4.3 Water supply
• Fit a ball valve with 3/4” external connection to the water supply
and make sure that this will always be accessible.
If there is already a pressurised water system on board the supply
hose can be connected to this system. The pressure must be at least
1.5 bar; (21 psi) this is the minimum pressure required to allow the
toilet to function properly.
If the water pressure system is less than 1.5 bar (21 psi) or if raw water
is to be used then a supply pump with capacity of at least 10 litres/
minute (2.2 Imp.Gal/min; 2.7 US Gal/min) must be fitted in the water
supply pipe.
If raw water is to be used this must be properly filtered.
The toilet has a 3/4” connector.
• Connect the flexible water supply hose to the ball valve on the
water supply.

Unpleasant smells caused by faeces will be produced in every
blackwater tank.
The use of sea water for flushing will increase
the smell.
The algae in sea water also produce unpleasant smells.
4.4 Prevention of siphoning
If the toilet is below or less than 50 cm(20”) above the waterline there
is a danger of water siphoning back into the toilet (supply pipe). An
air vent must be fitted at the highest point in the supply pipe in order
to prevent siphoning (see the installation example 1B).
4.5 Control panel or control switch
TMWBP:
• Bore a hole in the wall for the panel. For the dimensions of this
hole, see the drawing under ‘Main Dimensions’.
Place the panel, with its packing, in the wall.
TMWBS:
• Bore a hole in the wall for the switch. For the dimensions of this
hole, see the drawing under ‘Main Dimensions’.
Place the switch in the wall.
• Feed the cable through the hole into the toilet and connect it to
the toilet’s connection.
• Click the finish frame into position over the panel (for TMWBP
model only).
4.6 Electrical installation
• Check that the voltage given on the type plate on the motor is the
same as the voltage on board.
Use batteries with sufficient power to guarantee that the toilet
will work correctly.
• Connect the power supply as shown in the wiring diagram. Fit a
switch and a fuse in the (‘+’) wire.
Use wires with minimum cross section of 6 mm
2
(AWG10) (for
12 V) or 4 mm
2
(AWG12) (for 24 V).
