Climate control unit
DISMOUNTING
Disconnect the battery.
Dismount :
- climate control box protector;
- climate control box gasket
- gas purge vessel;
- engine air filter.
Detach from clips the front wiring from the
central part of the climate control box.
Dismoun t, then:
- attachment screws of the climate con-
trol unit on the climate control box. - attachment screws of the central part
of the climate control box.
Disconnect and release the climate control
unit from the climate control box.
REMOU NT I NG
Perform the dismounting operations in the
reverse order. Tighten t he attachment screws of the c li-
mate control unit on the climate control box, in
the sequence shown in drawing (1,2,3 ).
The required tightening moment of the at-
tachment screws of climate control unit on the
climate control box is of 0,6 daNm. Connector

DISMOUNTIN G
Disconnect the battery.
Dismount :
- dashboard (see chapter 57 “dash-
board”);
- central console;
- electric windows control connectors;
- front pillars coverings;
- driving post cross beam;
- climate control box protector;
- gas purge vessel;
- climate control box gasket;
- engine air filter;
- climate control box central part from
the eight attachment screws;
- attachment screws of the climate c on-
trol unit and release the climate control blower
after disconnecting it.
- RACV attachment screws (1) on the
climate control box.
Clamp t he two hoses from the heating ra-
diator by means of the MOT 453 device.
Disconnect then the fast couplings from the
RACV heating radiator, recovering the c ool-
ing fluid. Dismou nt then:
- acoustic plate ( 2);
- mixing a nd distribution fl aps control
cables attached on RACV. Release RACV (3).
REMOU NT I NG
Perform the dismounting operations in the
reverse order. Fill up the cooling fluid and perform the cool-
ing circuit purging (see chapter 19 “ Filling –
Purging cooling circuit”).
Check :
- good operation of the flaps cables;
- good attachment of t he air ducts.
The require d tightening moment of t he
RACV attachment screws (1) on the climate
control box is of 0,6 daNm.

AIR CONDITIONING
62 - 1
General
The purpose of the air conditioning unit is to produce a decrease of the tempera ture in t he
passengers compartment a nd to obt ain a l ower value tempera ture c ompare d to the e xterna l
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, during the year it is recommended:-the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in the air conditioning circuit, replace the dryer filter tank and drain
the unit; the same is valid also in case the conditioning circuit remains open without protection
covers more than 10 minutes.
IMPORTANT !
During winter, it is recommended the frequent start of the system, in order to prolong
the lifetime of t he compressor and of the whole system.
T he vehicle equipped with an air c onditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of t he refrigerating agent and compressor oil type prescribed
by the manufacturer.
It is absolutely forbidden to perform welding works on the elements of the ai r condition
circ uits.
The fi lling of the air c onditioning system c an be pe rformed only by means of c harging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended piping protection in order to avoid t heir disconnection
by accident.
Avoid the drip of the oil compressor on the painted vehicle carriage body.
For component replacement implying t he circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

AIR COND
ITIONING UNIT
GENERAL METHOD OF O NE ELEMENT REPLACEMENT OF THE AIR CONDITONING UNIT
DISMOUNTIN G
Make the unit functioning for at least 10 minutes (if the unit permits).
Drain the circuit in the charging equipment.
Measure the quantity of recovered refrigerated fluid.
Release the access to the component that is needed to be changed.
Disconnect the connections.
In order to avoid the moisture infiltration, protect with protection covers.
Dismount the component.
REMOU NT I NG
Apply special compressor oil on the new e lements thread and on the gaskets.
AT TENTION !
T he new components must be obligatory provided with protection covers.
Remove the protection covers, connect t he new component on the free connection,
and tighten it by hand.
Place the component correctly.
Tighten it to the required moment.
Refi ll with refrigerant fluid and oil recommended by the manufacturer.
The filling up with oil for different repairs is to be performed as follows: add in the charging
equipment container, the recovered oil quantity, plus an oil quantity, as it follows:
- sudden damaged of one of the unit’s element or leakage...............................100 ml
- condenser re placement ............................................................................... 30 ml
- evaporator replacement............................................................................... 30 ml
- dryer filter replacement................................................................................ 15 ml
- pipe re placement......................................................................................... 10 ml
For compressor dismounting/remounting without replacement add 120 ml.
If there are signs of moisture in the air conditioning circuit, replace the dryer filter tank.
Compressor oil : PAG SP 10 135 cmc
