INSTALLATION INSTRUCTIONS
Introduction:
If the installation of the toilet results in being connected to any
through-hullttingthatmaypossiblybebelowthewaterlinewhether
when the craft is at rest, underway, heeling, rolling or pitching, you
must install the toilet in accordance with the present installation
instructions.
Failuretofollowsuchinstructionsmaycausewatertooodin,which
may result in loss of life.
ACCIDENTAL DAMAGE
Ifthetoiletisconnectedtoanythrough-hullttingandifthetoiletor
thepipeworkaredamaged,watermayoodin,causingthecraftto
sink with a consequent possible loss of life. For this reason, if you are
makingconnectionsbetweenthetoiletandanythroughhullttingthat
may be possibly situated below the waterline, fullbore seacocks must
bettedtosuchhull-ttings,toallowthemtobeshutoff.
The seacocks must also be positioned where they are easily acces-
sible to all users of the toilet.
If, for any reason, it is not possible to do it, then secondary full-bore
marinequalityvalvesmustbettedtothehoseswheretheyareeasily
accessible
CAUTION:
USE SEACOCKS! USE LEVER OPERATED, FULL-BORE MARINE
SEACOCKS AND VALVES. THE USE OF SCREW-DOWN GATE VALVES
IS NOT RECOMMENDED.
PIPEWORK LOOSING
All pipeworks must be fastened both in the gate side and in the
remaining ones with a stainless steel hose clamp. Please keep in mind
that an eventual leak might cause the craft to sink, with consequent
loss of life USE HOSE CLAMPS!
BOWL RIM BELOW THE WATERLINE:
Ifthetoiletisconnectedtoanythrough-hullttingandiftherimofthe
bowlfallsbelowthewaterline,watermayoodin,causingthecraftto
sink, which may result in loss of life. Therefore, if the rim of the toilet
is less than 20 cm (8”) above the waterline when the craft is at rest,
or if there is any possibility that the rim of the bowl may be below the
waterlineatanytime,aventedloopmustbettedinanypipework
connectedtoathrough-hulltting,irrespectiveofwhetherinletor
outlet.
USE VENTED LOOPS!
Special notes: The smaller bore inlet pipework is more dangerous
than the larger outlet one. Unless there is a ventilated anti-siphon loop
intheinletpipework,waterwillowintothebowlwheneverboththe
inlet seacock is opened and the rim of the bowl is below the actual
waterline.

make a loop in the hose without mounting a vent may be as hazardous
as no loop at all, because water will siphon over the loop.
IN FACT, IT IS THE VENT THAT ACTUALLY PREVENTS THE SIPHON
1. LOCATION
The toilets base and pump is supplied assembled for a right handed
operation. If you wish, both comfort and compact bowl models may
be reassembled with the pump positioned on the left hand side.
The bowl and the base/pump unit are not assembled. If you want
to change the pump mounting from right to left hand, do so before
installing the toilet.
Change to left hand operation
1. Pull off the hose that runs from the pump to the bowl.
2. Remove the 4 screws that secure the pump assembly to the base.
3. Lift off the pump assembly and leave the base valve gasket on its
3 locating pegs.
4. Remove the 4 bolts that secure the bowl to the base.
5. Rotate the bowl 180° and re-secure it, using the nylon washers to
protect the ceramic from the stainless steel washers and nuts.
6. Rotate the pump assembly 180° and re-secure it.
7. Rotatethepush-tintakeelbow180°andretthehosebetween
the pump and the bowl.
Assemble the bowl on the top of the base, using the attached bolts,
washers and gaskets. The nylon washers are to protect the ceramic
from the stainless steel washers and nuts.
• choose a location which will give enough clearance all around and
above the toilet Ensure that there is room to operate the pump and
that there is access to the drain plug at the end of the base.
• themountingsurfacemustbeat,rigid,andstrongenoughto
support a man’s weight and should be at least 50 mm (2”) wider
and 50 mm (2”) deeper than the base of the toilet.
• youwillneedsufcientclearancebelowthemountingsurfaceto
be able to secure the mounting bolts
• the seat and the lid should be able to swing open at least 110
degrees, in order they will not fall forward when the craft heels or
pitches. When they are swung open, they must be supported so
that the hinges are not strained.
2. MOUNTING:
You need
• Stainless steel bolts: 4 pcs, 8mm (5/16”) diameter of length to
suit the thickness of the mounting surface.
• Stainless steel nuts: 4 pcs preferably self-locking. If you do not
use self-locking nuts you need to add locking compound on the
screws / nuts.
• Stainless steel washers: 8 pcs, large diameter, but not more than
21 mm (13/16”) diameter.
