Vacuum Flush Head System (If Equipped)

OVERFILLED HOLDING TANK HAZARDS!
NEVER overfill the holding tank! An overfilled holding tank is both a serious public
health hazard and a product/property damage hazard!
 When the holding tank is full, flushing the toilet will force clogging-waste into the tank's
vent system.
 If the vent system becomes clogged, further toilet flushing will dangerously pressurize the
holding tank.
 The possible hazards of a pressurized holding tank range from human waste leaking
through damaged tank fittings, all the way up to an explosive rupture of the tank.
Perform the following steps to avoid overfilling the holding tank:
 Frequently check the content level in the holding tank by looking at the side of the tank.
 After EVERY trip, and at EVERY opportunity during long trips: Empty and flush out the
holding tank, and add marine holding tank deodorizer.
 Use rest rooms onshore whenever possible to reduce the amount of waste flushed into the
holding tank.
 Before using your vacuum
flush head, read the vac-
uum flush head's operation
and maintenance manual.
 The vacuum flush head sys-
tem uses freshwater from
the fresh-water tank and a
vacuum pump to flush
waste from the toilet into
the holding tank.
 The holding tank is
plumbed to a fitting on the
deck for dockside pump-
out. This fitting is marked
WASTE.
 Before each trip make sure
the holding tank vent sys-
tem is working properly.
Check for obstructions such
as insect nests at the vent
thru-hull fitting.
 Immediately replace the
vent filter if:
a. Flushing causes a bad
odor.
b. The holding tank has been overfilled.
c. The holding tank is difficult to empty.
 Never flush anything except human waste and rapid-dissolving boat or RV toilet tissue into the holding tank.
 Whenever possible use onshore rest rooms instead of your onboard head. Using your onboard head only
when there is no other option will help you avoid overfilling the holding tank.
 Look at the side of the holding tank often to check the content level.
 Empty the holding tank at every opportunity.
