    is illustrated in Diagram 5-13 and 5-14. It consists of controller, explosion-proof motor and co-axis vane pump. The inlet height of submersible pump is 150~250mmm from tank bottom. The motor lead of submersible pump is installed in capacitor box of upper controller. Exterior power supply is connected into junction box of lower controller. After carefully inspection submersible pump and guiding pipe are mounted into 4’�supporting pipe through lower controller, upper and lower part of controller are connected with screws in tank. Diagram 5-12: D421 Junction box wiring 2. Submersible pump wring The wiring of submersible pump is finished in controller, power supply and grounding line integrated in junction box that is sealed by rubber gasket. Connect the two black lines of power supply and controller, grounding line being fixed in junction box. The motor lead, black, brown and blue, respectively, are connected into capacitor box and sealed with ru fuel dispenser bber gasket. To connect the black lead of motor with the black in controller; brown with one of pins of capacitor, blue lead with the other terminal of capacitor after connecting with another black lead.

Fuel dispenser debugging 3.1 It is absolutely prohibited to debug fuel dispenser using water rather than oil or fuel. Debugging procedure of fuel dispenser A universal inspection should be conducted before first debugging of fuel dispenser, eliminating various elements that affect operation, lead connection in particular. Computer display screen and presetting display should be carefully examined as switching on power, lighter in electric box also being check. Starting up suction pump and open nozzle, carefully examine all connection and sealed jointer face in case of leakage and penetration. Confirming each nozzle is corresponded to its produ fuel dispenser

    al; groundwork for the begathon has already begun. Robin Cleveland, an adviser to the bank s president and, like him, a veteran of the Pentagon, is leading its effort to drum up “good stories�about the bang it gets for its billions. The aim is to help her boss on his Pauline mission to evangelise the doubting chancelleries of Europe and beyond. There are signs the institution is reassuring some sceptics. Last month, it survived a “mid-term review� of its work in the 18 months since the last round of donations were agreed in April 2005. This week, it got a vote of confidence from Britain and Sweden. Both countries had pledged an extra slug of money� respectively £50m ($99m) and SKr250m ($37m)—in the last funding round, but only on certain terms. The British want the bank to stop putting its financial muscle behind economic reforms, such as privatisation or trade liberalisation, in countries that do not really want them. This week both donors said fuel dispenser they had seen enough progress to release the money—although Britain added that the issues close to its heart would remain “a central consideration�in the replenishment talks next year. The bank will feel encouraged. It also expects to benefit from the fresh enthusiasm for aid fuel dispenser stirred up last year in the run-up to the Group of Eight summit in Gleneagles. In a recent issue of Time magazine s Europe edition Mr Wolfowitz paid extravagant tribute to Bono and Bob Geldof, two “peerless�aid campaigners. But the bank faces stiffer competition for aid dollars than ever before. There are over 150 multilateral bodies—from the African Development Bank to the United Nations Children s Fund—and a gaggle of funds, facilities and initiatives dedicated to specific causes, such as the President s Malaria Initiative (see article), launched by George Bush. World Bankers insist that a big, all-purpose aid pot is well worth having—and expanding. The problems of development grow in dense thickets, they argue; one thing is tangled up with fuel dispenser
