8.2.2 Water Heater
CAUTION
! !
Be certain the water heater is full of water and does
not contain air. If the water heater is not full of wa-
ter, damage to the heating elements may result when
electrical power is turned on to the unit.
The water heater use and function is described in the
Water Systems Section. Here we will detail the electrical
side of the heater.
The water heater is powered by the MDP on the
Navigation Station. It is much the same as an electric
water heater in your home, Consult the manufacturer’s
documentation for any internal information about the
water heater.
When the Water Heater is operating from the Heat
Exchanger, water temperature in the tank will approach
the temperature of the engine coolant.
The Temperature Control Valve (TCV) regulates the flow
of coolant through the Heat
Exchanger by sensing the output temperature of the
water in the tank
