ELECTRICAL CONSIDERATIONS
WATER COOLED OPTION PACKAGE:
How it works and why
To get absolutely top performance from your
SuperColdMachine, you can add this package at any time
in the future if not with your original installation. If inlet
air temperature to the SuperColdMachine exceeds 90°F,
switching to water cool mode will produce shorter “on”
times and lower average amp draw. As air temperature
increases, the water-cooled advantage increases. In
tropical conditions, the total daily power consumption can
be reduced by 25—40%.
When you select “water pump on” using the switch panel
provided with this option, note that the built-in fan (and
the Powerduct fan, if fitted) continues to run. This ensures
a flow of air over the compressor to keep it relatively cool
and is normal.
It is strongly recommended that you switch the pump off
while using dockside power. With the battery charger
working, it is more important to extend the life of the
water pump than it is to save battery power.
Example: You left the boat on Sunday night, plugged in,
freezer full of food, and left the water pump on. On
Wednesday, a plastic bag gets sucked into the pump
intake. The pump runs dry, its impeller shaft locks up, the
pump motor stalls. The result is a damaged pump bear-
ing requiring replacement (available from WAECO USA).
The “pump / fan” fuse may or may not blow. If it does,
the frozen food may be lost because the unit may shut
down to protect itself. It is important to shut off the pump
when you leave.
