Low Oil Guard
To help prevent catastrophic damage, FS Curtis provides an option for a Low Oil Guard, which
shuts the unit down when the oil level has dropped below the low oil mark on the sight glass or
dipstick, see Fig (12) for proper oil level. FS Curtis’s low oil guard utilizes a magnetic float
switch
CAUTION!
A low oil guard is not a substitution for proper maintenance. Continue to perform
regular oil changes at intervals stated in this manual.
WARNING!
Never assume a compressor is safe to work on just because it is not currently
operating. It could restart at any time. Follow all safety precautions outlined in the
Safety Precautions section. Turn off and lockout/tagout the main power disconnect
switch before attempting to perform maintenance on the unit.
