TROUBLESHOOTING
The most common problems that can occur in a SEA FROST BG 2000 System are:
(1)Overcharge or loss of water flow switching off the manual reset
(2)Loss of refrigerant charge resulting from leaks.
(3)Moisture or dirt plugging the expansion valve.
(4)Compressor damage due to loss of refrigerant charge.
STEP 1. Gather information as to the nature of the problem before operating the system. A leak often leaves a trace of oil. Inspect the fittings and tubing for wear, corrosion, and chafe. Do not operate the compressor until the trouble is corrected.

When water flows from the connection retighten the connection.
*This switch will disconnect if the water flow stops.
*This switch will disconnect if the system is overcharged.
Overcharge may not appear until the boat moves into warmer water than it has been commissioned in. Discharge the system until the unit operates without activating the
For further troubleshooting, attach purged gauges at the compressor.
