2.1 GENERAL DESCRIPTION
2.1.1 Refrigeration Unit
− Front Section
The unit is designed so that the majority of the
components are accessible from the front (see
Figure 2-1). The unit model number, serial number, and
parts identification number can be found on the serial
plate to the left of the compressor.
2.1.2 Fresh Air Makeup Vent
The function of the upper or lower makeup air vent is to
provide ventilation for commodities that require fresh air
circulation. A manually operated venting system is
located in the upper left access panel.
The optional eAutoFresh vent system is to moderate the
atmospheric level in the container in response to cargo
respiration. When transporting frozen cargo loads the
vent will be closed. The upper left access panel contains
the vent slide and motor assembly. It may be removed to
allow entry into the evaporator section where the CO
2
sensor and drive pack are located.
