Important “Don’ts”
•
Don't use facial tissue or regular toilet tissue
in the RV toilet. These will not disintegrate
sufficiently and will often cling to the sides of
the holding tank. Toilet tissue made specifi-
cally for use in RV toilets and holding tanks
is available at most RV supply centers.
•
Don’t dispose of sanitary napkins or other
non-dissolving items in the toilet.
•
Don’t put automotive antifreeze or caustic
chemicals, such as laundry bleach or heavy
detergents into the toilet or holding tank.
These products may damage plastic or rubber
parts in the system.
Cleaning the Toilet
The toilet should be cleaned regularly for
maximum sanitation and operating efficiency. If
an odor is apparent from the toilet:
1. Clean the toilet bowl with a mild bathroom
cleaner. Do not allow cleaners to set in the
bowl for long periods of time to avoid dam-
aging the seals. Do not use caustic or abra-
sive cleaners because it may damage the
plastic surfaces.
2. Dump and rinse holding tank.
3. Add odor control chemical in amount speci-
fied after cleaning and every few days during
use.
4. Remove the water line from the base of the
toilet and clean the screen.
5. If the flush valve becomes stiff after
extended use, it may be lubricated with a sil-
icone spray.Turn the water pump off and
operate flush pedal to drain water from the
toilet bowl. Spray silicone lubricant onto
flush valve inside bowl and operate flush
pedal a few times to ensure free operation.
See winterizing instructions at the end of this
section to prepare the toilet for storage in freez-
ing conditions.
WASTE WATER SYSTEM
(HOLDING TANKS)
The drainage system is self-contained and
uses two separate holding tanks to contain the
waste water until it can be dumped at an appro-
priate 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 lav-
atory. See Specifications Section for your model.
Dumping Holding Tanks
1. Remove drain hose from exterior storage
compartment.
2. Remove dust cap from drain and connect
drain hose. Be sure it is firmly attached.
NOTE: The dump valve drain outlet section
swivels downward when necessary to
avoid bends in the drain hose which
could trap solids while dumping. It will
also provide more direct drainage while
using on-site sewer hook-ups.
3. Place the other end of sewer hose into dis-
posal opening.
4. Open the black water 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 water valve as soon as tank is empty.
