Preparation For Winter - Vetus WWS42 B Serie Instrucciones De Instalación Y Manual De Operación

Preparation for winter

The tank, pipes, pump, etc., should always be drained.
Never add anti-freeze to the tank or other parts of the waste
water system to protect against frost damage. Anti-freeze is
very poisonous!
Propylene-based anti-freeze may be used.
Clean the tank according to the cleaning procedure.
Maintenance
Regularly check the air-relief nipple (14) and clean its sieve if
necessary.
Regularly check the hoses and hose connections for possible
leaks and fit new hoses and/or hose clips when necessary.
Also check the tank for damage caused by abrasion. Replace a
damaged tank immediately.
At the end of the cruising season, carry out the cleaning and
sterilizing procedures as described under 'Use'.
A tank and installation which is seriously polluted with algae can
be cleaned by thoroughly rinsing out the tank, pump and pipes
with chlorine.
Clean the valves if necessary. Thereto remove the relevant hose
pillar, remove the valve and clean it. Re-assemble in reverse
order.
Ensure that the valves are refitted in the correct manner.

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
ventilated.
• There must be sufficient free space available to perform
maintenance on the pump.
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 (
from bulkheads or other tanks, to provide ventilation.
Make sure that the founda-
tion for the tank is strong
enough to locate it secure-
ly. The tank will increase
in size slightly when filled.
Take this into account
when securing the tank.
Attach the tank using the
stainless steel rings sup-
plied.
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 addi-
tional holes on the top of
the tank for extra fittings
(43 mm (1 11 / ") dia.).
16
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.
