General safety instructions
Caution! Hazard of Flooding
If 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. Failure to comply can result in
flooding which can cause loss of property and life .
Caution! Hazard of Flooding
If 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* or dis-
charge piping to prevent potential back siphonage of sea water into the boat. Vented loops
must be equipped with integral check valve that permits air into line to prevent siphoning.
Failure to do so can result in flooding which can cause loss of property and life.
Caution! Hazard of Flooding
If toilet uses sea water for flushing at ANY time, a sea water pump controlled by an auto-
matically 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. Failure to comply can cause loss of property and life.
Caution! Hazard of Flooding
Do not connect sea water flush toilet (models 7160, 7260) to an onboard pressurized water
system. Failure to comply can result in flooding which can cause loss of property and life.
Caution!
Do not connect sea water flush toilet (models 7160, 7180) to an onboard potable water
system. Failure to comply could result in contamination of the potable water supply.
Caution! Hazard of Flooding
Before beginning any work on this product, be sure that all electrical power to the unit has
been turned off and that seacocks are in the CLOSED or OFF position. Failure to do so can
result in flooding which can cause loss of property and life.
Caution! Hazard of Shock or Fire
Always use recommended fuse, circuit breaker and wire size. Failure to do so can result in
fire that can cause the loss of property and life.
Caution!
Overfilling 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 recommends using a "full" tank shut-down relay from the "full" signal
generated by an optional Dometic DTM01C tank monitor or DTM04 four-level tank monitor
system.
