Mechanical Attachment Of The Dispenser - tatsuno OCEAN TOWER Series Installation And User Manual

3.4. MECHANICAL ATTACHMENT OF THE DISPENSER
Dispensers are attached to special foundation frames by using anchor bolt supplied with the dispenser.
The foundation frame of the dispenser is not a past of dispenser standard equipment but may be ordered
separately. The foundation frame is concreted into the safety island, then the front and rear covers of the
dispenser are removed, the dispenser is placed onto the foundation frame and attached by anchor bolts.
CAUTION
Where required by local regulations, for the sake of safety and environmental protection, a drip
tray is installed under the dispenser. It prevents the leakage of fuel or technical liquid into soil due to possible
leakage of the hydraulic system. The leaked liquid appears at a defined location outside the dispenser where
the operator quickly identifies it and ensures a repair of the leakage of the hydraulic system.
Then the dispenser is connected to the suction pipeline with a bellows (suction piece) that is included in
the dispenser delivery. Appendix 1 shows the foundation frames and foundation plans of all types of
dispensers with the indicated position of the suction pipeline and the pipeline for extracting gasoline
vapour from dispensers. The vapour recovery pipeline is connected to the G 1'' lid of the pipeline.
NOTE
The G 1" lid is included in the dispenser delivery. The suction line must be terminated by the G1" internal
thread.
CAUTION‐>LPG
LPG extrusion from the dispenser and pipeline, e.g., while removing the dispenser, is carried
out with nitrogen or inert gas. Extrusion by air or oxygen is prohibited!
NOTICE‐>LPG
According to EN 14678‐1: 2013, clause 4.5.1.2, the liquid phase entry into the LPG
dispenser/module and the gas phase output from the LPG dispenser/module must be protected by a device (shear
valve or break point) to ensure that the flow of liquid LPG or LPG vapour into atmosphere is prevented in case of
pipeline rupture. The shear valve or break point must be firmly attached to the frame of the dispenser and to the
ground. Shear valves are not a part of the standard delivery of the dispenser!
In the case of the CNG dispenser/module, the inlet pipeline of the outer diameter ø12 mm (standard
delivery) or ø16 mm (higher delivery /H) is inserted to the interconnecting threaded joint with a screw
ring located under the ball shut‐off valve on the dispenser and then the threaded joint is tightened. The
inlet pipeline must be fitted with shut‐off valves before its entrance to the shaft space under the
dispenser for potential disassembly of the dispenser.
CAUTION‐>CNG
Joint design must ensure perfect tightness up to the pressure of 400 bar.
CAUTION‐>CNG
The inlet pipeline of the dispenser must be secured by overpressure protection (overpressure
valve, etc.) against pressure higher than the permissible maximum operating pressure.
