MARINE SANITATION REGULATIONS
IMPORTANT INFORMATION BEFORE OPERATION
1. Fill freshwater tank and add deodorant to holding tank through toilet bowl.
(See System Start-Up Section, page 5.)
2. Make sure all guests understand the operation of the VacuFlush system
and the instruction label is in plain sight and easy for guests to read.
If this label is not included in this manual, please contact the
SeaLand Product Customer Service Department immediately.
3. Remember the vacuum pump starts automatically. Shut off the system before servicing and do not leave
the boat with toilet system breaker on.
4. Never use drain openers, alcohol, solvents, etc. in the system.
5. If the system does not function properly, refer to the Troubleshooting Section of this manual and repair as
necessary. If problem persists, contact your local SeaLand dealer or see the Parts Distributor section of
this manual.
1. To add water to the toilet before
using, raise flush lever until desired
water level is reached. Generally, more
water is required only when flushing
solids.
2. To flush toilet, press flush lever
sharply down to the floor until contents
clear bowl. A sharp popping noise is
normal when the vacuum seal is broken
and flushing action begins. Be sure to
hold lever down for three (3) seconds.
If flush lever is accidentally released
before waste clears bowl, do not at-
tempt to flush toilet again until vacuum
pump stops running. A small amount of
water should remain in the bowl after
flushing.
3. Do not dispose of sanitary napkins
or other non-dissolving items in toilet,
such as facial tissue or paper towels.
These items can cause plugging of the
system. Refer to the Deodorants and
Special Tissue section in this manual
for more information.
All boats with fixed toilets in U.S. waters and in the waters of some other countries are required to be equipped
with an operable marine sanitation device (MSD). The VacuFlush system is a holding tank or Type III system
as defined by the U.S. Coast Guard.
Type III systems are designed to permit operation of the toilet without the direct discharge of untreated waste
after every flush. This means onboard toilet facilities can be used when the boat is near swimmers, beaches
or shellfish beds.
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. The overboard discharge pump is activated by a keyed switch located in the toilet compartment. This
key should be removed at all times except when discharge pump is operating.
Sewage from any source should not be discharged directly into our waters. If you are interested in learning
more about this issue, please contact Dometic at the phone number or address listed on the back page of this
manual. Request Clean Water Notebook, Volumes 1 and 2.
