4-15 Commissioning - Cont'd.
4.
Transfer fuels to the modules selected by operating management if desired. Use procedures in para. 4-16
through 4-16.5p.
5.
Record the inventory.
4-16 Fuel Transfers
4-16.1 The operating instructions below are referenced to the equipment and valve identification numbers shown on the
P&ID flow diagram, Fig. 4-1. The instructions are based on the jet fuel unit but apply to the mogas and diesel fuel units
as well. The valve and equipment numbers are the same in each fuel unit except for the service designation J, D, or M.
Valve V1J, for example, has the same function as V1D or V1M.
4-16.2 These instructions assume that the commissioning procedures outlined in para. 4-15 through 4-15i. 5 have been
undertaken and that excessive air and thus excessive venting at the tanks will not take place.
4-16.3 Feed rates to the fuel unit are assumed to be not in excess of 800 gpm. Entry pressure, that is, pressure at the
switching manifold is assumed to be not in excess of 150 psig as specified. Pump discharge pressures to the dispensing
sets must not exceed 75 psig.
4-16.4 It is recommended that all the safe working and operating practices noted in prior sections, and particularly in
para. 's 4-7 through 4-7. 2, be reviewed again. It is also recommended that the instructions on the operation of major
equipment described in the applicable specific technical manuals be reviewed again and considered part of these
instructions.
WARNING
OVERFILLING FABRIC TANKS
Do not overfill the fabric collapsible tanks. A spill through the vent or possibly a rupture and major spill could result.
CAUTION
CLOSE VALVES AFTER TRANSFER
To avoid future operating error, close all valves after each transfer operation.
4-16.5 Specific fuel transfer instructions are as follows:
CAUTION
PRESSURE BLOCKING IN
When a fuel transfer is completed it is generally recommended that the valve in the applicable line of flow that is furthest
upstream (closest to the source of pressure) be closed first and sequentially followed by the closure of the valves next
downstream. This will avoid the blocking in of fuel under pressure an thus enhance the safety of the system.
