Outlet
You must use a 25 mm (1") or 38 mm (1 ½") Vented Loop fitting
•
Arrange the outlet hose, so that its highest point is at least 20 cm
(8") above the waterline or holdingtank, and fit the Vented Loop at the
highest point.
•
Run the outlet hose from the toilet to the vented loop
•
Run the outlet hose from the vented loop to the seacock or holdingtank
Toilet above the waterline or above Holdingtank
Inlet
20 cm
8"
•
Run the inlet hose by the most direct route from the inlet seacock to a
non return valve.
•
Run the inlet hose from the non return valve to the flushing pump inlet
tail.
•
For your maximum convenience of use, install an in-line non-return
valve next to the inlet seacock which will ensure that the pump stays
primed in between usages.
Outlet
•
As close as possible to the toilet rise the outlet hose 20 cm above the
base to retain water in the bowl. Make sure the outlet hose stays in this
position.
•
Connect outlet hose connection on the toilet to the seacock or holding
tank.
Safety
Ensure that these instructions reach the owner, the skipper or the operator
of the craft, as it contains important safety information ON COMPLETION
OF Installation: Shut the flush control close both seacocks

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
con¬nections between the toilet and any throughhull 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 screwdown 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 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,
ir¬respective of whether inlet or outlet. USE VENTED LOOPS!
Special notes: 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 mounting surface must be flat, rigid, and strong enough to sup-
port 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.
