You can obtain spare impellers from specialist shops or the dealer. When ordering, always
specify the exact type of the pump.
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.
Empty the system and the tanks if there is a risk of temperatures
below freezing.
Do not switch the electric boiler on if there is no water in the
system. Otherwise, the heating element can be damaged!
1.2.2. Seawater
Seawater is used for two circuits:
•
for the engine system (refer to section 1.7.4)
•
for flushing the toilet
The seacocks 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.
Ensure that the filter lids are proper fastened and that the hose
clamps are proper 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 total capacity of 30 litres is a permanent 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 pump-out deck fitting 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.
Emptying using deck nozzles
The pump-out deck fitting is located on deck and marked “Waste”.
