WARNING:
HAZARD RISK: Flooding.
FOLLOW THESE INSTRUCTIONS!
If the installation of the toilet results in it being connected
to ANY through-hull fitting that may possibly be below
the waterline at ANY time, whether when the craft is at
rest, underway and heeling or rolling or pitching, you
must install the toilet in accordance with these Installation
Instructions. If you do not, water may flood in, causing
the craft to sink, which may result in loss of life.
WARNING:
HAZARD RISK: Accidental Damage.
USE SEACOCKS!
If the toilet is connected to ANY through-hull fittings and if
the toilet or pipework is damaged, water may flood in
causing the craft to sink, which may result in loss of life.
Therefore, if you are making connections between the
toilet and ANY through-hull fittings that may possibly be
below the waterline at ANY time, full bore seacocks must
be fitted to those 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 this, then secondary bore
marine quality valves MUST be fitted to the hoses where
they are easily accessible.
CAUTION:
Use lever operated, full bore marine
seacocks and valves. The use of screw-
down gate valves is not recommended.
Pipework - selection of correct method
YOU MUST select the correct method for the
inlet pipework from 2 options and for the outlet
pipework from 4 options, according to whether
the toilet is above or below the waterline, and
to whether it discharges the waste overboard
or into an on-board holding tank.
WARNING:
HAZARD RISK: Flooding.
USE VENTED LOOPS!
If the toilet is connected to ANY through-hull fittings, 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 8" (20cm)
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 ventilated anti-syphon loop
MUST be fitted in any pipework connected to a through-
hull fitting, irrespective of whether inlet or outlet.
SPECIAL NOTE 1:
The smaller bore inlet pipework is
more hazardous than the larger outlet pipework. Unless
there is a ventilated anti-syphon loop in the inlet
pipework, water will flow into the bowl whenever both the
inlet seacock is open and the rim of the bowl is below
the actual waterline.
SPECIAL NOTE 2:
Making a loop in the hose without
fitting a vent may be just as hazardous as no loop at all,
because water may syphon over a loop. It is the vent that
actually prevents the syphon.
WARNING:
HAZARD RISK: Pipework Becomes Loose.
USE HOSE CLIPS!
If the toilet is connected to ANY through-hull fittings and
if the pipework becomes disconnected, either from a
through-hull fitting or seacock, or from the toilet or any
secondary valve, water may flood in and cause the craft
to sink, which may result in loss of life.
Therefore the ends of ALL flexible hoses fitted directly
or indirectly between the toilet and ANY through-hull
fitting that may possibly be below the waterline at ANY
time, MUST be secured to the hose tails to which they
are connected, using two stainless steel worm-drive
hose clips.
Pipework - General instructions for all options
YOU WILL need:
Two stainless steel worm-drive hose clips for every
•
hose tail connection.
Please ensure the pump guard strainer is fitted to
•
protect the rinse pump. the strainer should be fitted
in an accessible position for servicing/cleaning.
Secure the hose runs so that the hoses cannot move
•
and chafe, and so that they do not exert any leverage
on the hose tail fittings to which they are connected,
as this may cause adjacent joints to leak.
Spiral reinforced smooth bore flexible hoses for
•
both the ¾" (19mm) inlet and the 1½” (38mm)
outlet pipework.
Avoid sharp bends in the hoses as this may cause
•
them to become kinked.
Keep all pipework runs as straight and as short as
•
possible, avoiding rising and falling over obstructions
which creates airlocks.
If it is difficult to fit the hose onto the hose tails of the
•
toilet or seacocks, lubricate it with water, or soften
the hose by dipping the end in hot water.
Secure the ends of all hoses to the hose tails with
•
two stainless steel worm-drive hose clips, ensuring
that all inlet connections are airtight, and that all
the outlet connections are water tight.
