BG 2000 OPERATION
The SEA FROST BG 2000 system is an electrically driven refrigeration plant. Operation
of the compressor will freeze the contents of the holdover devices in the boat's icebox
providing refrigeration by cold holdover for an extended period after the compressor has
been turned off. A boat without continuous power can benefit from this by operating the
SEA FROST BG 2000 system when the generator plant is operated. Operation time will
vary with each boat.
A little time-spent learning about your system and some experimentation will be best.
Maximum holdover will be reached when the cabinet is at the desired temperature and
the holdover plates are frozen. Running times beyond this have no advantage other
than to delay warming the plates.
The system is water-cooled. Water should begin to flow from the discharge at the same
time the unit starts. Be sure the water is flowing. If no water flows, stop the system and
inspect the water pump and strainer for obstructions. (See "Troubleshooting" and
"Maintenance" sections.)
After starting a warm system check the plates for a temperature drop. If a temperature
drop is not indicated, stop the unit and read; "Checking The Charge", and; "Reading
The Sight Glass".
CONTROLS
The BG 2000 thermostat control is labeled with "off", one, two, and three snowflakes.
When the boat’s breaker panel is switched on and AC power is available, turning the
knob from "off" to one snowflake will start the compressor. Turning the knob to three
snowflakes will increase the time the compressor operates, making the temperature
cooler. Experiment with the control position to obtain the best setting.
