Fuel Filter
Aqua-Hot Fuel Filter:
The
fi
lter is located
on the curbside of
motorhome behind the
fuel access door.
Filter Replacement:
Contamination levels in the fuel determine the
frequency of element replacement. Fuel
fl
ow to
the Aqua-Hot becomes restricted as the element
gradually plugs up with contaminates, resulting in
noticeable heating loss and/or hard starting. If this
occurs, change the element as soon as possible.
As a guideline, change the
fi
lter when clogged
(
fi
rst indication of heat loss) or at the beginning of
each heating season. Always carry an extra
fi
lter as
one tank of contaminated fuel can plug a fuel
fi
lter.
Replacement
fi
lters must have a 10-micron rating.
Gar-ber Filter:
Model #R, 10 micron.
To Replace the Filter:
Ensure the Aqua-Hot Diesel switch at the
galley is turned
OFF
.
Spin the
fi
lter counterclockwise and
remove from head. Remove old O-ring
gasket on threaded stud.
Install new O-ring supplied with
fi
lter.
Ensure the gasket is seated in the groove
around the
fi
lter canister.
Apply clean lubricating oil to the new
fi
lter gasket and washer.
Spin
fi
lter onto head until
fi
lter makes
contact then tighten ¾ of a turn.
Start the Aqua-Hot and check the fuel
fi
lter for leaks.
NOTE:
It may be necessary to cycle the diesel
burner switch on and off a few times to
thoroughly purge the fuel system of air.
