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
warning indicator positioned on the front panel 2.
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 = 3.5 litres.
use ONLY oil of the same type (RotEnergy Plus).
CLEANING/rEPLACING THE FILTErING
ELEMENT
(Fig. 7)
Remove the rear panel, unhook the clips and remove the cover
G. Extract the two filtering elements (primary element C) and
(security element D). 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 w detergent gun) from inside towards
the outside:
• check that the air flows correctly by means of the radiator.
