TOILET OPERATING INSTRUCTIONS
To properly use the Dometic toilet, follow these simple instructions:
- Use biodegradable tissue such as Dometic brand.
- To add water to the toilet before using, lift or raise the flush pedal.
- To flush toilet, push pedal all the way down until sewage leaves the toilet bowl. Water flow pressures vary at different locations and therefore, holding the flush lever down 4-8 seconds may be required. A flow of 2-4 GPM (8-15 Lpm) is recommended for proper rim and bowl wash.
- Allow flush pedal to snap back, which permits positive sealing around the flush ball.
- A small amount of water should remain in the bowl.
Note: Holding the flush 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.
TOILET MAINTENANCE
CLEANINGThe Dometic toilet should be cleaned regularly for maximum sanitation and operational efficiency. 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:
- Clean out system by flushing several gallons of fresh water through with one cup of liquid laundry soap.
- Add odor control deodorant in amount specified 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 flushed 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 efficiency 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 fibers from which the tissue is made. The adhesives prevent the tissue from breaking apart, and their use in “ultra-low flow” 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 efficiently.
- 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.
