and the ﬂushing action begins. Be sure to hold
lever down for 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.
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 the manufacturer’s manual for
3. Do Not
Figure J7: Overboard Discharge Option
The discharge pump must be used to
discharge waste overboard. However, DO
NOT use the discharge pump to discharge
waste at a pumping station.
Figure J5: VacuFlush Operations
To operate the overboard discharge system:
The discharge valve is located in the engine
compartment labeled HEAD DISCHARGE. To
open, turn the valve so that the handle is parallel
to the ﬂow of the valve. The waste deck plate
cover must be tightened securely for the over-
board discharge system to operate.
Turn ON the overboard discharge switch which is
located in the head on the switch panel. Allow the
discharge pump to run until the storage tank is
empty. The sound of the pump’s motor load and
speed will change when the tank becomes empty.
Turn the overboard discharge switch off.
Figure J6: VacuFlush Waste Holding Tank System
Turn the head discharge valve handle to the
closed position, and secure it. This thru-hull valve
(seacock) must be closed to prevent water from
being forced back into the system.
B. Head With Overboard Discharge
This option is available on the V335 models. The head
toilet operations are the same as the systems de-
scribed earlier. A discharge pump is incorporated into
the VacuFlush waste holding tank system. An
additional hose with a seacock has also been installed
for overboard discharge. Refer to Figure J7.
