Evaporator Fan Motor Assembly The evaporator fan, which is mounted on a bearing supported shaft driven by
an electric motor is designed to pull air through the evaporator coil and discharge it through the opening at the
top of the unit. See Drawing 1325-005 and #207-004.
Receiver The receiver is a cylindrical reservoir of welded steel construction. The tank is equipped with an inlet
and outlet tube and a fusible type plug. Although the receiver is capable of holding the entire charge of
refrigerant in the system, only a part of this refrigerant will be in the receiver at any one time during normal
operation. Liquid refrigerant from the condenser flows through an inlet tube and leaves through the outlet tube.
See Drawing #131-002.
Moisture Liquid Indicator (Sight Gauge) The sight gauge is used to observe liquid refrigerant as it flows through
the system. If the unit contains sufficient refrigerant and is operating normally, the glass will show a full
presence of refrigerant and the sight gauge will display a blue or navy blue color for a dry reading and will
display a purple or orange color for a wet reading. See Drawing #136-002.
