Read the operating and maintenance instructions for your boat’s bilge pump carefully.
ATTENTION!
The level of the water in the bilge must be kept to a minimum.
WARNING
The bilge pump system is not designed to handle water entering as a result of holing of
the hull. It is intended to remove water coming from spray, leaks from seacocks or other
moderate leaks.
ATTENTION!
● Ensure that the bilge pumps are working before taking to sea.
● Regularly clean the sump and the points or suction strainers of the pumps of any remains
which could block them.
If the watertight bulkheads that isolate the fore- and after-peaks are fitted with valves, they
should normally be kept closed and should be opened only in order to drain the water into
the main bilge.
● identify each hand pump and its lever.
● Locate the switch for the electric bilge pumps on the electric control panel.
Pressurized fresh-water pump
Fresh water is supplied to the sink and washbasins by an electric pump. A filter is installed upstream of
the pump, it must be cleaned regularly.
Never allow the pump to run if the tank is empty. Refill the tank before using the water supply
again.
The tanks can be sterilized using Clonazone® tablets (available from pharmacies). Every year, remove
the inspection covers and clean them by filling with water containing a bactericidal detergent; leave it
to act for a few hours, then rinse two or three times. During wintering, fill the tanks up completely to
avoid the development of algae or bacteria, or if there is a risk of freezing, empty the tanks; never use
anti-freeze.
Hot water is produced by a water-heater connected to the engine cooling circuit and the shore electric
supply.
After the water-heater has been emptied, make sure that the element is covered before power is re-
applied.
