3. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
a. This is a method in which the trouble is located by using a manifold gauge set. Read the manifold gauge pressure when these conditions are
established.
Test conditions:
-
Temperature at the air inlet with the switch set RECIRC is 30 to 35 degrees C (86 to 95 degrees F)
-
Engine is running at 1,500 rpm
-
Blower speed control switch is at "HI"
