At the end of each traveling season, the Magnum Opus 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.

Your Magnum Opus 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 formu-
lations, 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.  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 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 Magnum Opus 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.  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.
