2.1.3 Evaporator Section
The evaporator section (Figure 2-2) contains the
temperature recorder bulb or return recorder sensor,
return temperature sensor, thermostatic expansion
valve, dual-speed evaporator fans (EM1 and EM2),
evaporator coil and heater, drain pan heater, defrost
heaters, defrost temperature sensor, heat termination
thermostat, and heat exchanger.
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.
The evaporator components are accessible by
removing the upper rear panel (as shown in the
illustration) or by removing the front access panels.
