Draining – filling the refrigerant circuit
DRA I NING
Connect the charging equipment piping to the filling-draining valves.
Perform the vacuuming of the air condition unit with the recovering of the oil and the refriger-
ant fluid. Close the hoses valves.
Disconnect the charging equipment piping and stop the equipment.
FILLIN G
Attach the draining – filling hoses of the equipment to the air conditioning unit valves.
Put compressor specific oil t ype SP 10 in the charging equipment vessel.
Set the quantity of the refrigerant fluid that must be charged (0,6 Kg).
Observe the filling instructions prescribed by the equipment producer.

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.

Particles filter
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.
REMARK :
Pay attention at the m ounting direction
of the fi lter the two arrows (A) must be
lined up.

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).
