TOILET OPERATING INSTRUCTIONS

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

1. Use biodegradable tissue such as Dometic brand.

2. To add water to the toilet before using, lift or raise
the ush pedal.

3. To ush toilet, push pedal all the way down until
sewage leaves the toilet bowl. Water ow pressures
vary at different locations and therefore, holding the
ush lever down 4-8 seconds may be required. A ow
of 2-4 GPM (8-15 Lpm) is recommended for proper
rim and bowl wash.

4. Allow ush pedal to snap back, which permits positive
sealing around the ush ball.

5. A small amount of water should remain in the bowl.

Note: Holding the ush pedal down longer than neces­sary results in excessive water usage.

CAUTION: Do not dispose of sanitary napkins or other
non-dissolving items in the toilet.

WINTERIZING

At the end of each season, the Dometic toilet should be
winterized for storage by either draining or using potable
water-safe antifreeze in the system.

To drain:

1. Thoroughly ush system with fresh water.

2. Empty holding tank.

3. Shut off water supply to toilet. Disconnect water line.

4. Press pedal until all water is drained from toilet.

To use antifreeze:

1. Thoroughly ush system with fresh water.

2. Empty holding tank.

3. Drain potable water tank.

4. Add freshwater antifreeze and water mixture
through toilet and into the waste holding tank. Each
installation is different, so amounts may vary. User
discretion is required to assure adequate protection.

5. Empty holding tank.

Note: Use nontoxic antifreeze designated for potable
water systems.

CAUTION: Never use automotive-type antifreeze in
freshwater systems.

PREPARING FOR SUMMER USE

To prepare the Dometic toilet for summer use, turn on
water supply and check system for leaks. Flush toilet,
check for leaks and repair as necessary. Your Dometic
toilet is now ready for use.

TOILET MAINTENANCE

CLEANING

The Dometic toilet should be cleaned regularly for
maximum sanitation and operational efciency.

Clean the toilet bowl with a mild bathroom cleaner,
such as Dometic Toilet Bowl Cleaner. Do not use
chlorine or alcohol-based caustic chemicals such as
drain opening types, as they will damage the seals.

If an odor is apparent from the toilet:

1. Clean out system by ushing several gallons of fresh
water through with one cup of liquid laundry soap.

2. Add odor control deodorant in amount specied for
your holding tank capacity after cleaning and every
few days during use.

DEODORANTS AND SPECIAL TISSUE

Dometic toilets require the regular addition of a deodorant product to reduce holding 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 obviously work more quickly by readily going into solution. Granulated powder
formulations, on the other hand, have the advantage of requiring less storage space and are less likely to leak if the
package is inadvertently damaged.

Formaldehyde versus Non-Formaldehyde: Dometic manufactures both types of deodorants. Generally speaking,
formaldehyde formulas control odor very effectively at all temperatures and with all degrees of water hardness. Dometic
Environment-Friendly brand, which is formaldehyde free, is similarly effective.

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. Also, to maintain optimum efciency in odor control,
the waste holding tank should be cleaned thoroughly at least once or more each season depending on use.

Why Not Use Household Toilet Paper in Your Dometic 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. Dometic 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.

Dometic Brand 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.
