INSTALLATION
PLUMBING
WARNING: Hazard of Flooding
Toilets mounted at or below the waterline must
have a vented loop installed in the discharge
line. The top of the vented loop must be a
minimum of 4" (10cm) above the waterline at
the boats greatest angle of heel (see vented loop
manufacturer’s instructions).
Sea Water Models must also have a vented loop
installed between the intake pump and the
toilet bowl.
Double clamp all below waterline connections.
• Hazard of potable water contamination.
Vacuum breaker must be installed with
installations using potable water.
IMPORTANT:
•Fittings and 90° bends should be kept to a
minimum.
• In-Line Strainer must be installed before
the Remote Intake pump. Failure to do so
may void warranty.
•Discharging untreated sewage is restricted
in all U. S. waters within the three-mile
limit. If boating outside of U.S. Boundaries
check with local authorities for their rules
and regulations.
•Thru-hull fittings and seacocks must be
installed where they are easily accessible.
•Use only quality reinforced hoses.
•Secure all hoses properly.
Discharge Lines
1. Connect quality 1 1/2" (38mm) sanitation
hose to discharge fitting on toilet.
2. Run hose to appropriate device (i.e.: treatment
system, holding tank, etc.).
