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).

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.

REPLACEMENT AND SETTING
Ne w parts are not coded. Once mounted on vehicle, in order to become under operation,
the memorization of a code it is necessary.
In order to perform this procedure, i t is absolutely necessary that some ve hicle parts are
already coded (with the vehicle code).
Refer to the assignations table:
ATTENTION :if a part is memorizing the code this one is assigned to this specif ic vehicle
and it is impossible that subsequently this c ode is erased or a second code is memorized. The
first time memorized code can not be anymore erased.
ASSIGNATION TAB LE
〈
The key assigned to a vehicle must be new and already programmed on that vehicle.
REMARK : this may be programmed n vehicle but it is not effective (not assigned).
ATTENT ION :
only the ke ys presented when performing this operation are to be under
operation.
