Please make sure that the ventilation of the black water tank is
ensured; otherwise the system could be damaged when emptying
the tank.
When pumping out the tank, keep to the following sequence:
•
Open the deck screwing, insert the suction nozzle
•
Suck out/pump out
•
Fasten the deck screwing.
Emptying via seacock
To empty the black water tanks outboard, open the seacocks. Then switch on the pump. After
pumping out, shut the seacocks again.
Please note that there are regulations for certain ports and
shipping routes where it must be ensured that no sewage can be
pumped outboard (e.g. the Baltic Sea Convention). Instruct your
crew and guests how to deal with this.
The toilets and the black water tanks may not be drained near the
coast or in any protected area (see also 3.8)!
In this case, the outboard discharge can be locked and sealed.
Operating the system
Observe the symbols at the toilet to use the WC. Never throw solid or clogging materials or
objects into the toilet.
Maintenance of the system
Never use aggressive liquids, aggressive cleaning agents or deodorants to clean the system
because they may damage the conduit.
Never use pure antifreeze agents when getting the system ready for winter storage. If necessary,
contact your dealer. Always completely empty the system in case temperatures below freezing
are expected.
1.2.4. Bilge system
The anchor locker and the cockpit are self-draining so that no pumps are needed here. The
openings must be kept free of blockages.
The yacht is equipped with a manual and an electrical bilge pump, each with a capacity of at
least 30 l/min. Their functionality is to be regularly checked.
The manual bilge pump is located at the helm position in the cockpit. The electrical bilge pump is
accessible through the floor hatch of the companionway.
The electrical bilge pump can be operated in two modes:
•
Automatically - the pump switches on if the bilge has reached a certain level
•
Manually - the pump is operated manually from the operating panel of the bilge pump.
Please pay attention to whether the valves are open or shut. Take special care to ensure that the
bilge in the engine room is free of oil.
