appropriate waste water disposal site. This means
you can use the toilet, sinks and shower even in
areas where utility hookups are not available.
The black water holding tank contains the
sewage from the toilet and may include bathroom
lavatory on some models. The gray water holding
tank contains the waste water from the galley
sink and shower, and may include bathroom
lavatory.
See "Specifications" in Section 1 -
Introduction for tank capacities for your model.

Dumping Holding Tanks

1. Remove sewer hose from water service
center.
2. Remove dust cap from drain outlet and
connect sewer hose. Be sure it is firmly
attached.
NOTE: The drain outlet swivels downward when
necessary to avoid bends in the drain
hose which could trap solids while
dumping or to provide more direct
drainage while using on-site sewer hook-
ups.
3. Place the outlet end of sewer hose into
disposal opening.

positions may be reversed depending on
floorplan and tank location.
4. Open the Black Waste Tank Drain valve with
a quick pull and make sure there are no sags in
the hose. Move the hose gently about to
dislodge any waste and ensure complete
drainage. Close Black Waste Tank Drain
valve as soon as tank is empty.
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain valve until the black tank is
drained and Black Waste Tank Drain
valve is closed to avoid sewage back-up
into gray tank. Gray water also rinses
any black water solids from the drain
hose.
5. Open the Gray Waste Tank Drain valve. Be
sure there are no sags in the hose to ensure
complete drainage. Close Gray Waste Tank
Drain valve as soon as tank is empty.
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV supply
centers.
7. Rinse sewer hose thoroughly with water and
stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Flushing your Black Water Holding
Tank
The black water holding tank is equipped with
an internal spray head that allows you to rinse the
inside of the tank with a shower of clean water
after dumping.
1. Dump your black water holding tank in the
usual manner at approved sewage disposal
station.
2. Leave Black Waste Tank Drain valve open
while flushing tank.
