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.

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).

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).

Di smount it from screws (6) and release the
cold air-blowing device (2) from the climate con-
trol box (see D.S.A.F. dismounting-remounting)
Di sconnect and release t he two attachment
screws ( 3) of the air blower.
Dismount the resistance’s assembly (7)

recycling control flap in vertical position.
Dismount the attachment screw (1) of the air
filter protection cap (9) and release the filter (8).
Di smount the attachment scre ws (4) of the
D.S .A.F. cases and release the e vaporator ( 5).
REMOU NT I NG
Perform the dismounting operations in the
reverse order. Vacuum then charge the air conditioning
circuit with refrigerant fluid HFc 134a by
means of the charging station.
Check the good oper ation of t he air
conditioning system.
