Operation
CAUTION
Always have appropriate fire fighting equipment on hand while undertaking servicing and filling
operations.
6.1
Fuel Filling
Fuel filling operations must be undertaken in accordance with site procedures. Incorrect fuel filling operations can
cause early shut off and possible diesel showers. In no circumstances shall the operator manually override the
automatic fuel filling gun closing mechanism. This may occur when the operator secures or tampers with the filling gun
to force it to stay on.
CAUTION
The automatic fuel filling system must not be manually overridden.
6.2
Flow Specification
Each of the Hydrau-Flo
®
Valve components has a rated flow specification that they are rated for. If these ratings are
exceeded the integrity of the system is not guaranteed and the owner will be liable for any damage caused to the
system due to incorrect operation. Before any filling operations the operator must ensure that the pump stations rated
flow specifications comply with the rated flow capacities of the installed Hydrau-Flo
®
Valve components.
CAUTION
Pump station flow specifications must be synced with the rated flow capacity of the installed
Hydrau-Flo® Valve components.
6.3
Fuel Filling of Dual Tanks
When undertaking fuel filling operations with dual tanks, due to manometer effects between the tanks the filling for the
second tank is slower and actual level results in over filling which can be further increased by fuel reticulation.
CAUTION
Make sure correct installation of the dual tanks and make sure the valve is in the right location
of the tanks.
6.4
Multiple Filling Valves Flow Rating
If multiple filling valves are installed and a single Float Control valve is used, the combined flow rate of the filling valves
must not exceed the rated flow capacity of the float control valve. If the flow capacity exceeds the float control valve, a
secondary float or breather is required.
CAUTION
Ensure combined flow rate of multiple Fuel Filling Valves match the rated flow capacity of the
installed Hydrau-Flo® Valve components.
