WATER SYSTEM
The yacht has 1 water tank with a total capacity of
approx. 315 l. The tank is located amidships under
the galley and saloon floor boards.
The fresh water tank is equipped with an inspection
lid, valves and ventilation.
The pressure water pump (12 V) in the engine room
on the starboard side 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.
NOTICE
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.
Hot Water System – An 40 l 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.
The water can be heated in two ways, either using
the engine or the electric water heater. The first uses
the engine coolant, which is pumped around the
calorifier's integral heat exchanger. Water heats
more quickly when cruising than when moored, this
is due to the extra heat generated when the engines
are put under load.
WARNING
Hot water under pressure is extremely hazardous.
Never attempt any repairs to the calorifier or the
hot water system whilst its contents are hot.
The second way water can be heated is using the
domestic type water immersion heater that is fitted
into the calorifier. The heater is thermostatically
controlled to maintain the water temperature. For
safety reasons, there is a pressure relief valve
mounted on top of the immersion heater that will trip
if the water starts to get too hot.
CAUTION
Do not switch the electric boiler on if there is no
water in the system. Otherwise, the heating
element can be damaged!
The water pump switch can be left in the "on" position when
moored but it is advised that you turn it off when underway.
Water quality - Care must be taken especially in warmer
climates that the water is potable. If the water is suspect the
Skipper/Owner should use a proprietary water treatment
before use.
WATER PUMP PROBLEMS: -
Motor will not start: - Replace upper housing or
motor.
Motor runs but no water: - Replace diaphragm/
jammed check valve.
Low pressure and flow: - Replace pump diaphragm
or motor.
Pump very noisy: - Replace lower housing.
Pump cycles too much: - Replace upper housing.
Pump will not shut off: - (Note not for T60)
Should the water in the fresh water system develop a
slight taint, we recommend the use of water tank
cleaner/deodoriser.
Bleeding the Water System - Should you empty your
water tank completely, you should fill the water tank,
open all the taps and turn on the water pump. As the
water starts to flow cleanly through the taps, turn
them off. Turning off the final tap will shut off the
water pump. Please refer to the OEM literature for
details of maintenance and service procedures.
