Operating instructions

Generator Exhausts:
Each generator has an exhaust outlet just above the
waterline midships under the aft spray rail. The 20KW
generator exhausts to port, the 8KW to starboard. You will
want to be careful with generator use when you have
“rafted” Dream Catcher to another boat when anchored!
Stopping a Generator:
1) Switch the Shore Power switch to “Off”. This
removes the load for the generator and allows it
to cool down.
2) After at least a minute of cool down, press and hold the lower stop switch down
(toward the stop sign) until the generator comes to a complete stop.
Generator Problems:
The generators monitor their own operation, a loss in oil pressure or any overheating. If
either occurs, the generator shuts itself off, and will not keep running when you try to restart it.
Before repeated starting, shut off sea water supply to avoid water-
locking the engine! Then, remember to turn it back on when the
generator starts!
4F2: AC Inverter System
The Inverter Makes AC from DC...
As we said, the Inverter system is used to provide
AC to the boat when there is no shore power. It is
wonderful, for example, to use the inverter to make a pot
of coffee when the engine is running and you are
underway, or to watch TV in a quiet anchorage, or use a
hair dryer for a few minutes in the morning. But for long-
period use of AC by large appliances, the engine or
generator must be running or you must have shore power
available.
Now the microwave, for example, will draw about 50 amps of DC when using the
inverter to run it, so in six minutes you use one-tenth of an hour at 50 amps, or five ampere-
hours. That's okay. But what if you want to cook a roast for 30 minutes? You would use up a
lot of energy on that one job alone! That’s too much use for the inverter, and the propane
stove or oven should be used.
For a short task, the inverter is great: no starting the generator, no noise, no fuss, the
power is there. If the engine are running, use it all you wish, as long as you don't try to do two
huge jobs at once: The inverter produces a maximum of 2,500 watts of energy at a time. So
the inverter is only wired to the refrigerator, icemaker, Webasto furnace circulating pump, AC
outlets, and the microwave. It will not run the water heater, battery chargers, washer or dryer.
