the product.
WARNINGS
Dometic vacuum toilet systems must be installed
according to Dometic’s recommended procedures.
Dometic also recommends that a qualied marine
technician or electrician install or service this product.
Equipment damage, injury to personnel or death
could result from improper installation. DOMETIC
SANITATION CORPORATION ACCEPTS NO
RESPONSIBILITY OR LIABILITY FOR DAMAGE TO
EQUIPMENT, OR INJURY OR DEATH TO PERSONNEL
THAT MAY RESULT FROM IMPROPER INSTALLATION,
SERVICE OR OPERATION OF THIS PRODUCT.
WARNING!
HAZARD OF FLOODING – If the toilet
system is connected to ANY through-the-hull ttings,
properly installed seacocks MUST be installed in all
piping connected to through-the-hull ttings. Seacocks
MUST be easily accessible to all users of the toilet
system or secondary valves tted in hoses where they
are easily accessible. ALWAYS close seacocks when
toilet system is not in use (even if boat is unattended
for a brief period. All valves MUST be full bore valves
and marine quality. Screw-to-close gate valves are not
recommended. Failure to comply can result in ooding
which can cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet is
connected to ANY through-the-hull ttings, ALL
exible hoses must be of marine sanitation quality
and must be secured to ANY ttings (such as those at
seacock, vented loop or toilet) with two stainless steel,
worm-drive hose band clamps at each connection.
Connections MUST be checked frequently for integrity.
Failure to comply can result in ooding which can
cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet rim is
below the waterline at ANY time (during any conditions
of heel, load or trim) and is connected to ANY throughthe-hull ttings, properly positioned ventilated (vented)
loops MUST be installed in intake* or discharge piping
to prevent potential back siphonage of seawater into
the boat. Failure to do so can result in ooding which
can cause loss of property and life.
* if connected to raw water
HAZARD OF FLOODING – If the toilet
uses fresh water for ushing and is connected
directly or indirectly to a shoreside municipal water
system at ANY time, shoreside water connections
MUST be disconnected if the boat is unattended (even
for a brief period). Failure to comply can result in
ooding which can cause loss of property and life.
HAZARD OF FLOODING – If toilet uses
raw water for ushing at ANY time, a raw water pump
controlled by an automatically operating demand
switch MUST NOT be installed. If the onboard water
valve or any plumbing connections were to leak, the
automatically operated pump would start and could
ood the boat. Failure to comply can cause loss of
property and life.
HAZARD OF FLOODING – Before
beginning any work on this product, be sure that all
electrical power to the unit has been turned off. Failure
to do so can result in ooding which can cause loss of
property and life.
HAZARD OF SHOCK OR FIRE –
Always use recommended fuse, circuit breaker and
wire size. Failure to do so can result in re that can
cause the loss of property and life.
CAUTION:
can create serious damage to the sanitation system,
such as rupturing the holding tank and releasing tank
contents into the bilge. To prevent this possibility,
Dometic strongly recommends the addition of a “full”
tank safety shut-down relay to the toilet’s incoming
electric power wiring. The “full” signal from the holding
tank can be generated by an optional Dometic Tank
Monitor system.

A VacuFlush 4800 series toilet is part of a total
sanitation system that includes a vacuum source and
usually a holding tank. Because of the wide variation
of boat types and models, Dometic produces a wide
range of vacuum-generating components, holding
tanks and accessories. The VacuFlush system diagram
(above) provides a general orientation to a typical
vacuum sanitation system.
Vacuum Source: A variety of Dometic vacuum sources
provide vacuum energy to move the waste from the
toilet to the holding tank. All consist of a vacuum
storage reservoir and vacuum pump. These can be
separate or combined units (vacuum generators).
Holding Tanks: Many boats are equipped with a
holding tank, and many of those are SeaLand holding
tank systems. SeaLand tanks are available in many
capacities, and can include pre-installed vacuum
generator, tank level monitor, discharge pump,
and other accessories to enhance the comfort and
convenience of marine sanitation.

MARINE SANITATION REGULATIONS
All boats with xed toilets in U.S. waters and in the waters of some other countries are required to have an
operable marine sanitation device (MSD). The VacuFlush vacuum sanitation system, when installed in a boat, is
a holding tank or Type III system as dened by the U.S. Coast Guard. Type III systems permit operation of the
toilet without direct discharge of untreated waste after every ush. 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 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 visit our website at www.DometicSanitation.com.

IMPORTANT INFORMATION BEFORE OPERATION
1. Make sure all guests understand toilet and seacock operation and that the ushing
instruction label is easy for guests to read. The label is located under the seat.
2. Remember, the vacuum pump starts automatically. Shut off electrical power to
the toilet system before servicing and do not leave the boat with the toilet system
electrical power on.
3. Never use solvents, alcohol, chlorine or caustic chemicals, such as laundry bleach
or drain-opening types, in the toilet system.
4. If the toilet system does not operate properly, refer to the Troubleshooting section
and repair as necessary. If problem persists, contact your local VacuFlush dealer or
see the Customer Service section of this manual.
Label located
under toilet seat.
SYSTEM START-UP
1. Fill freshwater tank.
2. Turn on electrical power and water supply to toilet system.
3. Flush water into system by ushing the toilet ve times (press Flush switch and allow each ush cycle to
complete until vacuum pump stops, about 60-90 seconds each).
TOILET OPERATION
1. Adding More Water To Toilet Bowl
Press Add Water switch until desired water level is attained. Do not
overll toilet bowl. More water is usually added only when ushing
solids.
2.
Flushing The Toilet
Press the Flush switch down for a moment, then release it. Flush
only when the panel’s green “OK to Flush” light is on. Some models
will not ush unless the “OK to Flush” light is on. It takes about one
minute for vacuum to recharge to the proper level for the next ush.
If the red “Do Not Flush” light is lit, the system is either recharging
the vacuum to the proper level, or the holding tank is full. Do not
ush the toilet during these conditions or system clogs may occur.
3. DO NOT FLUSH FOREIGN OBJECTS
CAUTION!
bodily wastes and rapid-dissolving toilet tissue. Do not ush wet
wipes, sanitary napkins, condoms, diapers, razor blades, paper
cups, cotton swabs, food, hair or liquids such as oils or solvents.
Clogging or damage to the toilet or sanitation system may occur.
VacuFlush toilets are designed to ush only water,
