Vetus WWS B Série Instructions D'installation Et D'utilisation page 8

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 mm
(2 1 / " dia.)).

Tank connections
See pages 26, 27 for a summary of installation examples.
Connect the tank with a good quality reinforced hose. Avoid
sharp bends and kinks or sagging in the hose.
Bracket the hose at not too far apart, regular points, to prevent
the hose sagging. Deposits will collect in these sags, causing a
blockage after time.
The reinforced hose should be an odour-proof waste water
hose and resistant to a limited under- and over-pressure of 0.3
bar (0.3 kgf/cm 2 , 4 psi).
Vetus supplies a hose suitable for waste water.

SAHOSE16, odour-proof waste water hose, 16 mm (
internal diameter
SAHOSE19, odour-proof waste water hose, 19 mm (
internal diameter
SAHOSE25, odour-proof waste water hose, 25 mm (1") inter-
nal diameter
SAHOSE38, odour-proof waste water hose, 38 mm (1
internal diameter.
Fit every hose connection with a good stainless steel hose
clip.
Attach the discharge connection '5' to waste water pump '9'.
To assemble the valve correctly, consult the waste water pump
manual.
Install hull outlet with valve '11'.
Install the suction hose '17' (38 mm. dia. (1
neither the tank, pump or deck cap are subject to any mechani-
cal loads.
Fit the air-relief nipple '14' as high up as possible above the
level of the top of the tank. Choose a place for the nipple where
rain or other outside water cannot enter.
If required, fit an odour filter '15' between the air-relief pipe and
nipple.

Fit the air-relief pipe '18', internal diameter 19 mm (
between the air-relief nipple and the tank. When viewed from the
tank, the air-relief pipe should run straight upwards.
Install a bend ventilator '10' in the discharge pipe between
pump and hull outlet when the waste water tank is below the
water line and the hull outlet is also below the water line.
Rinsing pipe
In order to rinse out the tank easily with clean water, and extra
fitting can be made in the deck connected to an extra deck cap.
Clean water can be poured in through this pipe.
If the suction connector '3' is not being used, close the suction
pipe off with a plug.
Electrical installation, pump
Make sure that the voltage stamped on the electric motor is
identical as the ship's power supply voltage.
The minimum cross-section for the connecting cables is
2.5 mm
the pump should not exceed 10% of the supply voltage. For a
12 Volt installation with a total cable length (positive and nega-
tive wiring added together) of more than 19 m use cable with a
cross-section of 4 mm
Connect the power supply as shown in the wiring diagram. See
drawing at page 28.
A main switch* and a fuse** must be incorporated in the posi-
tive cable.
*) The switch must be rated for 10 Amps.
**) Fuse:
The electric motor may become hot when used for a longer
period of time! Make sure that electric wiring etc. does not
get in contact with the motor housing.
