3.1.3 Evaporator Section
The evaporator section ( Figure 3.2 ) contains the return temperature sensor, humidity sensor, electronic expansion
valve, dual speed evaporator fans (EM1 and EM2), evaporator coil and heaters, defrost temperature sensor, heat
termination thermostat and evaporator temperature sensors (ETS1 and ETS2).
The evaporator fans circulate air through the container by pulling it in the top of the unit, directing it through the
evaporator coil, where it is heated or cooled, and discharging it at the bottom.
Most evaporator components are accessible by removing the upper rear panel (as shown in the illustration) or by
removing the evaporator fan access panels (see
Figure 3.1 , Items 1 and 16).
