Refrigerant System With Manifold Gauge Set

INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
This is a method in which the trouble is located by using a manifold gauge set.

Manifold Gauge Installation/Removal

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 1,5OO rpm
- Blower speed control switch set at high
- Temperature control set at max. cool
