2.6 Installation Requirements
This manual will help you replace an existing
toilet. To create a new location for your new
toilet, contact a qualified service professional.
Verify that your existing toilet:
• Has a flexible water supply line coming
through the floor or wall. If the line comes out
of the floor, you will need an elbow adapter
kit.
• Is attached to the floor with two bolts that are
perpendicular to the back wall.
– If there are four bolts, you will need a
Universal Mounting Kit, in the appropriate
color.
– If you are changing the toilet orientation
(the angle of the toilet to the room ), you
can use a Universal Mounting Kit, or
remove the floor flange and install a new
one in your preferred orientation.
• Is level with the floor. If the flange is installed
in the sub-floor, you may need a taller seal
than the one provided.
Make sure there is enough space for your new
toilet. Compare the dimensions for your model
listed in “Toilet Dimensions” on page4to
the measurements listed in “Minimum Space
Requirements” on page5. Verify:
• The rough-in size (from the centerline of the
flange to the back wall)
• The door swing clearance
• That the foot pedal, when depressed, will
touch the same flat surface on which the
toilet is installed.
IFor a more pleasant installation day, empty
the holding tank before you begin.

Operation
IBe sure the entire outlet drain of the toilet
base fits inside the floor flange outlet hole
to avoid leaks.
IThe toilet base might not rest evenly
against the floor yet. The floor flange
seal(FF) will compress as you complete
the following steps.
5. Place the new floor mounting washers (DD)
and then the new floor mounting nuts (CC)
onto the floor mounting T-bolts (EE).
6. Tighten the floor mounting nuts (CC). If a
torque wrench is available, tighten them
to 30–40 in. lb (3.4–4.5 N·m). Do not
overtighten. Alternate between sides when
tightening to prevent distortion. When the
floor-mounting nuts (CC) are tight, the base
of the toilet (AA) should be securely attached
and flat against the floor.
7. Attach the floor mounting caps (BB) onto the
floor mounting nuts (CC).
IIf the toilet (AA) is being installed in a
shower stall (or other wet area), apply a
bead of caulk around the base of the toilet
to prevent water seepage under the base.
8. Connect the water supply line and torque
the connection to 30–40 in. lb
(3.4–4.5 N·m). Do not overtighten.
IIf the water supply line comes out of
the floor, install a 1/2in. (13 mm) elbow
fitting or adapter.
9. Turn on the water supply.
10. Flush the toilet several times and check
for leaks. Refer to “Flushing the Toilet” on
page9.
11. Test for leaks by filling the bowl with water
and letting it sit for an hour.
4 Operation
This section provides instructions on the proper
use of these gravity-flush toilets.
4.1 Adding Water to the Bowl
Adding water to an empty bowl helps prevent
holding tank odors from entering the living
space. Adding water is recommended prior to
flushing solids and toilet paper.
q
11 Partially Depressing the Flush Pedal
qFlush Pedal
1. To add water to the toilet, depress the flush
pedal part way. Water flows into the bowl
while the flush ball remains closed.
2. If the flush ball moves, let up on the pedal
slightly.
4.2 Flushing the Toilet
NOTICE: Flush only water, bodily wastes,
and rapid-dissolving toilet tissue. Do not flush
foreign objects. Do not flush wet wipes, sanitary
napkins, diapers, paper cups, cotton swabs,
food, hair, or liquids such as oils or solvents.
Failure to follow these instructions could cause
clogging or damage to the toilet or the toilet
system.
Gravity-Flush Toilet

10 EN
Maintenance
q
12 Fully Depressing the Flush Pedal
qFlush Pedal
1. To flush, depress the pedal until it contacts
the floor.
2. Release the pedal aer a complete flush.
• When flushing liquids, depress the pedal for
approximately 1–2 seconds.
• When flushing solids, depress the pedal
until the contents of the bowl rinses from the
bowl. Flushing longer than necessary will
cause the holding tank to fill too quickly.
A small amount of water will collect in the bowl
aer a flush to create an airtight seal.
IResidual water trickle in the ceramic
bowls: Due to the integrated rim of the
models 310, 311, 320, and 321 toilets,
water may continue to trickle into the
toilet bowl for up to 20 minutes aer
flushing. If the water trickle continues
aer 30 minutes, replace the water valve.
Refer to “Replacing the Water Valve” on
page14.
So that holding tank odors do not enter the
living space, make sure 1 in. (24 mm) of water
remains in the toilet bowl. Depending on the
plumbing system and user operation, adding
water may be required to achieve this water
depth. Refer to “Adding Water to the Bowl” on
page9.
5 Maintenance
Properly cleaning, winterizing, and maintaining
your toilet will increase its lifespan.
NOTICE: If this toilet ever requires service,
read the following statements before servicing
the product. Failure to follow these guidelines
can cause product damage and can void your
warranty coverage:
• Do not separate the ceramic bowl from the
plastic base. Unlike other Dometic foot-
pedal toilets, the bowl and base of the 300,
310, and 320 series toilets should not be
separated for any reason.
• Do not remove the foot pedal from the base.
This toilet has a factory-sealed bowl-to-base
assembly.
• Do not disassemble the components.
• Refer to this manual and replacement kit
instructions for maintenance and service
information.
The toilet does not need to be removed from
the vehicle (or unfastened from the floor) for
basic repairs, like the flush ball seal replacement
and water valve replacement.

