Sight Glass: Description and Operation
REFRIGERANT SYSTEM SIGHT GLASS
The refrigerant system sight glass is located on the top of the filter-drier. The sight glass is provided as a diagnostic tool, which allows visual
observation of the refrigerant flow. The sight glass also serves as a refrigerant level indicator.
The refrigerant system sight glass cannot be repaired, and is only serviced as part of the filter-drier unit. If the sight glass is faulty or damaged, the
filter-drier unit must be replaced.
