WARNING!
HAZARD OF FLOODING – If the toilet
system is connected to ANY through-the-hull ttings,
properly installed seacocks MUST be installed in all
piping connected to through-the-hull ttings. Seacocks
MUST be easily accessible to all users of the toilet
system or secondary valves tted in hoses where they
are easily accessible. ALWAYS close seacocks when
toilet system is not in use (even if boat is unattended
for a brief period. All valves MUST be full bore valves
and marine quality. Screw-to-close gate valves are not
recommended. Failure to comply can result in ooding
which can cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet is
connected to ANY through-the-hull ttings, ALL
exible hoses must be of marine sanitation quality
and must be secured to ANY ttings (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.
Failure to comply can result in ooding which can
cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet rim is
below the waterline at ANY time (during any conditions
of heel, load or trim) and is connected to ANY through-
the-hull ttings, properly positioned ventilated (vented)
loops MUST be installed in intake* or discharge piping
to prevent potential back siphonage of seawater into
the boat. Failure to do so can result in ooding which
can cause loss of property and life.
* if connected to raw water
WARNING!
HAZARD OF FLOODING – 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
for a brief period). Failure to comply can result in
ooding which can cause loss of property and life.
WARNING!
HAZARD OF FLOODING – If toilet uses
raw water for ushing 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
ood the boat. Failure to comply can cause loss of
property and life.
WARNING!
HAZARD OF FLOODING – Before
beginning any work on this product, be sure that all
electrical power to the unit has been turned off. Failure
to do so can result in ooding which can cause loss of
property and life.
WARNING!
HAZARD OF SHOCK OR FIRE –
Always use recommended fuse, circuit breaker and
wire size. Failure to do so can result in re that can
cause the loss of property and life.
CAUTION:
Overlling 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 strongly recommends the addition of a “full”
tank safety shut-down relay to the toilet’s incoming
electric power wiring. The “full” signal from the holding
tank can be generated by an optional Dometic Tank
Monitor system.
