5.2 Freshwater System Operation
Fill the water supply tank slowly through the labeled deck plate. After filling
the water tank, partially open all faucets. The water pressure breaker on the
cabin DC panel should be on. Allow the pump to run until all of the air is
purged from the system and a steady stream of water is flowing from each
outlet. Next, turn off the faucets one by one. As the pressure builds, the pump
will automatically shut off.
When properly primed and activated, the water system will operate much like
the water system in a home. An automatic pressure sensor keeps the system
pressurized. If the system has been recently filled or has not been used for
an extended period, air bubbles may accumulate at the pump and the system
may have to be reprimed.
The galley and head sinks drains into a sump system where the water is pumped overboard. Always
make sure the shower/cabin drain sump pump is activated before using the sinks. Refer to chapter
7 for more information on the drain sump system.
Whenever the boat is left unattended, the water pressure breaker should be placed in the “OFF”
position.
DO NOT ALLOW THE FRESHWATER PUMP TO RUN DRY. THE FRESHWATER PUMP
WORKS ON DEMAND AND WILL NOT SHUT OFF AUTOMATICALLY WHEN THE TANK
IS EMPTY. THIS CAN RESULT IN DAMAGE TO THE PUMP. ALWAYS TURN THE WA-
TER PRESSURE BREAKER OFF WHEN THE FRESHWATER SYSTEM IS NOT IN USE.
5.3 Water heater (Optional)
The water heater is located in the bilge. All heaters have a 110-volt element that is thermostatically
controlled at the heater and activated by a circuit breaker located in the 110-volt panel. A high
pressure relief valve protects the system from excessive pressure. Always make sure all air is
purged from the water heater and lines before activating the water heater breaker. Refer to the water
heater owner’s manual for additional information.
DO NOT SUPPLY CURRENT TO AN EMPTY WATER HEATER. DAMAGE TO THE HEATER
WILL RESULT. THE SYSTEM MUST BE FILLED AND PRIMED BEFORE USING THE WA-
TER HEATER.
