The yacht has 1 water tanks with a total capacity of approx. 210 l.
The filler neck for the freshwater tank is located in the anchor locker.
Before filling, check whether the marking on the filler neck is correct.
The pressure water pump (12 V) in the forward cabin draws the water from the tank and feeds
cold water to the taps. When taps are opened, the pump is activated. When they are shut, the
pump is switched off by the counter-pressure.
Should the pump continue to run, the system must be checked for leakage.
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 may be
damaged.
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 complete system, the electric boiler 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!
Switch off the fresh water pump and open the hot water faucet to relieve pressure in water
system while driving with the motor. This will alleviate pressure build up in the boiler and prevent
the relief valve in the boiler from opening up.
