2. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
a. This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when the following conditions are
established:
-
Temperature at the air inlet is 30 to 35 degree C (86 to 95 degree F).
-
Engine is running at 1,500 rpm.
-
All doors are fully open.
-
Blower switch is at HI.
-
Temperature control switch is at MAX. COOL.
-
A/C switch is ON.
1. If the refrigeration system is functioning normally, the gauge readings are as shown in the table.