5.5 Winterizing and Storing the
Toilet
WARNING: POISON HAZARD.
Do not use automotive-type antifreeze
(ethylene glycol) in freshwater systems.
Failure to obey this warning could result
in death or serious injury:
CAUTION: BODILY HARM HAZARD.
This toilet is not intended for use when
exposed to temperatures below freezing.
Failure to obey this caution could result in
minor or moderate injury.
NOTICE: The toilet warranty expressly excludes
coverage for any damages to the toilet or
the vehicle that may occur due to improper
winterization of the toilet. Freeze damage that
results in leaks to the water valve is an indicator
of improper winterization.
5.5.1 Preventing a Frozen Water
Valve
q
w
15 Identifying a Damaged Water Valve
qFreeze Damage wWater Valve Damage
These toilet water valves exceed the applicable
standards for maximum water pressure as
defined by the North American plumbing code
agencies. However, if trapped water freezes in
the piping that supplies water to the toilet, it
expands and creates extremely high pressure
that can damage the valve.
If the freeze damage indicator window (1) has
white stress marks, it indicates freeze-damage.
Water valve damage is due to severe exposure
to below-freezing temperatures.
To avoid damage, winterize the toilet as
described in this manual. If freeze damage
occurs as a result of improper winterization,
replace the water valve with a 300/310/320
series toilet water valve kit.
If the water valve is returned for a warranty claim,
Dometic reserves the right to deny the claim if
the problem is caused by freeze damage.
IUse nontoxic antifreeze (propylene
glycol) designated for potable water
systems (See the vehicle owner’s manual).
When a toilet may be exposed to temperatures
below freezing, the toilet must be winterized
using the “Non-toxic Antifreeze Winterization
Method” on page12 or the “Drain Water
from the Toilet Method” on page13. When
a toilet is stored for long periods of time, or the
water becomes stagnant, flush the system using
the “Drain Water from the Toilet Method” on
page13.
5.5.2 Non-toxic Antifreeze
Winterization Method
IThis is the recommended method.
1. Pour non-toxic antifreeze into the potable
water tank according to the instructions from
the antifreeze manufacturer.
2. Flush the toilet (several times) until the
antifreeze has flowed completely through
the toilet.
IFor toilets with a hand sprayer, the hand
sprayer must be turned on for antifreeze
to cycle through the sprayer.

5. Leave the water line disconnected until the
threat of freezing temperatures is past.
NOTICE: Do not leave the RV unoccupied for
extended periods of time with a municipal water
supply connected, or with the onboard water
pump turned on, when there is a possibility of
freezing temperatures.
5.6 Replacing the Water Valve
Refer to the detailed replacement instructions in
the water valve replacement kit before removing
or installing a water valve assembly.

17 Removing the Water Valve Assembly
qWater Inlet Valve Assembly
IIn cold climates, be sure to follow the
winterizing procedure in this manual to
help avoid water valve failure.
5.7 Reconditioning the Flush Ball
Seal
Each toilet is factory-tested to assure a watertight
seal in the toilet bowl. This quality-assurance
testing process requires a device to hold the
flush ball open, which may temporarily distort
the flush ball seal from its original shape. As a
result, it may cause the flush ball seal to leak
water into the holding tank during normal use.
If you discover a water leak into the holding tank,
recondition the flush ball seal into its original
shape.

q
18 Reconditioning the Flush Ball Seal
qFlush Ball Seal wFlush Pedal
1. Depress the pedal to hold the flush ball
open, then lightly press down around the
edge of the seal with a finger to conform the
seal to the flush ball.
2. Release the pedal.
3. Keeping the flush ball closed, pour 1 qt
(0.9L) of hot tap water into the toilet bowl.
4. Let the water cool completely.
If the toilet does not hold water in the bowl, refer
to “Troubleshooting” on page15 before you
