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4 to

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.

For a more pleasant installation day, empty

the holding tank before you begin.

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.

11 Partially Depressing the Flush Pedal

Flush 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

Maintenance

12 Fully Depressing the Flush Pedal

Flush 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.

Residual 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.

If you need to call Dometic for assistance, have

the exact model number available. Refer to

under the seal where it contacts the ﬂush

ball.

Gravity-Flush Toilet

Maintenance

– Aer cleaning the underside of the seal,

apply light, downward pressure to the top

of the seal while brushing around the full

perimeter of the seal.

If the ball pivot arm becomes dislodged

while cleaning inside the base beneath

the ﬂush ball and seal, re-engage it into

the pivot point. Refer to Figure 16 for the

location of the pivot point.

If this procedure does not correct a

leaking seal, it may require replacement.

Detailed replacement instructions are

included with the replacement ﬂush ball

seal kits.

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

15 Identifying a Damaged Water Valve

Freeze Damage

Water 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.

Use 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

This 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.

For toilets with a hand sprayer, the hand

sprayer must be turned on for antifreeze

to cycle through the sprayer.

3. Place a small bucket under the water valve

inlet to catch draining water.

4. Depress the ﬂush pedal and allow water to

completely drain from the water valve and

vacuum breaker.

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

Water Inlet Valve Assembly

In 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.

18 Reconditioning the Flush Ball Seal

Flush Ball Seal

Flush 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

replace the ﬂush ball seal.
