Pit Box Mounting
• Use strongly designed pit boxes that will not twist, bend, or dislocate the shear valve
during a collision.
• Use a pit box which will allow proper access to components during service, does not
expose the pit after unit mounting and properly fastens and supports the unit.
• Anchor pit boxes per pit box manufacturer’s recommendations. Use recommended
fasteners and tighten to manufacturer’s instructions.
• Pit boxes with rain lips are recommended. Otherwise, sealing at the base of the unit may
be required.
• The 9862 DEF unit requires four mounting points, one in each corner.
Safety Signs
• Safety signs warning of potential hazards may be required depending on state and local
codes, and NFPA regulations.
• Gasboy requires installing applicable signs in locations likely to be noticed and read by
users of the equipment.
• Signs must be easily read, bilingual, durable, and fade resistant. Unless local regulations
dictate otherwise, nationally recognized safety symbols with brief text are recommended.
• Signs must include, but are not limited to the following:
— Use approved containers
— Turn vehicles off during fueling
— Static electricity hazards during fueling
— Health-related warnings (involving fuels), advisement of fuel
flammability/explosiveness, and others, as required or desirable
— No smoking/match warnings
— Emergency procedures
