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)
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 SeaLands
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 Technology dealer or see the Need Help 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 bro-
ken 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 attempt 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.
Recent Federal legislation has provided grants to private marinas to install dockside pumps especially in coastal
water. It is estimated that over 3500 pump-out stations, in total, will be added due to this legislation.
Sewage from any source should not be discharged directly into our waters. If you are interested in learning more
about this issue, please contact SeaLand Technology at the phone number or address listed on the back page of
this manual. Request Clean Water Notebook, Volumes 1 and 2.
