REFRIGERANT SYSTEM INSPECTION WITH MANIFOLD GAUGE SET
This is a method in which the trouble is located by using a manifold gauge set.
(See "USE OF MANIFOLD GAUGE SET" on page AC–21)
Read the manifold gauge pressure when the following conditions are established:
(a) Temperature at the air inlet with the switch set at RECIRC is 30 – 35 _C (86 – 95 _F)
(b) Engine running at 1,500 rpm
(c) Blower speed control switch set at high
(d) Temperature control set at max. cool
HINT: It should be noted that the gauge indications may vary slightly due to ambient temperature
conditions.
1. NORMALLY FUNCTIONING REFRIGERATION SYSTEM
Gauge reading:
Low pressure side:
0.15 – 0.25 MPa (1.5 – 2.5 kgf/cm')
High pressure side:
1.37 – 1.57 MPa (14 – 16 kgf/emt)
