R (g) Put a container on the access platform below the applicable NACA
R vent in the surge tank.
R (h) On the panel 800VU:
R - put the applicable wing tank REFUEL VALVES switch to the OPEN
R position
R - make sure that the opposite wing tank REFUEL VALVES switch is
R in the SHUT position
R - hold the TEST switch in the HI LVL position.
R (i) Set the fuel tanker to its lowest flow rate and pressure. Let 50l
R (13.2084 USgal) of fuel flow into the vent surge tank. Make sure
R that fuel flows out of the NACA vent.
R (j) On the panel 800VU:
R - put the applicable wing tank REFUEL VALVES switch to the SHUT
R position.
R (k) Stop the operation of the fuel tanker.
R (l) On the panel 800VU:
R - release the TEST switch from the HI LVL position
R - make sure that the applicable HI LVL light comes on
R - put all of the REFUEL VALVES switches to the NORM and guarded
R position
R - put the MODE SELECTOR switch to the OFF and guarded position.
R (5) If the access panel 550BB(650BB) has been removed, do the steps that
R follow:
R (a) Refuel the applicable wing tank fully and keep the fuel tanker
R connected to the aircraft (Ref. TASK 12-11-28-650-003).
R (b) Put a container on the access platform below the applicable water
R drain valve 21QM (22QM). Use the PURGING TOOL (97A28002117002) to
R open the water drain valve (Ref. TASK 28-25-00-650-003).
R (c) On panel 800VU:
R - put the MODE SELECT switch to REFUEL
R - put the applicable wing tank REFUEL VALVES switch to the OPEN
R position
R - put the opposite wing tank REFUEL VALVES switch to the SHUT
R position
R - put the TEST switch to the HI LVL position and hold it there
R - make sure that the applicable HI LVL light goes out.

R (d) Set the fuel tanker to its lowest flow-rate and pressure. Make
R sure that the fuel flows into the vent surge tank and out of the
R water drain valve 21QM (22QM) (Ref. TASK 28-25-00-650-003).
R (e) On panel 800VU:
R - put the applicable wing tank REFUEL VALVES switch to the SHUT
R position
R - make sure that the fuel-flow from the water drain valve
R decreases and stops.
R (f) Close the water drain valve (Ref. TASK 28-25-00-650-003) and
R remove the PURGING TOOL.
R (g) Put a container on the access platform below the applicable NACA
R vent in the surge tank.
R (h) On the panel 800VU:
R - put the applicable wing tank REFUEL VALVES switch to the OPEN
R position
R - make sure that the opposite wing tank REFUEL VALVES switch is
R in the SHUT position
R - hold the TEST switch in the HI LVL position.
R (i) Set the fuel tanker to its lowest flow rate and pressure. Let 100
R l (26.4169 USgal) of fuel flow into the vent surge tank. Make
R sure that fuel flows out of the NACA vent.
R (j) On the panel 800VU:
R - put the applicable wing tank REFUEL VALVES switch to the SHUT
R position.
R (k) Stop the operation of the fuel tanker.
R (l) On the panel 800VU:
R - release the TEST switch from the HI LVL position
R - make sure that the applicable HI LVL light comes on
R - put all of the REFUEL VALVES switches to the NORM and guarded
R position
R - put the MODE SELECT switch to the OFF and guarded position.
R (6) For the access panel 550CB(650CB), refer to (Ref. TASK 28-12-45-400-
