9) Check for each pressure of low side and high side if it is within
shaded range of graph.
If each gauge reading is out of specified pressure, correct de-
fective part referring to following Test Diagnosis table.
Example:
Gauges should read as follows when ambient
temperature is 30DC.
Pressure on high pressure
gauge (HI):
Pressure on high pressure
gauge (LO):
NOTE:
Pressure registered on gauge varies with ambient temper-
ature. Therefore, use left graphs when determining if pres-
sures are normal or not.
10) Check inlet port temperature-to-outlet port temperature rela-
tionship using graph.
For example, if evaporator inlet port temperature is 25DC
(77DF) and center duct air outlet temperature is 8DC (46.4DF),
their crossing point is within acceptable range as shown in
graph.
11) If crossing point is out of acceptable range, diagnose trouble
referring to following Performance Diagnosis table.
