Water Systems
9.5
Follow these procedures when using the water heater:
Make sure the water heater is full of water. Open a
hot water faucet and allow a steady stream of water
to flow out of the faucet to remove all air from the hot
water system.
With shore power connected to your boat, or the
optional generator running, switch on the water
heater circuit breaker.
Wait for the water in the tank to heat up, then use as
you would at home.
WARNING
! !
IMPORTANT!
Water temperatures in excess 110ºF (43ºC) are
dangerous and may cause scalding, severe injury or
death
9.4.1 Water Heater Temperature Adjustment
(Thermostatic Mixing Valve)
Let the water flow for at least 2 minutes to allow sup-
ply temperature to stabilize.
Calibrate the mixed water outlet temperature by plac-
ing a thermometer in the mixed water stream.
To adjust the setting of the valve, loosen locking cap
with hex wrench (Fig. 9.17). Cap must be lifted 1/4”
to adjust temperature.
To increase the temperature, turn counterclockwise.
To decrease temperature, turn clockwise.
Lower handle and tighten screw.
Check outlet temperature (compare to the scalding
temperature reference table listed below).
NOTE: Consult the water heater manufacturer’s OEM manual
for further details regarding operation, care and maintenance.

CAUTION
! !
Always ensure engine and air conditioner intake
valves, or seacocks, are open before using these
components. Failure to do so could overheat and
cause them significant damage.
9.3.6 Toilet Water Supply
The manual toilet uses raw water for flushing. The
optional electric toilet uses fresh water from the fresh
water system (salt water can damage the electric head
components). Please refer to Figure 9.17 for the raw
water layout for the manual toilet.
For further information on the head system, please refer
to the Waste Systems chapter in this manual.
9.4 Water Heater
The fresh water pump supplies water from the water
tank to the water heater (and cold water lines). The
water heater is located in the main salon port aft settee
and accessed through the storage compartment lid (Fig.
9.10).
The water heater breaker switch is on the AC panel.
When the breaker is turned ON, the water heater will heat
water until the established temperature level is reached.
Before switching the breaker ON, ensure the fresh water
pump breaker switch on the DC panel is also ON and the
system is pressurized.
