Dismount the four lighting bulbs.
REMOUNTING
Pe rform in the reverse order the dismounting operations, taking into account the following
recommendations: - the flow flaps c ontrol cables are first fixed to the board with the jacket, in axial contact
with the limiting support and then pass the panel button and the similar flow flap on the
corresponding position, then clamp the cable to the unit support; - check if the levers from the climate unit and from the distribution box, have the adequate
strokes t o ensure the close-opening of the flow flaps; - if yes, mount the assembly (6 ) on the central console, the documents compartment and
the aeration grill ;
- if not, set the sleeve l ength of each control cable to the mounting bracket of the climate
unit and the distribution box.
- the maximum moment for the full flow flaps opening is 1,9 Nm.

GENERALITIES
GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. 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 t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning 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 the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

ITIONING UNIT
DISMOUNTING
Make the unit functioning for at least 10 minutes (if the unit permits).
Drain the circuit at the filling 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.
REMOUNTING
P ut special c ompressor oil on the new elements thread and on the gaskets.
AT TENT ION
The new components must be obligatory provided with protection c overs.
Remove t he protection covers, connect the new component on t he free connection,
and tighten it by hand.
Place the component correctly.
Tighten it at couple.
Refill with refrigerant fluid and oil.
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 100ml
- condenser replacement 30 ml
- evaporator replacement 30 ml
- dryer filter replacement 15 ml
- pipe replacement 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.

DRAINING /FILLING THE REFRIGERANT CIRCUIT
DRAINING
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.
FILLING
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 (0,590kg).
Observe the filling instructions prescribed by the equipment producer.
