Refrigerant: Testing and Inspection
REFRIGERANT
ON-VEHICLE INSPECTION
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
a. This is a method in witch the trouble is located by using a manifold gauge set. Read the manifold gauge pressure when the these conditions are
established.
Test conditions:
-
Temperature at the air inlet with the switch set at RECIRC is 30 - 35 °C (86 - 95 °F) Engine running at 1500 rpm
-
Blower speed control switch at "HI" position
-
Temperature control dial at "COOL" position
-
A/C switch ON
-
Fully open doors
1. Normally functioning refrigeration system.
Gauge reading:
Low pressure side: 0.15 -0.25 MPa (1.5 - 2.5 kgf/sq.cm)
High pressure side: 1.37-1.57 MPa (14 - 16 kgf/sq.cm)
2. Moisture present in refrigeration system.
