System Normal

Normal Gauge Readings:

Read manifold gauge pressure with the following established conditions:

1. Air inlet temperature 86° - 95°F (30° - 35°C).
2. Engine running at 2000 rpm.
3. Blower speed set at high.
4. Temperature control set at cool.

NORMAL SYSTEM PRESSURES

Low Pressure Side
21 - 28 psi (147 - 196 kPa)

High Pressure Side
206 - 213 psi (1422 - 1471 kPa)

NOTE: Gauge readings may vary slightly due to ambient temperature conditions.
