Intended use
When a toilet is flushed on a boat with a holding tank, air is pushed out of the holding tank, through
a vent hose, and out of the boat through a vent fitting . To stop foul-smelling air from coming out of
the vent fitting, install an ECO Vent Filter .
4 Installation
Remove old filter
(if replacing existing vent filter)
1 . Remove vent hose from both ends of old vent filter . If old vent filter was connected to threaded
fittings for 5/8-in ./16 mm or 3/4-in ./19 mm ID hose, those fittings should remain attached to vent
hose .
2 . Remove old filter from bracket and seal ends with adhesive tape .
3 . Discard old filter in appropriate container .
Install filter
NEW INSTALLATION
1 . Select location for vent filter . Avoid areas near excessive heat sources (engine manifolds,
lights, etc .) . Do not install filter below top of holding tank (fig .
1
p . 2) .
2 . Vent filter can be mounted at any angle . Installations near thru-hull vent reduce chance of filter
damage from potential overfilling of tank .
3 . Install mounting bracket (fig .
