4-16 Fuel Transfers-Cont'd.
e.
Transfer Fuel from Switching Manifold to Primary Module Tanks
This can readily be done if a full tank inventory is desired in the fuel unit. Normal practice is to transfer to the secondary
module tanks first to allow BS&W to settle out before dispensing.
1.
Reset meter ms1j to zero or record reading.
2.
Open valves in the hose line route to tank.
a)
To TSJ. Open VIJ, V2J, V16J. V17J, V36J, V37J, and V39J.
b)
ToT6J. Open VJ, VJ, V16J, V17J, V36J, V37J, andV47J.
3.
Transfers may be made to both primary tanks simultaneously if desired, however, the quantity to a specific tank
will not be recorded by meter.
4.
If transferring to two tanks simultaneously, the flow to each tank will not necessarily be equal. Close the valves
to a particular tank when the tank top touched the range pole cord.
5.
If transferring to a single tank and a continuing transfer to the other tank is desired, first open the valves in the
route to the second tank and then dose the valve in the route to the full tank. Record the meter reading at the time of the
shift. This can be used to determine the quantity transferred to the first tank.
6.
When the transfer is complete to all tanks, close valve V1J and record the meter reading.
7. Close all valves opened in the transfer process
f. Transfer Fuel from a Secondary Module Tank to a Primary Module Tank
This operating instruction specifically covers the transfer of fuel from secondary module tank T1J to primary module tank
T5J. Procedures used to transfer from any secondary module tank to either primary module tank are the same except
through a different route and different valves which can readily be determined by study of the P&ID flow diagram, Fig. 4-
1.
1.
Observe and record range pole reading of tanks TIJ and TSJ.
2.
Open valves V6J, V7J, V 1J, Vt2J, V 4J, V18J, V36J, V37J. and V39J.
3.
Start and operate pump P3J taking suction on T J and discharging to tank TSJ.
4.
Observe closely the process of transfer and the positions of the tank tops in relation to the range pole cord.
5.
Shut down pump PIJ when either one of the following occurs
a)
Top of tank T5J touches the range pole cord.
b)
Tank T1J goes near flat (say 6 inches) and is obviously nearly empty.
