Applications
Jabsco Quiet Flush electrically operated marine toilets can
be installed in both power and sailing craft, either above
or below the waterline, for use on sea, river, lake or canal.
CAUTION: Jabsco electrical toilets are
designed specifically for marine use. Consult
Jabsco for advice about possible non-marine
applications.
A typical installation may discharge the waste either over-
board (provided that your national and local regulations
allow this), or into a treatment system or into an on-board
holding tank (U.S.C.G. Marine Sanitation Devices Type I,
II and III).
Installation Instructions
The toilet is just one part of a system. Correct installation
of the whole system is essential if you want the toilet to
perform properly, operate reliably and safely, and give
satisfactory length of life.
Location
• Select a location that will give sufficient clearance all
round and above the bowl.
• The mounting surface must be flat, rigid and strong
enough to support the weight of both the toilet and
user. Ensure the surface is at least 2" (50mm) wider
and 2" (50mm) deeper than the base of the toilet and
pump assembly.
• Ensure there is sufficient clearance below the mount-
ing surface to be able to secure the mounting bolts,
and to be able to remove them for maintenance.
• Offer up the seat and lid to the bowl. They should be
able to swing up and over, so that they will not fall
forward when the craft heels or pitches. When they are
swung over they must be supported so that the hinges
are not strained. Remove the seat and lid and put
them aside until the installation is complete.
Mounting
Hardware Requirements:
• 3 x 5/16" (8mm) diameter stainless steel bolts or lag
bolts of length to suit the thickness of the surface
mounting
• 3 stainless steel nuts, preferably self-locking. If you do
not use self-locking nuts you will need some nut-lock-
ing compound.
• 6 stainless steel 5/16" (8mm) washers, 3 under the
bolt heads and 3 under the nuts if used.
• A tube of white silicone sealant.
• Offer up the toilet in the selected position and, using
the holes in the base as a guide, mark the positions
for the 3 bolt holes on the mounting surface. Remove
the toilet and drill 3 vertical holes of 5/16" (8mm)
diameter through the mounting surface.
• Now complete all of the rest of the installation before
you secure the bowl.
Through-Hull Fittings
Hardware Requirements:
• 3/4" (19mm) bore seacock for the rinse pump and, if
you are discharging the waste over board, a 1" (25mm)
bore seacock for the waste outlet. An additional 1" to
1-1/2" (25mm to 38mm) adapter is supplied with the
toilet.
• Follow the seacock manufacturer's own instructions
concerning materials and methods of installation.
• Ensure the inlet seacock is positioned where it will be
below the waterline at all times when the craft is un-
derway, and also ensure that any other outlet seacock
is both aft of, and higher than, the inlet seacock.
