Operating Instructions
Water line:
17. Locate water valve at rear of ush lever.
18. Attach water supply pipe or hose from water system
to inlet tting on back of water valve.
Pedestal cover:
19. Slide back side of pedestal cover around rear of
toilet base and snap in groove. Close front half of
pedestal cover and snap in groove.
To properly use the Dometic toilet, follow these simple
instructions:
1. A good biodegradable tissue such as Dometic® brand
is recommended.
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. We
recommend 2-4 GPM (8-15 Lpm) for proper rim and
bowl wash.
4. Release ush pedal by allowing it 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 neces-
sary results in excessive water usage.
CAUTION: Do not dispose of sanitary napkins or other
non-dissolving items in the toilet.
Maintenance
Flush pedal cover:
20. Put ush pedal cover back in place.
CLEANING
The Dometic toilet should be cleaned regularly for
maximum sanitation and operational efciency.
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 specied for
your holding tank capacity after cleaning and every
few days during use.
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. Remove inlet
waterline.
4. Press flush lever until all water is drained from
toilet.
