4. When the waste water stops flowing, close the termina-
tion valve and open a faucet in the motorhome (either the
bath or kitchen) for a short period to place a gallon or so
of rinse water into the gray waste water tank.
5. Turn off the faucet and open the termination valve to
rinse and empty the gray waste water tank.
6. When rinse water stops flowing, close the termination
valve and stow the sewer hose.
Emptying the Toilet Cassette
The cassette toilet has a built-in level indicator that indicates
when the waste cassette is full and requires emptying. When the
slide turns from green to red, the waste cassette is full.
The toilet cassette is accessed by an external panel located on
the left side of the motorhome (Figure 1).
1. Open the access panel door and press the blue latch to
release the cassette (Figure 2).
2. Pull the cassette out of the cassette bay. Be careful not to
drop the cassette, it may be heavy. NOTE: The cassette has
a sealing mechanism that automatically closes the inlet
when the cassette is removed from the bay (Figure 3).
3. Lower the cassette to the ground, placing it on its built-in
wheels and extend the transport handle (Figure 4).
4. Transport the cassette to a sewage waste disposal site.
5. Rotate the discharge neck, uncap, and while pressing
and holding the vent button with your thumb, empty the
cassette in the sewer inlet.
6. Most sewage disposal sites have rinse water available.
Rinse the cassette with approximately 5 liters of water,
emptying the rinse water into the sewage inlet.
7. Remove the float from the waste cassette and rinse with
clean water. Return the float mechanism to the waste
cassette.
8. If it is desired to continue using the toilet, prepare the
waste cassette for use as previously instructed.
9. Return the cassette to its storage bay. Be sure the carrying
handle is collapsed, the discharge neck is capped and
The Sewage Hose Storage Bay could be damaged
by speed bumps or other road hazards. Always be
conscious of road conditions and the potential of
under-carriage damage to low-mounted devices.

6. Remove the flexible sewer drain hose, and rinse it thorough-
ly with clean water. Remove the other end from the dump
station inlet, and replace it in its storage container.
7. Replace the sewage caps on both the motorhome outlet
and the dump station inlet.
8. Flush the toilet a few times to add a small amount of
water to the black tank. This will help keep any remaining
solids from drying to the tank surfaces.
Emptying the Gray Waste Water Tank; Floor

along the lower left side of the motorhome (Figure 5).
2. Extract the sewage hose and place the end of the hose into
the sewage disposal inlet (Figure 6).
