Installation instructions

Introduction
If the installation of the toilet results in being connected to any through-hull
fitting 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 flood in, which may
result in loss of life.
ACCIDENTAL DAMAGE
If the toilet is connected to any through-hull fitting and if the toilet or the
pipework are damaged, water may flood in, causing the craft to sink with a
consequent possible loss of life. For this reason, if you are making connec-
tions between the toilet and any through hull fitting that may be possibly
situated below the waterline, fullbore seacocks must be fitted to such hull-
fittings, to allow them to be shut off.
The seacocks must also be positioned where they are easily accessible 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 fitted 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 remain-
ing 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 fitting and if the rim of the bowl
falls below the waterline, water may flood 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 fitted in any pipework connected to a through-hull fitting,
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 flow into the bowl whenever both the inlet seacock is
opened and the rim of the bowl is below the actual waterline.
Although moving the flush control lever to the "Shut" position will restrict
the flow, this lever cannot be relied upon as a safety device. To 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.
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-fit intake elbow 180° and refit the hose between
the pump and the bowl.
Assemble the bowl on the top of the base, using the attached bolts, wash-
ers 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 flat, 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 sufficient 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.
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.
• Drill: Diameter 9mm.
• Silicone sealant, white.
If you do not use self-locking nuts, you will need some nut-locking com-
pound
