2.4 General safety messages
WARNING: Flooding hazard. Failure
to obey the following warnings
could result in death or serious
injury.
• If the toilet is connected to any through-
the-hull fittings, properly installed seacocks
must be installed in all piping connected to
through-the-hull fittings. Seacocks must be
easily accessible to all users of the toilet or
secondary valves fitted in hoses where they
are easily accessible. All valves must be full
bore valves and of marine quality. Screw-to-
close gate valves are not recommended.
• If the toilet is connected to any through-
the-hull fittings, all flexible hoses must be
of marine sanitation quality and must be
secured to any fittings (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.
• If the toilet rim is ever less than 8 in. (20 cm)
above the highest possible waterline at any
time (during any conditions of heel, load, or
trim) and is connected to any through-the-
hull fittings, properly positioned ventilated
(vented) loops must be installed in intake (if
connected to raw water) or discharge piping
to prevent potential back siphonage of
seawater into the boat. Vented loops must
be equipped with integral check valve that
permits air into line to prevent siphoning.
• If toilet uses raw water for flushing 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 flood the boat.
• Do not connect raw water flush toilet
(models 7160, 7260) to an onboard
pressurized water system.
• Before beginning any work on this product,
be sure that all electrical power to the unit
has been turned off and that the seacocks are
in the closed or off position.

WARNING: Electrical shock and/or
fire hazard.
Follow all local regulations for electrical
installations.
NOTICE:
Overfilling the holding tank can
cause 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 a full
tank shut-down relay. The full signal from the
holding tank can be generated by an optional
Dometic DTM01C tank monitor or DTM04 four-
level tank monitor system.
Follow all local regulations for waste tank
discharge.
