Note: If air bubbles come from a water tap, immediately switch off
the corresponding pressure water pump at the distribution fuse panel.
The pumps are safe to run dry for a short period of time. When
running dry for a longer period of time, the pump’s impeller may be
damaged.
You can obtain spare impellers from specialist shops or the trader. When ordering, always specify
the exact type of the pump.
Attention! If drinking water is stored for a longer period of time,
disease-causing bacteria can develop. Use appropriate and approved
agents to protect against bacteria. Change the water frequently and
rinse the tank.
An electric boiler is installed to make hot water. The cold fresh water is supplied via the pressure
pump. Due to the pressure drop in the cold water system when filling the boiler, the pressure
water pump automatically switches on.
Note: Empty the system and the tanks if there is a risk of
temperatures below freezing.
1.2.2. Seawater
Seawater is used for two circuits:
for the engine system (see Section)
for flushing the toilet
Attention! The seawater valves must be shut after use!
Clean seawater free of impurities is necessary for the faultless operation of the systems. Therefore,
check the seawater filter on a regular basis, and clean or replace the filter pads if necessary.
Danger! Ensure that the filter lids are firmly fastened and that the
hose clamps are firmly fixed, otherwise there is a risk of water
penetration.
1.2.3. Black water
Black water designates all sewage from the toilets. Seawater is used for flushing. It is pressed into
the bowl and pumped into the black water tank with the contents of the bowl.
The black water tank with a capacity of 30 litres is a firmly installed tank in the immediate vicinity
of the toilet. The tank’s ventilation ends in the boat’s side.
The tank is emptied either via the respective deck suction nozzle with the help of a suction plant
on shore or outboard via the seacock. Please check whether the hoses are compatible with the use
of chemicals.
Before leaving the port, make use of the available pumping facilities to empty the black water tank
in any case.
