Both pressure gauges of the Pres-sure
Test Gauge Manifold, Tool - ACL53-3,
will read neutral sys-tem pressure
(approximately 50 - 75 P.S.I. at an
outside air temperature of approximately
70
0
- 75
0
.) See figure 11.
If the gauge readings are below normal,
or there is no pressure indicated, attach
center hose of the Pressure Test Gauge
Manifold, Tool - ACL53-3, to the Freon
tank and turn low pressure gauge valve
counterclockwise until open. Open
