that is moisture sensitive. Dry refrigerant is indicated by the color green, which changes

to chartreuse when the moisture content becomes undesirable, and to yellow when the

level becomes unacceptable . Excessive moisture in the refrigerant may damage or possibly

destroy the compressor. If the liquid refrigerant observed in the sight glass has a milky

appearance, or if frequent bubbles appear, the volume of refrigerant is low and the systemshould be charged. Moisture or low charge indications should be reported to direct support

maintenance for appropriate refrigeration system action.
