416 Fuel Transfers- Contd.
operations below are based on pumping tank T1J to the dispensing assembly. The route from other tanks can readily be
understood by study of the P&ID flow diagram, Fig. 41.
1.
Open valves V6J. V7J, VI 11, V12J VV14J, V18, V36J. V37J, V38J, V461. V54J. V55J.
V56J
V59J. Open V60J and V61J if the 1-inch and -n1/2-inch loading spots are to be used.
2.
Connect the dispensing coupling (or couplings) to the tanker truck(s) being loaded.
3.
Start pump P J and hold at a very low discharge pressure or in the idle position.
4.
Open valves leading to the appropriate dispensing coupling or couplings in use.
5.
Raise P1J discharge rate to that required for the dispensing assembly load. Adjust rates to follow changes in the
dispensing set load.
6.
If filling user vehicles the dispensing nozzles V66a-fJ are used at the will of the refueling operator.
7.
When loading is complete, dose the valve nearest the coupling. Disconnect the coupling.
8.
When any particular dispensing line is not going to be in service for any extended period that the block valves
V62a-fJ and V64a, bJ should be left closed.
9.
The above instructions pass fuel through the filter separator FS1J. If FS2J is to be in service in lieu of FS 1J,
open valves V57J and V5sJ. Close VSSJ and V56J. If for some reason it is desired to have both filter separators in
service, leave VSSJ, V56J, V57J and V58J open.
10.
When no fuel is being drawn from the dispensing assembly, shut down the pump in service.
11.
When fueling operations are complete or are to be secured for an extended period, close all valves.
WARNING
DISPENSING SET PRESSURE
Keep dispensing assembly pressure as low as possible and still maintain the required rates of
dispensing. High pressures can result in hose whip, splash back, and spills.
WARNING
GROUNDING
Make sure grounding system at dispensing assembly is in good condition and utilized. Stop loading if
any static electricity discharge takes place until the cause is found and corrected.
