Air Flow - Model 501F (Figure 3-2)
The cold air travels up the back channel and across
the evaporator coil.
The cold air then discharges at the top of the cabi-
net and is pulled downward in all directions
around the storage shelves, maintaining even shelf
storage temperatures.

NOTE: Figure 3-2 shows air flow for units manu-
factured after S/N M663116/P679466 with black
fan blade, part no. 3-15-045-0. Units built prior
to these serial numbers use a white fan blade, part
no. 3-15-006-0, and the air flow is opposite than
that shown. Starting with S/N M/P1004775, fan
blade is grey, part no. 3150520.
