Material: – Not required
Equipment: – Crossheaded screwriver
– Soft bristle brush
– Vacuum cleaner
– Ecological solvent
Preliminary procedures / notes
– The conditioner does not require any maintenance activities. Possible traces of
oil are symptom of leakages from the cooling circuit and replacement is
necessary (see card ACO: replacement).
– The amount of dirt inside the conditioner depends on the quality of the insallation
environment air. The schedule in the maintenance plan refers to a typical
condition.
Before removing the conditioner cover, make sure the powers supply
is off and the inside fan is still.
We advise against using compressed air, due to the impossibility to
check the amount of dirt removed, with the risk to direct it towards the
operators face.
Operating procedure

openings.
b. Unscrew the screws securing the conditioner cover.
c. Lift the cover and remove the earth wire connection.
d. Using a brush, remove the dirt while contemporaneously sucking with the
vacuum cleaner to collect the it. Possible persistent dirt may be removed using
an ecological solvent.
