General Safety Instructions

Caution!

This manual must be read and understood before adjustment, maintenance or service is
performed. Modication of this product can 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 dump valves.

2. Do not permit foreign objects (paper towels, paper cups, diapers, sanitary napkins, etc.) to
be ushed through the toilet.

3. Mechanical seal toilets, like Dometic units, 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
“Winterization and Storage” procedures or your warranty coverage may be voided.

Toilet Model Identification

The model identication label is located on
the toilet base under the pedestal cover
and will show the model number and serial
number. Remove base cover to locate
identication label (see page 5).

Operation

To prepare the Dometic toilet for use, check to be sure water supply to the toilet is
connected. Turn on water supply and check system for leaks. Flush toilet and check for leaks.

To properly use the Dometic toilet, follow these simple instructions:

1. To add water to the toilet, lift or raise
the ush pedal until desired water level
is reached. Generally, more water is
required only when ushing solids.

2. To flush toilet, push pedal all the way
down until contents leave toilet bowl.
Water ow pressures vary at different
locations, therefore holding the ush
pedal down for 4-8 seconds may be
required. Minimum ow at the toilet of
two gpm (7.6 lpm) is required for proper
rim and bowl wash.

3. Release ush pedal by allowing it to snap back,
which permits positive sealing around the ush ball.

4. A small amount of water should remain in bowl.

Note
Holding ush pedal down longer than necessary results in excessive water use.

Installation

1. To replace an older toilet, turn off water supply to toilet.
Disconnect water line at toilet water valve. Unscrew oor bolt
nuts and remove toilet. Discard old oor seal and mount­ing bolts. The old oor ange may be used if it is in good
condition and has fastener holes that are positioned correctly.
Make sure center of oor ange is at least 11 inches
(279 mm) from back wall (Figure A).

NOTE: If old oor ange cannot be used and cannot be

removed, please use a SeaLand Universal Mounting Kit,
available from your Dometic dealer.

2. When installing new oor ange, make certain that the toilet
mounting bolts align properly with Dometic toilet mounting
pattern.

3. Secure ange to oor using at head screws through
countersunk holes in ange. Insert oor bolts into slotted
holes in ange (Figure B).

4. If toilet is being installed in a shower stall, apply a 1/4" thick
by 3/4" wide bead of glazing compound around the circum­ference of the oor ange (Figure C).

5. Dometic toilet models 111, 510 and 511 will accept handicap
or household decorative seats. Remove existing seat and
replace with new seat if desired.

6. Position oor seal by pressing the oor bolts up through
holes in the seal.

7. Set toilet in place with bolts protruding up through mounting
holes in base (Figure D).

8. Install washers and hex nuts provided with toilet. Tighten
nuts down equally with standard 7/16" open end wrench.
Remove excess glazing compound from around base in
shower stall installation.

9. Connect water supply line to water valve (1/2" NPT) inlet
using appropriate ttings or an extension (Figure E).

10. Turn on water supply and ush toilet to test for leaks.

11. Attach pedestal and pedal covers to toilet base
(see instructions below).

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.

FLUSH BALL CLEANING: After a period of time, mineral
deposits from hard water may build up on the ush ball or seal,
resulting in a slow water leak. To prevent this, periodically clean
the ush ball and seal.

1. Remove minor debris from the ush ball and seal by slowly pressing and releasing the ush 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. Turn off water supply to toilet. Fully clean the top of the ush ball and under the
seal where it contacts the ush ball.

3. After cleaning underside of seal, apply light downward pressure to top of seal while brushing
around full perimeter of seal.

4. Turn on water supply. Press ush lever to open ush ball, and use brush and water to rinse away
cleanser and loosened deposits.

Winterization and Storage

When a Dometic toilet is stored for long periods of time or may be exposed to temperatures
below freezing, the toilet must be winterized or stored according to one of the following
procedures.

Caution
This toilet is not intended for use when exposed to temperatures below freezing.

Caution
Never use automotive-type antifreeze (ethylene glycol) in freshwater systems.

Note
Use nontoxic antifreeze (propylene glycol) designated for potable water systems.
(See vehicle owner’s manual.)

Storage options

Non-toxic Antifreeze Winterization (recommended method)

1. Pour antifreeze in potable water tank according to instructions from antifreeze
manufacturer.

2. Flush toilet several times until antifreeze has owed completely through toilet. For toilets
with hand sprayer, the hand sprayer must be turned on to assure antifreeze is cycled
through the sprayer.

Drain Water from Toilet

1. Turn off water supply to toilet.

2. Remove water supply line from water valve.

3. Place a small container under water valve inlet to catch draining water.

4. Press ush pedal and allow water to completely drain from water valve and vacuum breaker.

5. Leave water line disconnected until threat of freezing temperature has passed.

4

Note
Never leave vehicle or premises unoccupied for extended periods of time with
municipal water supply or onboard water pump turned on when there is a possibility
of freezing temperature.

Caution
Toilet warranty does not cover freeze damaged water valve that may result from
improper winterization.

Deodorants and Special Tissue

A gravity-discharge toilet system requires the regular addition of a deodorant product to reduce
waste tank malodors and to help break down holding tank contents. Several factors should be
considered in selecting a deodorant product.

Liquid or Granulated. Liquid products work more quickly by readily going into solution. Granu­lated powder formulations require less storage space and are less likely to leak if the package is
inadvertently damaged.

How Much Deodorant and How to Add It. The deodorant is added directly into the toilet bowl,
then ushed into the holding tank. Follow bottle or package instructions. Conditions of extremely
warm weather, longer waste holding time and larger tank capacities may require more deodorant
treatment. To maintain optimum odor control, the holding tank should be cleaned thoroughly at
least once or more each season depending on use.

Why Not Use Household Toilet Paper in Your Toilet. Household tissues often contain
adhesives which bond together the paper bers from which the tissue is made. The adhesives
prevent the tissue from breaking apart, and their use in “ultra-low ow” systems can cause system
clogging. SeaLand tissue is especially designed for use in low water toilet systems.
Its rapid dissolving properties minimize the amount of residual paper in the holding tank and allow
deodorizers to work more ef ciently.

SeaLand and Dometic Brands versus Other Brands. We constantly strive to provide our system
owners with effective products that have minimal environmental impact and good value. Many
deodorant products do not measure up to our standards of performance and value.
