Fresh Water System
The boat standard features include three 230 l tanks. To prevent any handling mistake, never fill the
water and fuel tanks at the same time. One front filling cap allows the tanks to be filled up (see deck
plan). During filling, avoid handling contaminants near the fillers. Open and close the filler caps with
the right key. Check the filler cap seals for condition during filling. Never insert the water filling hose
deep down into the system in order to prevent any over-pressure in the systems.
The sinks, showers and washdown system are fed with fresh water by an electric pump. A filter is
installed in the pump circuit, it must be cleaned regularly.
The water pump is located under the small hatch in dinette under the fly central glass. (see fresh
water plan). Its starting is done by using a switch on the electrical panel.
Never run the pump if the tank is empty. Fill up the tank before reusing the circuit.
It is possible to sterilize tanks with clonazone lozenge (available in pharmacies). Every year,
dismantle the trap doors to clean them by filling with water containing a bactericidal detergent, let
the product act a few hours and then do 2 to 3 rinses. In winter, fill the tanks thoroughly to avoid the
proliferation of algae or bacteria, or empty the tanks if there is a risk of freezing, never use antifreeze.
The production of hot water is provided by a water heater connected to the engine cooling circuit
and the shore power socket. After draining the water heater, make sure the resistor is immersed
before turning on the power again.
