Using Vacuum Style Toilet
To use the on board toilet fi rst make sure the 12 volt head
system breaker is activated at the main control panel. If
using dockside water make sure water is connected from
the marina spigot (faucet).
The wall control switch is used to add water to the bowl
and to fl ush the toilet. Select cycle information is noted
below. For more complete information, refer to the toilet
vendor information located in the information packet.
1. To add water (est. 17 ounces each cycle ) to the bowl
press the add water button momentarily and release. The
system prevents overfi lling the bowl.
2. To fl ush the bowl press the fl ush button momentarily
and release. The attached bowl motor will macerate the
waste and fl ush it. The cycle ends with a small amount of
water being added to the bowl to help prevent odors. This
completes the minimal water usage fl ush cycle.

The onboard head system
features a toilet taking
advantage of minimal water
usage. The system features
vitreous ch ina bowl,
minimal maintenance, easy
cleaning and a wall switch
keyboard.
The toilet is powered by
12 volt DC electricity and
is controlled by a 30 amp
breaker located at the ship’s
main DC control panel.
Under normal conditions,
the head system operates from the onboard fresh water
tank. If dockside water is being used the toilets still draw
water from the freshwater tank.
A Few Notations About The Head System:
• Only human waste and toilet paper should be put in
the toilet. Never fl ush foreign materials such as paper
towels, pre-moistened wipes, condoms, feminine
hygiene products, dental fl oss or household garbage
down the toilet.
• Always disconnect the dockside water system if boat
is left unattended to avoid property damage due to
leakage.
• Refi ll the toilet as soon as possible after emptying the
bowl to prevent objectionable odors.
• Use only RV-Marine toilet tissues that disintegrate
rapidly. Do not use household type tissues.
• If repairs are needed, use only a trained and qualifi ed
marine technician or electrician.
