2 General safety instructions
The manufacturer will not be held liable for claims for damage resulting from the following:
• Faulty installation or connection
• Damage to the unit from mechanical inuences, misuse or abuse
• Alterations to the unit without express written permission from the manufacturer
• Use for purposes other than those described in this manual
2.1 Warnings – marine applications
The following statements must be read and understood before installing, servicing and/or
operating this product on a boat. Modication of this product may result in property damage.
Dometic recommends that a qualied technician or electrician install or service this product.
Equipment damage, injury to personnel or death could result from improper installation. DOMETIC
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.
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull ttings, ALWAYS close seacocks when
toilet is not in use (even if boat is unattended for a brief period). All passengers must be
instructed on how to close valves when the toilet is not in use. Failure to do so can result
in ooding which can cause loss of property and life.
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 if boat is unattended for a brief period).
Failure to do so can result in ooding which can cause loss of property and life.
Caution! Hazard of Flooding
Before beginning any work on this product, be sure that all electrical power to the toilet
system has been turned off and that seacocks are in the CLOSED or OFF position. Failure
to do so can result in ooding which can cause loss of property and life.
Caution!
Overlling the holding tank 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 recommends using the “full” tank shut-down relay in the toilet’s
electronic control module. The “full” signal from the holding tank can be generated by an
optional Dometic DTM01C tank monitor or DTM04 four-level tank monitor system.
3 Intended use
The Dometic VacuFlush toilet vacuums waste from the bowl and pumps it to a holding tank or other
efuent storage/disposal system. Operated by a foot pedal, the toilet allows the user to add water to
the bowl (before using or ushing) by slightly raising the pedal, and to ush the toilet by pressing the
pedal down. An optional status panel activates lights to indicate when the toilet is activated, when
the toilet is ready to ush, and when the toilet is not ready to ush due to recharging vacuum.
3.1 Benefits
Convenient pedal-operated flush. Add water or ush with the foot pedal.
Home-like comfort in small space. Toilets feature a full-size wood seat with large opening and
deep bowl for premium comfort.
Water conservation. Water consumption per ush is determined by how long the pedal is pushed.
VacuFlush pedal-ush toilets typically use about 1 pint (0.5 l) per ush when the pedal is pressed
for 3 seconds.
Integrated check valve. VacuFlush 5000 series toilets use an in-line check valve to prevent backow in event of negative pressure in the water supply line.
“OK to Flush” and “Do Not Flush” indicator lights (option). When equipped with an optional
VacuFlush status panel, a green light indicates when proper vacuum is achieved and toilet is ready
to ush. Red light indicates when vacuum level is too low for a ush to occur. Vacuum recharges
in about one minute after ushing.
Automatic “full tank” shut-down (option). When connected to an optional holding tank level
indication system and the holding tank reaches full level, the VacuFlush toilet’s vacuum generator
will shut its electrical power off. This safety feature prevents overlling the holding tank, which
may cause damage to the boat.

2. Turn on electrical power and water supply to VacuFlush toilet system.
3. Flush water through entire toilet system by pressing ush pedal for about 15 seconds.
Release pedal, allowing pedal to snap back into original position. Vacuum pump will operate for
about one minute, then shut off.
6.2 Normal toilet operation
ADD WATER TO TOILET BOWL
Lift ush pedal until desired water level is achieved. More water is usually added
only when ushing solids. (If pedal is raised too long, toilet bowl can overow.)
FLUSH TOILET
Press ush pedal down for about 3 seconds, then release it. Allow pedal to snap
back into original position to assure vacuum seal. It takes about one minute for
vacuum to recharge for the next ush. A small amount of water remains in bowl after
every ush.
If ush pedal is accidentally released before efuent leaves bowl, do not ush again
until vacuum pump stops running.
DO NOT FLUSH FOREIGN OBJECTS
CAUTION! Flush only water, bodily wastes and rapid-dissolving tissue paper.
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 system may occur.
Note
Make sure all guests understand toilet operation before use.
6.3 Indicator lights (requires optional VacuFlush status panel)
“OK TO FLUSH” INDICATOR
On a VacuFlush status panel, a steady green “OK to Flush” light indicates when the toilet is ready
to ush.
“DO NOT FLUSH” INDICATOR
VacuFlush status panels include a red “Do Not Flush” light to indicate two toilet system conditions:
1. vacuum level in toilet system is not sufcient for complete ush.
2. holding tank is full and should be pumped out (only when connected to an optional holding
tank level indication system). When the red light is on, electrical power to the toilet automatically
shuts off to prevent possible overlling of the holding tank.

VacuFlush Pedal-Flush ToiletOperation
6.4 Locking foot-pedal open for pump-out (models 5146, 5147, 5149, 5149)
VacuFlush® 5140 series vacuum toilets include a hold-open pedal lock. When installed in a toilet
system with a VHT12/24, VHT4500 or VHT5200 vacuum holding tank, the pedal lock holds the ush
ball open to allow positive air pressure into the vacuum holding tank during pump-out. This helps
assure thorough discharge of the vacuum holding tank.
Note
Before pumping out holding tank, turn off water supply to toilet and electrical power to
vacuum pump. Follow steps below to assure thorough tank discharge.
1. a. Press down fully on Pedal, then b. press Lock.
2. Slowly bring Pedal up while holding Lock down against Pedal until Pedal stops. The Lock
prevents the ush ball inside the toilet bowl from closing completely.
3. Pump out holding tank.
4. After pump-out is complete, press down on Pedal fully, then release to close ush ball.
