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
Instead of just one
grey water tank, it
is also possible to
distribute the total
capacity required
over two or more
tanks.
Arrange the tanks,
and thus the
weight, evenly over
the ship.
(F = Fuel, W = Water, WW = Waste Water)
Install the tank so that it is
easily accessible for inspec-
tion.
Also ensure that there is suf-
ficient free space over the top
of the tank for the hose con-
nections. These must be eas-
ily accessible during installa-
tion. The tank should be 1 cm.
free all round from bulkheads
or other tanks, to provide ven-
tilation.
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
securing the tank.
Fix the tank in place with the straps from the connector kit, these
will accommodate expansion of the tank.

Inspection cover and fittings
Always fit the inspection
cover on the top of the tank!
Use the drill stencil supplied to
make the hole for the cover.
Finish the hole free of burrs.
Drill the holes for the fittings
(43 mm (1 ∕ ") diameter) and
11
1 6
suction tube (57 mm (2 ∕
1
diameter) in the top of the
tank.
Choose the position of the
fittings so that when the ship
is beached on its side, waste
water cannot run back to the
shower, wash basin, toilet,
etc., or flow outside via the
tank air-relief.
Clean saw dust and drill shavings from inside the tank.
Fit the inspection cover in the tank
using the gasket supplied. Screw the
cover tight against the backing ring
using the screws supplied.
Assemble the fittings and the suc-
tion tube with the gasket rings sup-
plied. Tighten the nuts using the
wrench, never with
water-pump pliers.
Do not tighten the
nuts excessively.
After 2 days check
that the connec-
tor nuts are still
tight, tighten more
securely if required.
Repeat this after 4
days.
To prevent blockag-
es caused by hairs
and coarse waste in
particular, all fittings
should have burrs removed internally, local narrowing should
be reduced to a minimum and any changes in pipe diameter
should be done using conical adapters or large radii.
