•
When your boat is to be left unattended for long
periods of time, pump the water tank dry to prevent
stored water from becoming stagnant and distaste-
ful. Should it become necessary to disinfect the
freshwater system, ask your dealer about treatments
available for your yacht’s system.
•
The water filter, located under the floor cutout in the
aft berth, should be inspected and cleaned often.
•
The water tank is located in the aft berth, under the
inboard mattress.
Water Heater
•
Your yacht is equipped with a water heater. The water
heater is located in the utility room.
•
The water heater is connected to the AC power system,
therefore, you must verify that the water heater breaker
on the AC panel is turned ON before water will be heated.
•
There is a heat exchanger system connected to the port
engine. All hoses related to this system should be checked
frequently for proper condition, and leakage.
•
Be sure to read the manufacturer’s instruction manual
supplied in your yacht’s owner’s packet and observe the
following warnings:
Fresh Water System Winterization
To reduce the possibility of system damage due to extreme
weather (such as freezing), freshwater systems that have a city
water inlet installed should be winterized as follows:
Water Heater Pressure Relief Valve/Overboard
Discharge Hose Winterization:
1. Disconnect the pressure relief overboard
discharge hose from the water heater.
a. If no water is present in the hose, proceed to step two (2).
b. If water is present in the hose, the water heater pressure
relief valve is not working properly and will need to be
replaced. After replacing the pressure relief valve, empty
all of the water from the hose before storing your yacht.
2. Reconnect the hose to the water heater.

to scald the skin.
WARN I NG!
!
WATER HEATER DAMAGE HAZARDS! DO NOT energize the AC water heater electrical
circuit until the heater is completely filled with water. Even momentary operation in a dry tank
will damage the heating elements. Warranty replacements will not be made on elements or tank
damaged in this manner. The tank is full if water flows from the tap when the hot water is
turned on in the galley.
The water heater should be drained and the power turned OFF when the possibility of freez-
ing exists.
