Water Supply - Vetus HATO Instructions D'installation Et Manuel D'utilisation

5.4 Water supply

Use copper piping or hoses for
the water supply.
Cut off the water supply pipe at
about 150 mm under the frame.
Clamp the supply pipe firmly.
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 must be fitted in the water supply pipe.
If external water is to be used then this must be properly filtered.
5.5 Outlet
Use ø 25 mm hose (for example
'Vetus smell proof outlet hose' ø
25 mm) for the outlet hose.
Cut off the outlet hose at about
180 mm under the frame.
Clamp the outlet hose firmly.
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 either through
the supply pipe or the outlet. An air vent must be fitted at the
highest point in the supply pipe and/or the outlet in order to
prevent siphoning (see the installation examples).

5.7 Fitting a false wall
Position the false wall (e.g. plas-
terboard) against the frame.
Drill 2 holes ø 25 mm through the
false wall in the right place so that
3/4"
it will be fitted right up against the
frame.
HATO 12
Fit a hatch opening in the false wall so that the ball valve in the
(rear view)
supply pipe will always be accessible without having to dis-
mantle the toilet pot.
Position the packing supplied (E)
correctly against the false wall
with the threaded studs going
through the holes in the packing.
Draw the hole to be cut out on the
inside of the packing.
ø 25
Remove the packing.
Cut out the hole in the false wall.
(rear view)
If the false wall is to be tiled the
tiles will have to be cut to fit the
opening in the false wall.
Before permanently fitting the toi-
let pot check once more that the
threaded studs have the right
length.
Position the packing (E) over the
threaded studs.
