OPERATING INSTRUCTIONS Operation & Maintenance Manual
If there is no air demand at idle speed (pressure rises above the unload point pressure), the
compressor will unload by closing the inlet valve. The compressor then r uns at idle speed
unloaded with
no air delivery. If air demand increases (pressure falls below the load point
pressure), the compressor reloads to meet the required air demand.
Shutdown
1. Close all Service Valves.
2. Allow the en
gine to idle for 3 minutes to cool down.
3. Turn Key Switch off.
Since the
service valve is closed, air downstream of the valve may be
trapped. A vent hole in the service valve will slowly bleed air from the
hose. Do not disconnect hoses until all pressure has been vented.
Do NOT wire around or bypass a shutdown sensor or switch.
