6 Installation
Determine whether the water supply to the toilet
will be fresh water or sea water, above or below
the vessel's water line, and then follow the
appropriate instructions for the installation.

6.1 Above water line system
For layout details, see "Above water line system"
on page 7.
The following information is important:
• The toilet bowl rim must be a minimum of
8.0 in. (203 mm) above the highest possible
water line at full heel.
• Vented loops must be a minimum of 8.0 in.
(203 mm) above the highest possible water
line at full heel. For optimum toilet operation,
install the vented loop as close to 8.0 in.
(203 mm) height as possible.
• Place vented loops near the center of the
boat to minimize fluctuation of the water line
height.
• Maximum seawater pump lift is 4 ft (1.2 m).
• Maximum discharge head is 4 ft. (1.2 m).
6.2 Below water line system
For layout details, see "Below water line system"
on page 8.
The following information is important:
• The 0.75 in. (19 mm) vented loop must use
either a duckbill valve or electric normally-
open solenoid valve.
• Vented loops must be a minimum of 8.0 in.
(203 mm) above the highest possible water
line at full heel. For optimum toilet operation,
install the vented loop as close to 8.0 in.
(203 mm) height as possible.
• Vented loops should not exceed a maximum
of 2 ft (0.6 m) above the water line.
• Place vented loops near the center of the
boat to minimize fluctuation of the water line
height.
• Maximum seawater pump lift is 4 ft (1.2 m).
• Maximum discharge head is 4 ft. (1.2 m).
6.3 Inlet plumbing
WARNING: Flooding hazard.
Do not connect sea water flush toilet inlet
line to a pressurized freshwater system.
This will result in a continuously running
freshwater pump, which can possibly
overflow the toilet bowl, and flood the
boat. Failure to obey this warning could
result in death or serious injury.
