Installation Instructions
Installation Instructions
YOUR 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. The toilet is delivered assembled for righthanded operation. If you wish, both Regular and
Compact Bowl models may be re-assembled with
the pump on the left hand side. The seat and lid
is delivered boxed and unfitted for its protection.
NB: Key numbers, e.g. ('Key 31'), are references to the
exploded view diagram on the back page.
1. Re-assembly for left hand use
If you wish to change the pump mounting from right to left
hand, do so before installing the toilet.
▼ Pull off the hose (key 4) that runs from the pump to the bowl.
▼ Remove the 4 screws (key 31) that secure the pump assembly to
the base.
▼ Lift off the pump assembly and leave the base valve gasket (key
16) on its 3 locating pegs.
▼ Remove the 4 bolts (key 11) that secure the bowl to the base.
▼ Rotate the bowl 180° and re-secure it, using the nylon washers
(key 14) to protect the ceramic from the stainless steel washers
and nuts (key 13,12).
▼ Rotate the pump assembly 180° and re-secure it.
▼ Rotate the push-fit intake elbow (key 6) 180° and refit the hose
between the pump and the bowl.
2. Location
▼ Select a location that will give sufficient clearance all round 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 50mm (2") wider
and 50mm (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 lid should be able to swing up and over at least
110°, so that they will not fall forward when the craft heels or
pitches. When they are swung up they must be supported so
that the hinges are not strained
4. Through Hull Fittings
YOU WILL need:
■■ 19mm (
▼ Follow the seacock manufacturer's own instructions concerning
▼ Ensure the inlet seacock is positioned where it will be below the
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.
FOLLOW THESE INSTRUCTIONS!
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 full bore marine quality valves MUST be
fitted to the hoses where they are easily accessible.
USE SEACOCKS!

HAZARD RISK:
Accidental Damage.
CAUTION: Use lever operated, full bore marine
seacocks and valves. The use of screw-down gate
valves is not recommended.
5. 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.
5.1 Pipework - General
instructions for all options
▼ Rotate the intake seal (key 5) so that the elbow points upwards.
YOU WILL need:
■■ Spiral reinforced smooth bore flexible hoses for both the 19mm
3
/4") id inlet and the 38mm (11/2") id outlet pipework
(
■■ Two stainless steel worm-drive hose clips for every hose tail
connection (4, 6 or 8).
▼ 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.
▼ Avoid sharp bends in the hoses that may cause them to become
kinked.
▼ Keep all pipework lengths as short as possible, whilst complying
with these instructions. Unnecessary inlet or outlet hose length
just makes the toilet harder to pump.
▼ 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 of it in hot water.
CAUTION: Do not apply flame to the hose. Do not
apply flame or any heat to the plastic hose tails on the
toilet. Do not use oils, greases or synthetic lubricants.
Do not apply sealing compounds to any hose
connections. Do not over tighten hose clips. Any of
these actions may result in cracking or breakage of the
plastic parts of the toilet.
▼ 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 outlet connections are watertight.
▼ The Discharge Elbow (key 34) may be rotated 360° to suit your
installation. Always slacken the 2 securing screws, adjust the
discharge elbow to the required position and re-tighten the 2
securing screws BEFORE you connect the hose to it.
CAUTION: Failure to follow this procedure may result in
leaks between the discharge elbow and the pump
cylinder.
▼ Replace the white hose with a longer length of 19mm (
hose and arrange it to form an anti-syphon loop whose highest
point is at least 20cm (8") above the highest possible waterline,
and fit the Vented Loop at the highest point.
▼ Secure the ends of all hoses with two stainless steel worm-drive
hose clips.
CAUTION: Do not position the ventilated anti-syphon
loop between the inlet seacock and the flushing pump
inlet, as it will make the flushing pump difficult to
prime, harder to pump and may prevent it from
working at all.
HAZARD RISK:
Bowl Rim Below Waterline
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 20cm (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 ventilated
anti-syphon loop MUST be fitted in any pipework connected to a
through-hull fitting, irrespective of whether inlet or outlet.
USE VENTED LOOPS!
SPECIAL NOTE 1: The smaller bore inlet pipework is more hazardous
than the larger outlet pipework. Unless there is a ventilated antisyphon 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. Although moving the Flush Control Lever
(key 23) to the "Shut" position will restrict the flow, this lever CANNOT
be relied upon as a shut-off valve.
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.
5.2 Inlet Pipework - 2 options
Option 1: Toilet below the waterline
Option 2: Toilet always above the heeled waterline

3. Mounting
YOU WILL need:
■■ 4 x 8mm (5/16") diameter stainless steel bolts of length to suit the
thickness of the mounting surface.
■■ 4 stainless steel nuts, preferably self-locking. If you do not use
self-locking nuts you will need some nut-locking compound.
■■ 8 large stainless steel washers not more than 21mm (
diameter.
■■ A small 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 4 bolt holes
on the mounting surface. Remove the toilet and drill 4 vertical
holes of 9mm diameter through the mounting surface.
▼ Apply a bead of white silicone sealant to the outer rim of the
bottom base.
▼ Bolt down the toilet and tighten the fastenings securely. If you
are not using self-locking nuts, use nut-locking compound.

HAZARD RISK:
Pipework Becomes Loose
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 may 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.
USE HOSE CLIPS!
YOU MUST fit a 19mm (3/4") Vented Loop fitting, Jabsco part number
29015-0000.
▼ Run the inlet hose by the most direct route from the inlet
seacock to the flushing pump inlet tail.
▼ Remove the white hose supplied with the toilet, which connects
the flushing pump outlet tail to the elbow (key 6).
YOU MAY need A 19mm (3/4") non-return valve, Jabsco part number
29295-0011
▼ Run the inlet hose by the most direct route from the inlet
seacock to the flushing pump inlet tail.
▼ For maximum convenience of use, install a 19mm (
non-return valve next to the inlet seacock, which will ensure that
the pump remains primed in between usages.
