Installation
General
When choosing a place for the tank and for the deck filler cap,
take the following into account:
The suction hose should be as short as possible, must go
directly down to the tank and be as straight as possible.
The space in which the tank is placed should be properly ven-
tilated.
Position
Several toilets may be connected to a single tank. Extra fittings
are also available.
Position the tank as close as possible to the toilet to avoid dirty
water flowing back into the toilet from the tank when the boat
heels.
Arrange the tanks, and thus the weight, evenly over the ship.
Install the tank so that it is easily accessible for inspection.
Also ensure that there is sufficient free space over the top of the
tank for the hose connections. These must be easily accessible
during installation. The tank should be 1 cm. free all round from
bulkheads or other tanks, to provide ventilation.
Make sure that the
foundation for the
tank is strong enough
to locate it securely.
The tank will increase
in size slightly when
filled. Take this into
account when secur-
ing the tank. Attach the
tank using the stainless
steel rings supplied.

Inspection cover and fittings
The inspection cover and the fittings are pre-assembled in the
upper section of the tank.
Use the tool provided to fit the fittings in the correct direction.
If required create addition-
al holes on the top of the
tank for extra fittings (43
mm dia.).
Choose the position of
the fittings so that when
the ship is beached on its
side, waste water cannot
run back to the toilet, or
flow outside via the tank
air-relief.
Clean saw dust and drill shavings from inside the tank.
Assemble the fittings with the
gasket rings supplied. Tighten the
nuts using the wrench, never with
water-pump pliers. Do not tighten
the nuts excessively.
After 2 days check that the con-
nector nuts are still tight, tighten
more securely if required. Repeat
this after 4 days.
To prevent blockages caused by
hairs and coarse waste in particu-
lar, all fittings should have burrs
removed internally, local narrow-
ing should be reduced to a mini-
mum and any changes in pipe
diameter should be done using conical adapters or large radii.
The sensor for a dirty water level meter is already fitted in the
top of the tank.
The sensor can be connected only to a Vetus level indicator
for waste water.
Option: Vacuum operated vent valve VRF56
In the top of the tank, drill the hole for the vent valve (ø 57).
