keep good earthing and sealability and conduct pressure –resistance test as regulation in national standard GB50156-2002. Don’t input oil or burry tank before pressure testing. Diagram 5-4: Correct installation of fuel dispenser and tank The inlet pipe of tank should be mounted bottom valve, which is vertical and 100mm higher than tank bottom. As crucial to fuel dispenser’s normal operation, bottom valve should have good sealability and performance. It is prohibited to connect fuel dispenser with semi-underground tank, above ground tank and high position tank. If oil level is higher than vapor separator exhaust pipe would overflow leading to insecurity working circumstance. Given have to adapt one of above tank, the ex fuel dispenser haust pipe of vapor separator should be sealed in case oil overflow out. Match of fuel dispensers and tank: if adopt one tank delivering oil to two or more fuel dispensers each fuel dispenser should have single pipe without interconnection. Diag fuel dispenser ram 7-4 shows the right connection. Diagram 5-5 is wrong one. Diagram 5-5: Inappropriate installation of fuel dispenser and tank If one fuel dispenser is connected to two or more tanks valve is necessary to be installed in pipeline. fuel dispenser Diagram 5-6 illustrates this kind of connection. In short, the connection of fuel dispensers and tanks, whatever working circumstance, should comply with the basic principle that one tank, one valve and one pipe are connected with one fuel dispenser. Otherwise, the normal measuring function of fuel dispenser would be affected. Diagram 5-6: Combination of two or more tanks Electric Installation The general power switch is installed indoors, switch fuse is defined as the current of motor when starting. The earthing line of fuel dispenser should firstly connect with ground device of filling station before electric installation. Power wire of fuel dispenser should connect into TN-S power supply system, compatible to TN-C-S and TN-C systems. Lead and wire should be five-bind copper thread with two protective

The European Commission this week reported on two official candidates, Croatia and Macedonia, and assessed progress in Albania, Bosnia, Montenegro and Serbia. Olli Rehn, the enlargement commissioner, said all were on track, but added that it is “no bullet train, no Eurostar, no TGV...it is a slow, slow train� fuel dispenser Yet these smaller fry have been getting more positive signals than has Turkey. Earlier this year, European foreign ministers repeated a pledge that all Balkan countries had a future in the European Union. Even so, the promise came with a cav fuel dispenser eat that the speed of enlargement must take account of the EU s “absorption capacity� The commission report tries to allay fears on both sides. It says firmly that the EU must not renege on its promise. Countries will also be given fuel dispenser more money to help them on their way over the next three years, Croatia will get around �36m ($560m) and Macedonia �10m. But the commission also wants to show that its support is not unconditional. It says both Croatia and Macedonia must do more to tackle corruption. Many in Brussels think the EU let in Bulgaria and Romania, which will join in January, prematurely. The commission report reflects on “lessons learnt�from Bulgaria and Romania about the importance of tackling corruption and judicial reform at an early stage. The commission also discusses the preparedness of the EU for further expansion. Mr Rehn admits that the EU s “integration capacity�(the newly approved jargon to replace “absorption capacity� must be considered. He also repeats that there should be no more ex
