3.1 GENERAL DESCRIPTION
3.1.1 Refrigeration Unit - Front Section
The unit is designed so that the majority of the components are accessible from the front (see Figure 3.1 ). The unit
model number, serial number and parts identification number can be found on the serial plate on the back wall of
the condenser section.
3.1.2 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 used 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 con-
tains 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.
