1) The machine should be installed under the awning ,the covering performance of which should apply at any season ,the location and operation area of the machine must be prevented from drenching and directly insolating .The height of the awning should insure big vehicles can pass in and out freely .

2) The machine should be fixed on the fueling island ,which bears two purposes :First, prevent the machine to be collided by the user's vehicles. Second, enhance the circumstance safety, because the bottom of the machine is higher than the ground, the oil-air density under which is lower than the ground, enhancing the anti-proof performance.

3) The bottom of the machine should be installed on the special cement base, fixed by ground bolts or expanding bolts , the corresponding location of every type machine please reference the installation dimension diagram. Oil-transporting pipe, wire pipe, signal wire pipe, down-lead of grounding equipments should be pulled out and buried in advance from the pipe pit, which should be filled with sand after completing installing the machine to avoid oil-gas amassing and diffusing .

4) The oil-transporting pipe outlet buried in advance should be higher than cement base, after the oil-tran sporting pipe is equipped with low flange and the ripple pipe is equipped with airproof mat, connect them tightly with screw .
