1 EXPLANATION OF SYMBOLS AND SAFETY INSTRUCTIONS
This manual has safety information and instructions to help you eliminate or reduce the risk of
accidents and injuries.
1.1 Recognize safety information
This is the safety alert symbol. It is used to alert you to potential physical injury hazards.
Obey all safety messages that follow this symbol to avoid possible injury or death.
1.2 Understand signal words
A signal word will identify safety messages and property damage messages, and will indicate the
degree or level of hazard seriousness.
indicates a hazardous situation that, if not avoided, could result in death or
serious injury.
indicates a hazardous situation that, if not avoided, could result in minor or
moderate injury.
is used to address practices not related to physical injury.
Iindicates additional information that is not related to physical injury.
1.3 Supplemental directives
Read and follow all safety information and instructions to avoid possible injury or death.
Read and understand these instructions before installation of this product.
Incorrect installation of this product can lead to serious injury.
The installation must comply with all applicable local or national codes, including the
latest edition of the following standards:
U.S.A.
• ANSI/NFPA70, National Electrical Code (NEC)
• ABYC guidelines for marine installations
1.4 General safety messages
Failure to obey the following warnings could result in death, serious injury, or
property damage:
• This product must be installed and serviced by a qualified service technician.
• Do not modify this product in any way. Modification can be extremely hazardous.
• SHOCK OR FIRE HAZARD: Always use recommend fuse, circuit breaker, and wire size. Failure
to do so can result in a fire that can cause the loss of property and life.
• FLOOD HAZARD:
– 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 should be fitted in
hose runs where they are easily accessible.
– If the toilet is connected to any through-the-hull fittings: always close seacocks when
toilet is not in use (even if the boat is unattended for a brief period).

4
EN
Toilets
– Valves must be full-bore valves of marine sanitation quality. Do not use screw-to-close
gate valves.
– Flexible hoses must be of marine sanitation quality and must be secured to any fittings
with two stainless steel, worm-drive, hose-band clamps at each connection. Check
connections frequently for integrity.
– Use properly positioned, ventilated loops when the potential exists for the toilet rim to
fall below the waterline during any heel, load, or trim condition, or when the toilet is
connected to any through-the hull fittings. The ventilated loops must be installed in the
intake (if connected to raw water) and/or the discharge piping.
– Ensure that all electrical power to the toilet is turned off and that seacocks are in the
closed or off position before installing the toilet or performing any maintenance.
– If the toilet uses fresh water for flushing 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 if boat is unattended for a brief period).
– 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 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.
RISK OF PROPERTY DAMAGE: Failure to obey the following notices may cause
damage to the toilet or toilet system.
• Only flush water, bodily wastes, and rapid-dissolving toilet tissue.
• Do not overfill the holding tank, or serious damage can occur to the sanitation system.
Overfilling the holding tank can rupture the holding tank or release tank contents into the
bilge.
• This toilet system is not intended for raw water flush toilet systems and is not designed to
flush with seawater. Only use a fresh water supply.

General guidelines
• Follow all applicable local and national regulations, codes, and standards
• All water supply system plumbing should be 1" ID with a recommended 100 PSI minimum
working pressure rating
• Water inlet strainer: 1" ID, 40 mesh
• Pressure gauge: 0 – 100 PSI
Water pump guidelines
• Grundfos MQ3-35 or equivalent is recommended
• 1" NPT connections
• Internal pressure switch: 50 PSI cut-out, 30 PSI cut-in
• MQ3 Pump draw: 8 A @110 V, 4 A @ 220 V (pumps vary by manufacturer)
• 15 gpm required (MQ3 pump rated at 22 GPM max flow with no restrictions)
• Choose a pump with adequate suction li capability for pump installation parameters (MQ3
pump has 25' of suction life capability, but varies depending on horizontal run)
Potable water pressure (accumulator) tank guidelines
• Amtrol Well-X-Trol WX-105-PS or equivalent is recommended
• 3/4" NPT, or larger connections
• 5 gallon total volume, 1.8 gallon drawdown @ 30/50 PSI
• Air pressure charge: 2-4 PSI below pump cut-in pressure
• Recommended to use one five-gallon accumulator tank for up to six heads
Pressure relief valve guidelines
IInstallation of a pressure relief valve is recommended by the accumulator tank
manufacturer in order to protect the fresh water system in case of pressure switch
malfunction.
• Install near accumulator tank and pump
• Set to open at excessive water system pressures

10
EN
Toilets
Electric rim wash valve guidelines (inside toilet)
• 1/2" NPT connection
• 1/2" plumbing to the toilet. If using a single water supply line, this 1/2" branch must intersect
with the main 1" distribution line prior to the electric high-flow water valve.
Electric high-flow water jet valve guidelines
• Electric high-flow water jet valve and maintenance ball valve supplied with every toilet
• 1" NPT connections
• Place water jet valve closest to toilet and the maintenance ball valve farthest from the toilet
– Refer to direction arrow on top of the water jet valve inlet port
• In-line strainer factory-installed in the water jet valve inlet
– Cone shape protrudes out against the direction of water flow, away from the center of
the valve, and is pointed towards the maintenance ball valve
• Water jet valve has a small white manual override lever located by the solenoid:
– Place in vertical position for correct electrical operation
– Place in horizontal position to manually test the water system
Discharge plumbing guidelines
• Keep all lines as short and straight as possible
• Minimum downhill slope required: 1/8" per foot
• 1-1/2" ID pipe or 1-7/8" ID hoses required
– For 1-1/2" pipe:
• Requires drain, waste, and vent (DWV) pipe fittings with sweeping changes of
direction
• Do not use schedule 40 or 80 fittings with tight turns
• Install unions, as necessary, for service
– For 1-7/8" hose, eliminate hose sags and low spots
Check valve guidelines
• Flapper style supplied with every toilet
• Spring check: 1"
• Install valve:
– Close to the toilet
– On the discharge side of the toilet plumbing
– Before the waste line joins with any common discharge line
– When open, the flapper “hinge” must be at the highest possible location
– So the flapper opens in-line with the direction of the water flow
• When gluing the valve in place, do not allow excess glue to contact the flapper
• When flushing overboard through the seacock:
– Loop inside the toilet must be above the waterline
– Seacock must be 1-1/2" full-flow and located no lower than 12" below the water line

IPlan the switch/status panel location, if applicable, so that the wiring cable and
connections are installed in locations that always remain dry. Use the length of the
provided wiring cable to help space the electrical connections at the proper distance
from the toilet.

IThe discharge floor flange should be installed directly on the finished floor. However, if
the bottom of the floor flange and the bottom of the toilet must be at different heights,
make sure the bottom of the discharge floor flange rim is within 3/8” (10 mm) of the
bottom of the toilet, regardless of the installation method.
