This Item Features: - This and all of the sight glasses should be located as close as normal, the refrigerant fluid appears perfectly liquid underneath the "lens" of the indicator. The presence of bubbles indicates that the refrigerant fluid is partial evaporating along the liquid line. - The sight glass will show bubbles if the system is low on refrigerant. The sight glass may show a few bubbles when the system first starts. Or, they may appear just as the system stops. - These are normal equalizing actions and do not indicate a shortage of refrigerant. Bubbles may also show a restriction in the circuit ahead of the sight glass. This may be due to a partially clogged drier, screen, or filter. - The sight glass has long extensions that permit soldering or brazing the joints without injury to the sight glass. Some sight glasses are built into a suction line or liquid line filter-drier. - Sight glasses also incorporate a visual moisture indicator which changes color if moisture rises to an unacceptably high level. The moisture/liquid indicators consist of a sensitive element as a ring, which changes color in the presence of water. The amount of change indicates the amount of water present.
