layers of oil resistance and erosive resistance. Single thread and aluminum wire are prohibited. Diagram 5-7: Wiring in TN-S Power supply system The connection between fuel dispenser and distributing room adopts bushing-pipe burry, preventing vehicle crush wires. The wire pipe installed at bottom of fuel dispenser should have downward elbow in case oil pouring into fuel dispenser and erode wire. No jointer is set between the pipeline of junction box and wire outlet, in case of sparkle jeopardy. User’s wire should correspond to earthing line and po fuel dispenser wer lines after importing exploision-proof junction box. Tighten nut and clamp wires ensuring the explosion-proof performance. Change one of three wires if motor does not work. If adopting TN-S power supply system, wiring from switchboard are connected as diagram 5-7 illustration. If adopting TN-C-S OR TN-C system, wiring as Diagram 5-8. Grounding of fuel dispenser is in well condition. It is to adopt brass wire with PVC insulting bushing as communicating line between fuel dispensers. Communicating line is buried in galvanized pipe. Diagram 5-8: Wiring in TN-C-S or TN-C Power supply system Fuel dispenser should set single earthing line, with resistance no more than 4Ωto earth, 10 Ωnozzle to earth. User’s wire should adopt copper line with no less than 6mm2 section in single phase motor. Otherwise, there is something wrong with motor, even resulting in electric trouble. Diagram 5-9: Wiring Diagram of Communicating Box Ar fuel dispenser ticle II Submersible pump type dispenser and its installation Compared with fuel dispense mounted suction pump, submersible pump fuel dispenser has many merits such as low noise, stable operation, cost-efficient pipeline, and is installed in large station, which is the development direction of fuel dispenser industry. Submersible pump fuel dispenser consists of main frame, submersible pump and electric control box, which are communicated through electric and signal cable. See Diagram 5-10.

out to be arrested. But senior PP figures have openly fanned conspiracy theories that still try to establish some link between the Islamists and ETA. The noise over the March 2004 bombings drowns out the PP s more centrist message. Strategists want hard-core voters to stay loyal; they fret that a new far-right party may emerge. The warm and witty Mr Rajoy ought to fuel dispenser be the perfect antidote to any nasty image. But he has failed to stamp his personality on the party. “He is too polite, too much of a gentleman,�complains an observer. Mr fuel dispenser Aznar s shadow lingers on as well. Polls put the Socialists ahead, though their lead varies (some say it is only 1.4 points). The head of Madrid s regional government, Esperanza Aguirre, and Madrid s mayor, Alberto Ruiz-Gallardón, may increase their majorities in regional elections next year. But they are the PP s bickerers-in-chief. As Mr Rajoy said of a new book in which Ms Aguirre lays into Mr Ruiz-Gallardón “What a troop!�Where, one might ask, is the general? © 2006 .  About sponsorship The French presidential race Candidate inflation Dec 7th 2006 | PARIS From The Economist print edition How a plethora of runners might help centrists in next spring s election ONE by one, the presidential candidates step forward—or should that be ten by ten? As many as 40 now promise to stand in France s two-round election in Apr fuel dispenser il and May. Some will struggle to secure the 500 signatures of elected officials they need. But France clearly has a bad dose of candidate inflation. The latest hopeful is François Bayrou, leader of the centrist Union for French Democracy (UDF). His declaration followed that of Nicolas Sarkozy, the interior minister and leader of the centre-right UMP party. Mr Sarkozy could face a challenge for his party s nomination from Michèle Alliot-Marie, the defence minister, when its members vote in January. But he remains the overwhelming
