There are three conditions of charge indicated by the sight glass:
1. A black or clear glass and no cooling indicates no charge. Turn off the
compressor at once.
2. A white foaming glass and some cooling indicates the system is undercharged or
has lost charge. Refer to the manual regarding leak checking and adding
charge.
3. A black glass and proper cooling indicates all is well.

Feel the SEA FROST Plate in the icebox ten minutes after engaging the timer switch. If
the sight glass clears yet the plate temperature does not drop after 10 minutes of
operation, turn off the system and CALL US AT 603-868-5720.
Inspecting the sight glass periodically for several weeks after a new installation and
every time after a lay period is assurance that your SEA FROST DC 5000 system is
assembled properly and is a good maintenance habit as well.
