Downline pumping assemblies can be damaged if suction pressure falls below
All pumping assemblies can be damaged if discharge pressure rises
above 150 psi.
Suction and discharge pressures will vary depending on operating conditions
and engine speed.
Monitor suction pressure on PUMP SUCTION PRESSURE gauge (10).
discharge pressure on PUMP DISCHARGE PRESSURE gauge (1). If suction
pressure falls below 10 psi or discharge pressure rises above 150 psi,
adjust AUTO THROTTLE rheostat (3) as required.
Refer to step j above.
Perform During PMCS (Table 2-11).
To prevent damage to engine, DO NOT shut down engine suddenly from
Shut down pumping assembly as follows:
Turn AUTO THROTTLE rheostat (3) to START (idle position) .
idle for 2 or 3 minutes.
Set ENGINE switch (2) to STOP.
Set MAIN POWER switch (9) to OFF.
Close control panel door.
Unlock AUTO DEFEAT handle (7) and pull out.
Lock in extended position.
Perform "After" PMCS (Table 1-11).
Refer to Figure 2-26 and perform the following if extended shutdown is
expected or move to a new location is required.
Push air outlet scoop handle (3) to close air outlet scoop (1) and
engine exhaust door (2) .
