MAINTENANCE AND SUGGESTIONS FOR USE
Any repairs or operations to top up and recuperate coolant must be carried out by authorised
Autoclima workshops and by qualified personnel.
After the first 1500 Km travelled following installation of the conditioning unit, it is advisable to carry out a
general check, paying particular attention to the tightness of the screws and bolts that hold it in place.
A couple of times a year, check the tension of the compressor drive belt: if it is worn, replace it with another
of the same type.
The correct operation of the conditioning unit depends on regular maintenance.
If the conditioning unit is used in very dusty environments, maintenance must be carried out more frequently.
It is advisable to keep the vehicle doors and windows closed while the conditioning system is running.
Before removing the cover of the roof unit to carry out maintenance and cleaning operations, disconnect the
vehicle battery.
Protect the electrical components while cleaning the system.
If replacement of electrical components is necessary, it is possible to access the unit easily by removing the
outer cover.
Avoid leaving the conditioning unit inactive for long periods of time, activating it for at least half an hour once
a month, even during the winter, as operation guarantees the lubrication of certain components which tend to
dry out if left idle for too long.
Check the condenser battery regularly and, if necessary, clean it using compressed air, taking care not to
damage the aluminium fins.
Insects, fluff and other foreign bodies may be deposited on the fins, leading to a reduction in the effectiveness
of the heat exchangers.
When working near the heat exchangers, pay attention not to cut yourself with the sharp ends of the fins.
At the same time, it is wise to check the operation of the condenser electric fan.
When the AC function is activated, the condenser electric fan starts running at low speed, regardless of
whether or not the compressor has been connected. It is necessary to consider that the max. ventilation speed
of the condenser electric fan starts only after a certain pressure is exceeded in the system following
intervention of the Trinary manostat (HP), so it is entirely normal for the overall running time to increase when
the ambient temperature increases.
Remember that the cleaning of the condenser and the check on the correct ventilation are extremely important
operations. A very dirty or poorly ventilated condenser not only causes a drop in the performance of the
conditioning system, it may also cause a reduction in the life of the compressor or even breakage of the
condenser or its electromagnetic joint.
