Before using any system that requires raw cooling
water, ensure that the intake valve is opened and the
strainers are not clogged. Section 9.4.6 illustrates
the procedure for cleaning your strainers.
9.3.5 Water Heater
The fresh water pump supplies water to the water heater
from the water tanks. A breaker on the AC side of the
MDP, and a rocker switch on the control panel controls
power to the heater.
Follow these procedures when using the water heater:
1. 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
circuit.
2. With the generator running or shore power connected
to your boat, switch on the WATER HEATER circuit
breaker at the AC side of the MDP.
3. Wait for the water in the tank to heat up, then use as
you would at home.
