1.1 Features
Some of the features of Helix dispensers are listed below:
•
Most current circuit design and functionality, with expansion capabilities for various types of
displays and future options
•
New two-piece bezel
•
Many of the outside components and bezel parts snap in place and do not require hardware
•
Improved serviceability of hydraulic components — valves, meters, and outlet castings. Using
the new tube removal tool, there is no longer a need to use ladders when replacing product
tubes
•
New filter/strainer casting and attached funnel to reduce fuel spills when changing filters
•
Newly designed dual vapor barrier with a 1-1/2 inch space between the two barriers eliminates
need for lock nuts above and below the barrier. This makes changing valve coil/conduits
much easier. WIP cables and nozzle switch wires are no longer in a potted fitting and can be
replaced individually
•
New power on/off switch located by the iGEM board shuts down power in the dispenser
•
Easily replaceable nozzle boots
•
Incorporates use of USB printer
The following sections in this manual give details on the new hydraulic and electronic components
