir temperature i n cockpit when the vehicle i s driven in sunny places or
when the vehicle is stopped in the sunshine; -reducing the humidity in cockpit (event facilitated by defogging).
Air conditioning can not be used at low outside temperatures. During air conditioning operatio n,
for a better efficiency, all windows must be closed.
R ecycled air
When pushing the ( E) button, the climate maintenance unit is working with cockpit recycled
air, without outside air penetration.
Air recycli ng is enabling:
- isolation from outside atmosphere;
-f aster reaching the desired temperature in cockpit.
Prolonged use of this function may lead to glasses fogging. Normal operation returning, with
outside air, is t hen imposed, by pushing the (E) button stopping the cockpit air recycling.

DISMOUNTIN G
Dismount the protector of the climate con-
trol box.
Remove from clips the wiring towards
blower casing from the D.S.A.F. Dismount then the particles filter protec-
tion cap from the attachment screw by slid-
ing it towards front of the vehicle.
Extract the particles filter, by easy folding
it.
R EMOU NT I NG
Remount in i ts place the part icles filter per-
forming the same dismounting operations.

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.
DISMOUNTIN G
Drain the AC unit.
Disconnect the battery.
Dismount :
- climate control protector;
- climate control box gasket;
- expansion vessel;
- engine air filter
Detach the front wiring from attachment clips
on the climate maintenance box closing plate.
Di smount the c limate maintenance box
closing plate. Dismount the nut (1) of the pipes attachme nt
clamp (2) on thermostatic expansion valves (3).
Mount protectors at the dismounted pipes.
Dismount the attachment screws (6 ) of the
thermostatic expansion valve.
Release t he thermostatic expansion valve
and mount protectors.
Extract the sealing gasket (7).
Mount protectors at the evaporator’s pipes (8).

Cold air blowing device (DSAF)
Disconnect the climate maintenance blower
connector ( 11) (pull the red part towards arrow
A).
Di smount the attachment screws of the
steering wheel half-case and release from clips
detaching. Dismount the upper part dashboard and
release it from clips.
Dismount the radio-cassettes player. Disconnec t t he c entra l l ocking swi tch
connector (if the vehicle is provided with central
locking). Dismount the right air vent.
Dismount the DSAF attachment screws on
cowl panel and a ttachment screws on climate
maintenance box and release it.
Di smount the attachment screws ( 9) o f the
connection pipe ( 10) on the distributor of RACV
AC-ventilation air and release it.
REMOU NT I NG
Perform the dismounting operations in the
reverse order, taking into consideration that filter
reservoir is to be mounted the last. Fill the air conditioning unit with refrigerant
fluid HFC 134a (0,600 Kg).

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.
DISMOUNTIN G
Drain the refrigerant c ircuit t o a charging
station.
Disconnect the battery.
Disconnect the supply wiring connector of
the compressor clutch.
Dismount the screw of attachment clamp
of the refrigerant pipes on compressor.
Cover the open piping with protectors.
Dismount the compressor-driving belt.
Dismount the four compressor attachment
screws.
Extract the compressor.
REMOU NT I NG
In case compressor is replaced, this one is
delivered filled with oil. Position the compressor with the filling cap
upwards. Mount the compressor attachment screws.
Tighten the compressor attachment screws
to the required moment of 2,1 daNm.
Remount the two refrigerant pipes and
tighten t he attachment clamp screw to the re-
quired moment of 1,2 daNm.
Mount the compressor -driving belt and ten-
sion it by acting upon the screw ( 1) according
to the method descri bed in chapter 07 “ Ac-
cessories belts tensioning”.
The tensioning values are :
150 - 155 Hz - compressor belt;
214 – 230 Hz – DA pump/compressor belt.
Connect the supply wire connector of the
compressor clutch. Vacuum and fill the circuit with refrigerant
fluid HFC 134a , by means of the charging sta-
tion (see chapter 62 “Draining – Filling unit
refrigerant circuit” ).
REMARK :
Before mounting c heck t he condition
of t he gaskets and lubri cate them wi th
compressor oil PAG SP 10.
