AIR CONDITIONING

62 - 1

General

The purpose of the air conditioning unit is to produce a decrease of the temperature in the

passengers compartment and to obtain  a lower value temperature compared to  the external
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 the compressor and of the whole system.
   The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes in painting cabin 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 works on the elements of the air condition
circuits.
   The filling of the air conditioning system can be performed only by means of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended piping protection in order to avoid their disconnection
by accident.
   Avoid the drip of the oil compressor on the painted vehicle carriage body.
   For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.
