5.4 Water supply

SMTO 24
Fit a ball valve with 3/4" external connection to the supply pipe
and make sure that this will always be accessible.
If there is already a pressurised water system on board the sup-
ply hose can be connected to this system. The pressure must
be at least 1.5 bar; this is the minimum pressure required to
allow the toilet to function properly.
If the water pressure system is less than 1.5 bar or if external
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 fit-
ted in the water supply pipe.
If external water is to be used then 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 pipe.
5.5 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
mm 2 (for 24 V).
5.6 Prevention of siphoning
If the toilet is below or less than 50 cm 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 examples).
