8 - PROPULSION SYSTEM 256
8.8.7 Water/fuel separator lters for generators
Maintenance and water drain from collection tank
Purge frequency or the replacement of the lter element (1) are determined
by the contamination level of the fuel.
Check or drain the water collection tank (2) daily.
The collection tank must be drained before containments reach the engine.
• After having placed a capacious collection container underneath it, open
the drain to discharge containments.
• Remove the cover (3) and ll with clean fuel.
• Close the cover and tighten the T-handle (4) rmly by hand.
Replacement of lter element
Replace the element according to the schedule recommended by the manu-
facturer or if a lack of power is noticed. Power loss indicates that the element
is indeed clogged. Other elements like a too full tank or excessively contami-
nated fuel can also clog the lter.
• Close the seacock.
• Remove the cover.
• Remove the element by holding the handle and by pulling lightly forward
with a twisting movement.
• Insert a new lter having the same ltering features of the one replaced.
• Check and, if necessary, replace the lter cover gasket. Apply a layer of
clean fuel or engine oil on the seal before reinstalling it, insert the new
element with a slow twisting movement downwards.
• Fill with clean fuel, then replace the cover. Tighten the T-handle manually
and reopen the valve.
• Start the engine and ensure there are no leaks. Repair any leaks with
engine shut off.
MAINTENANCE
At least once a month check the operation. At least once a week, and
anyway before each refuelling, check for the presence of water in the fuel.
If necessary drain the water present. When necessary, but at least once
a year, replace the cartridge of the lters.
