A dispensing unit that relies on an STP in the storage tank to send fuel to the dispenser.
Grade
Indicates the fuel grade available at the nozzle. In the case of blender dispensers, a grade is
created by blending products.

Preventive Maintenance
Maintenance Procedures and Parts
Gasboy Atlas pumps and remote dispensers are designed for years of uninterrupted service.
However, certain dispenser or pump parts will experience normal wear and therefore will
require periodic inspections. For example, detecting fuel leaks that may occur, belt tension and
belt condition, lubrication and strainer cleanliness, are all important to maintain safe and
efficient unit operation. Therefore, to avoid annoying pump shut downs, a periodic preventive
maintenance inspection plan must be established and followed.
Procedures requiring leak repair, shear valve maintenance, and disassembly of portions of the
pump/remote dispenser should be performed by an ASC.
To avoid electrical shock or hazard of an explosion or fire when servicing remote dispenser/
pump:
• Shut off and lock out all power to the pump/remote dispenser (in submersible pump
applications, shut off and lock out power to the submersible pump and any other remote
dispensers that use that submersible pump. AC power can feed back into a shut-off
dispenser when remote dispensers share a common submersible pump or starter relay).
• Shut off and lock out all power to the remote dispenser and submerged pumps at the master
panel and close and test any impact valve before performing any maintenance or service to
the remote dispenser, including changing any fuel filters or strainers.
• Block the island so that no vehicles can pull up to the remote dispenser when the dispenser
is being worked on.
WARNING
Moisture from rain can damage the internal components of a pump/dispenser.
Internal components exposed to moisture may not operate correctly. Do
not
open the
electronics cabinet to perform any other tasks while it is raining.
