The water heater is located in the starboard side of
the engine room. It operates on the 120 volt (or
220 volt) dockside system or generator and has a
circuit breaker on the AC main distribution panel
located in the salon.
The water heater has a check valve to prevent hot
water from back-washing into the cold water source
and a pressure relief valve to avoid damage to the
heater from over pressure of excessive
temperature.
The hot water exchanger is designed to heat water
without having to turn the hot water heater on. It
works by pumping water from the engine cooling
system, out the intake manifold to the hot water
heater. It is then circulated through a coil inside
the water heater where it heats the potable water.
The water from the engine then exits the water
heater and returns to the engine through the engine
water pump.

HOWER
S
YSTEM
The shower drains into a self-contained shower
sump containing a pump and float switch.
NOTE:
Air conditioner condensation also drains into
the shower sump.
The sump pump is fully automatic and is protected
by a breaker on the main DC distribution panel
(see Supplemental Information for the location in
your boat). Check the pump and float switch for
obstructions and proper working order.
The pump comes on when there is enough water
in the sump to raise the float switch and start the
pump. If it does not come on after one or two gallons
of water drain from the shower, turn the water off
and check the pump and float switch for proper
operation.
After using the shower, it is recommended that you
run a gallon of clean water through the shower drain
to clean out soap residue. Check the pump and float
switch for obstructions and proper working order.
