SINGLE POINT REFUELING
Position fueling nozzle (13) near fueling adapter
Install grounding wire plug (15) on receptacle
Install fuel nozzle (13) in adapter (14). Hold
grips (17) tightly and rotate grips and nozzle (13)
clockwise to lock.
Damage to fuel system could result if
refueling hose pressure exceeds 55
If possible, observe the refueling truck
gauges for fuel flow indication.
The system is designed to restrict
fuel flow to 300 gpm during pressure
refueling at a nozzle pressure of 55
Swing flow control lever (18) counterclockwise to
open position. Fuel will start to flow (as indicated
by totalizer (19)) and then stop within 4 seconds.
Valve closing will be indicated by a sudden drop
at the fuel truck flowmeter to near zero. However,
a small amount of fuel will continue to flow
through the open secondary pilot ports. As much
as 15 gallons per minute may flow.
Reset ALL TEST switch (11) to flow, observe
totalizer (19) to verify fuel starts flowing again.
Set ALL TEST switch (11) to SEC OFF. Fuel will
start to flow (as indicated by totalizer (19)) and
then stop within 4 seconds. A small amount
of fuel will continue to flow through the open
primary pilot ports.
If both primary and secondary checks are
successful proceed to refuel aircraft.
