a.
Close the discharge hose unisex coupling valve at the D-1 inlet.
b.
Close open/close actuator.
c.
Drain the D-1 nozzle IAW local SOP.
d.
Disconnect D-1 nozzle and install dust caps.
e.
Connect the CCR nozzle to the discharge hose unisex coupling valve and resume fueling operation.
19. To change from use of a CCR or D-1 nozzle to the open port nozzle during refueling operations:
a.
Close the discharge hose unisex coupling valve at the CCR/D-1 inlet.
b.
Drain the CCR/D-1 nozzle IAW local SOP.
c.
Disconnect the CCR/D-1 nozzle and install dust caps.
d.

20. Remove condensation from fuel lines.
NOTE
Perform the following procedure to remove condensation from a flooded system that has been
unused for an extended period (e.g., overnight) during which the temperature has decreased
significantly.
a.
Close unisex coupling (figure 10, 15) on liquid fuel filter-separator (14) outlet valve.
CAUTION
Never subject nozzles to auxiliary pump suction. Seals will rupture.
Drain nozzle immediately after disconnecting it from system. Trapped fuel can
cause large internal pressure that can damage the nozzle when the temperature
rises.
b.
Close discharge unisex coupling valves (12) and disconnect and drain all nozzles (13).
c.
Select a fuel drum (figure 11, 2) to defuel into.
d.
At selected fuel drum (2), close inlet elbow valve (3) and unisex coupling valve on discharge hose (4), disconnect
discharge hose (4) from inlet elbow valve (3), connect the discharge hose (4) to the flow side (5) of auxiliary pump
(1), and open unisex coupling valves on flow side (5) of auxiliary pump and discharge hose (4).
