WINTERIZING
At the end of each traveling season, the Concerto toilet system must be winterized for storage. The following
procedure should be used:
1. Pump out waste holding tank.
2. Thoroughly flush toilet system with fresh water.
3. Drain freshwater tank.
4. Add freshwater antifreeze to freshwater tank.
5. Flush 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.
6. Turn off electrical power.
CAUTION: The use of freshwater antifreeze that contains alcohol will result in damage to your sanitation
system. Only use propylene glycol freshwater antifreeze that does not contain alcohol.
DEODORANTS AND SPECIAL TISSUE
Your Concerto toilet requires the regular addition of a deodorant product to reduce malodors and to help break down
holding tank contents. Several factors should be considered in selecting a deodorant product.
Liquid or Dry: 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 speak-
ing, formaldehyde formulas control odor very effectively at all temperatures and with all degrees of water hardness.
SeaLand
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 hold-
ing 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 ConcertoToilet? 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. 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 efficiently.
SeaLand versus Other Brands: SeaLand constantly strives 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.
