DRAIN CONDENSATE (Fig. 6)
The oil/air mixture cooling is set at a higher temperature with
respect to the dew point of the air (under standard operating
conditions of the compressor). However, the condensate in the
oil cannot be fully removed.
Blow off compressed air through cock B and then close it as
soon as oil begins to flow out instead of water. Check the oil
level and top up if necessary.
CONDENSATE IS A POLLUTING MIXTURE! It must not be
let into the sewage.
OIL CHECK AND TOP UP IF NECESSARY (Fig. 6)
With the compressor off, check the oil level by means of the
oil level indicator positioned on the tank.
If the level is under the minimum, remove the front panel and
refill through hole A. Quantity of oil for refilling from the min to
the max level, see the technical data table.
Use ONLY oil of the same type (FSN Original Oil).
CLEANING/REPLACING THE FILTERING
ELEMENT (Fig. 7)
Remove the rear panel, unhook the clips and remove the cover
D. Extract the two filtering elements (primary element D1) and
(security element D2). Clean them using compressed air, acting
from the inside towards the outside.
Control, against the light, for the presence of splits: in this case
replace filters.
The filtering elements and the cover must be assembled
carefully, so as not to allow the passage of dust into the
compressor unit.
Never allow the compressor to function without the
filtering element.
CLEANING THE RADIATOR
It is recommended that in case of over temperature anomalies
and however, at least once a year that the radiator is
cleaned.
Proceed as follows:
• position a sheet of protective plastic under the radiant
pack;
spray (with a washing + detergent gun) from inside towards
the outside:
• check that the air flows correctly by means of the radiator.
REPLACING THE OIL FILTER (Fig. 8)
With the compressor stopped, remove the front panel.
This operation must be carried out with the tank not pressurised.
Alarm signal.
At each change replace also the oil filter E, unscrew the old
filter and replace it. Always apply some oil on the edge of the
filter and on the seal before refitting manually the filter.
REPLACING THE SEPARATOR FILTER (Fig. 8)
Bleed all air.
•Loosen all hose connections positioned on oil separator
upper flange.
•Remove flange F1 fastening bolts F and lift the oil separator
flange + filter unit using adequate lifting equipment.
•Replace oil separator filter G and gaskets G1 and G2.
•Re-insert the components in the tank paying attention to
correct positioning of the gaskets G1 - G2.
•Tighten bolts in a cross sequence. Be sure to tighten bolts
evenly and re-connect all connections.
