The holding tank drain valve outlet is to be used with a re-
movable termination fitting that locks onto the outlet with a
clockwise twist. Clamp the sewer drain hose to this fitting. A
protective cap should remain in place when you are not drain-
ing the tanks.
To drain the holding tanks:
1. Attach the sewer hose to the holding tank outlet. Insert the
end of the hose into the sewer or dump station inlet, pushing
it firmly far enough into the opening to be secure. In some
cases, adapters may be necessary between the line and the
inlet.
2. Arrange the sewer hose so it slopes evenly.
3. Drain the black water holding tank first. Grasp the handle of
the black water knife valve (the large one) firmly and slide the
valve open with a quick, steady pull.
4. Allow enough time for the tank to drain completely. Rinse and
flush the tank through the toilet.
5. When the tank is empty, push the handle in to close the valve.
6. Run enough water into the tank to cover the bottom. This will
aid the break up of solid wastes.
7. To drain the grey water tank, repeat the steps above using the
small knife valve. This tank is drained last to aid in flushing
the outlets and hose. The grey water knife valve may be left
open in a semi-permanent hookup.
8. Remove the sewer hose and cap the outlet.
9. Rinse out the sewer hose with fresh water and remove the
sewer hose from the dump station.
10. Replace sewer or dump station covers.
