MARINE SANITATION REGULATIONS
All boats with fixed toilets in U.S. waters and in the
waters of some other countries are required to have an
operable, permanently installed marine sanitation device
(MSD). Series 970 MSD models, when permanently
installed in a boat, are holding tank or Type III systems
as defined by the U.S. Coast Guard. Type III systems
permit operation of the toilet without direct discharge of
untreated waste after every flush. Type III systems can
be discharged at marina dockside pump-out stations or,
if in coastal waters, a minimum of three miles offshore.
Overboard discharge capability must remain secured
while within the three-mile limit. If an overboard
discharge pump is activated by a keyed switch in the
toilet compartment, the key must be removed at all times
except when discharge pump is operating and in the
process of vessel operation.
Sewage from any source should not be discharged
directly into our waters. If you are interested in learning
more about this issue, please visit our website at
www.DometicSanitation.com.

models.

When using the Dometic portable toilet in cold or winter weather, the addition of nontoxic antifreeze
designated for potable water systems provides safe winter protection. Use amounts specified on
container that are safe for use with 4 gallons (15 l) of water.
NOTE: Never use alcohol-based or automotive-type antifreeze in freshwater systems.
Storage
To store Dometic portable toilet during the winter:
1. Empty freshwater tank and holding tank.
2. Make sure all water is cleared from freshwater tank’s water lines by pressurizing tank and
pushing flush button until no water enters bowl.
A small amount of water may remain in bottom of freshwater tank but will be harmless during winter
storage.)
