TOILET DOES NOT NEED TO BE REMOVED FROM VEHICLE FOR BASIC REPAIRS
(if necessary)
Flush ball seal
– Dometic’s
revolutionary ball seal allows future
replacement of worn or damaged
ball seals without requiring tools or
toilet disassembly. The ball seal can
be changed in just a few minutes
without removing the toilet from the
floor. Detailed replacement instruc-
tions are included with replacement
ball seal kits.
Snap-in water valve cartridge
–
Allows easy replacement of worn
or damaged water valves. In cold
climates, be sure to follow winter-
izing procedure in owner’s manual
to help avoid water valve failure.
Refer to replacement instructions
in new water valve kit prior to
removal or installation of water
valve assembly.
Factory-sealed bowl-to-base
assembly –
Unlike other Dometic
foot-pedal toilets,
the bowl and
base of 300, 310, and 320 series
toilets should not be separated for
any reason
.
Each Dometic toilet is 100% factory-tested to assure a watertight seal in the toilet bowl before it
is shipped.
After installation at the RV or other vehicle factory, the entire toilet and waste tank system is flood-
tested for leaks by filling the system with water to the rim of the toilet bowl. This process requires
holding the flush ball open with a device which may temporarily distort the ball seal from its original
shape and, as a result, cause the seal to leak water into the waste tank during normal use. The ball seal
may need to be reconditioned to its original shape.
IF NEW TOILET DOES NOT HOLD WATER IN BOWL…
Please follow the procedures below before attempting to replace the seal.
1. Hold flush ball in full open position by pressing on
pedal.
2. Using finger, apply moderate downward pressure
around edge of ball seal.
3. Close flush ball.
4. Keeping flush ball closed, pour one quart of
hot tap water into toilet bowl.
5. Let water cool completely.
6. Check for leak.
If leak still persists, flush ball seal should be
replaced. Follow instructions provided with
replacement seal kit.

A : This refers to an element in an illustration. In this example, item A in figure 1.
General safety instructions
The manufacturer will not be held liable for claims for damage resulting from the following:
• Faulty installation or connection
• Damage to the unit from mechanical influences, misuse or abuse
• Alterations to the unit without express written permission from the manufacturer
• Use for purposes other than those described in this manual
Warnings
The following statements must be read and understood before installing, servicing and/or
operating this product. Modification of this product may result in property damage.
1. Do not use chlorine or caustic chemicals, such as laundry bleach or drain-opening types, in
the system. These products damage the seals in toilets and other plumbing valves.
2. Do not permit foreign objects (paper towels, paper cups, diapers, sanitary napkins, etc.) to be
flushed through the toilet.
3. Mechanical seal toilets are designed to only discharge directly into a holding tank. Horizontal
pipe runs as found in conventional residential or commercial plumbing systems cannot be
accommodated.
4. Toilet bowl must be regularly cleaned and winterized according to “Cleaning” and “Winteriza-
tion and storage” procedures in this manual, or your warranty coverage may be voided.
Intended use
Dometic 300, 310 and 320 series toilets provide lightweight, residential-size toilets for installation
directly above a holding tank.
Benefits
PowerFlush technology.
Improved pressurized rim flow creates high-speed vortex of water for full
bowl rinsing.
Premium user comfort.
Full-size seat and deep bowl result in greater homelike performance.
Easy installation.
Two-bolt design fits most existing toilet floor flanges – great for new or replace-
ment installations. Just place on floor flange, tighten bolts, connect water, and it’s ready.
Ergonomically enhanced pedal operation.
Lower pedal height for easier use; “one-direction”
action to add water and flush.

Operation
7.1
Add water to bowl
To add water to the toilet, pr
ess the flush pedal
part way down. Water flows into the bowl while
flush ball remains closed. If the flush ball moves,
let up on the pedal slightly. Adding water to an
empty bowl helps prevent holding tank odors fr
om
entering the living space. Adding water is recom
-
mended prior to flushing solids and toilet paper.
7.2
Flush toilet
To flush, pr
ess pedal down until it contacts the
floor. Release pedal after complete flush.
•
When flushing liquids, press the pedal for 1-2 seconds.
•
When flushing solids, press pedal until contents ar
e rinsed from bowl. Flushing longer than
necessary will cause holding tank to fill too quickly.
A small amount of water will collect in the bowl after a flush to create an airtight seal.

Note
To ensur
e holding tank odors do not enter the living space, make sure 1 inch (24 mm) of
water remains in the toilet bowl. Depending on variations in plumbing systems and user
operation, the “add water” function may be requir
ed to achieve the 1-inch water depth.

Cleaning
8.1
Routine toilet cleaning
For routine cleaning, use SeaLand
®
Toilet Bowl Cleaner
. If this cleaner cannot be found in your area,
contact Dometic for your nearest dealer
. If the cleaner is not available, use most any non-abrasive
bathroom and toilet bowl cleaner
. Please follow label instructions.
For stubborn stains on model 300 and 301 toilet bowls, car
efully use rubbing alcohol to remove them.
8.2
Flush ball/seal cleaning
After a period of time, mineral deposits from har
d water may
build up on the flush ball or seal, resulting in a slow water
leak. To pr
event this, periodically clean the flush ball and seal.
1.
Remove minor debris from the flush ball and seal by
slowly pressing and r
eleasing the flush pedal several
times. This will loosen and rinse debris from the surfaces.
Repeat several times for stubborn buildup.
2.
If step 1 does not fully clean the ball and seal, clean with a soft bristle brush and SeaLand toilet
bowl cleaner. Fully clean the top of the flush ball and under the seal wher
e it contacts the flush
ball. After cleaning underside of seal, apply light downward pr
essure to top of seal while
brushing around full perimeter of seal.
3.
If this does not correct a leaking seal, it may r
equire r
eplacement.
Flush directions ar
e located under
toilet seat lid.
