D. SIGHT GLASS / MOISTURE INDICATOR
SIGHT GLASS — Allows viewing of the refrigerant. Bubbles may indicate a shortage of
refrigerant or a restriction in the liquid line. The color indicator shows relative moisture
saturation of the refrigerant. Its inclusion in the refrigerant piping is recommended. A
minimum of 12 hours after installation is required before attempting to determine if a
moisture condition within the system exists.
