8) Check inlet port temperature-to-outlet port temperature rela-
tionship using graph at the left.
For example, if evaporator inlet port temperature is 25 C (77 F)
and center duct air outlet temperature is 8 C (46.4 F), their
crossing point is within acceptable range as shown in graph at
the left.
In this case, cooling performance is satisfactory and proper.
9) If crossing point is out of acceptable range, diagnose trouble re-
ferring to following table.
