Before Mounting the Unit on the Fuel Island
Preliminary Installation Information
Model grade mapping (inlet piping) for Encore units is different from the Advantage Series
and Multi Product Dispenser (MPD)-3 Series as well as other manufacturers’ units. Incorrect
matching of unit piping to supply lines can cause costly rework and time delays.
Encore Y and Z inlets are never used for blended products. Z is always a Straight/Unblended
Product Inlet; +Z is always a Straight/Unblended +1 Product.
Typical MPD configuration: W = Product 1, X = Product 2 and Y = Product 3. Product
number does not signify the grade on MPD units, for example; Product 1 is not always Lo
Grade, but is optionally Lo, Mid or Hi.
W = Product 1 (on Blenders only, Product 1 is always a Lo Product.)
Grade piping is always right to left when facing Side 1.
Adapting the Pit Box
For installation using an existing pit box, some modifications may be necessary. The
following list highlights the changes that may be necessary. Refer to “Installation Differences
when Replacing the Advantage Series” on page 92 for more information. These installation
considerations may also apply when you are replacing competitive units.
To adapt the plumbing/conduit to Encore stub up locations:
• Use care in sizing and routing flexible piping to avoid bends that restrict flow. This is
especially critical for pumps which may have serious issues with flow or noise if the
flexible pipe cross section becomes significantly restrictive.
• Use flexible piping in the pit box for plumbing adaptation. If piping in the previous box is
rigid, use the adaptability of the Encore hydraulic cabinet inlets and conduit entry points
instead of making modifications to rigid plumbing and conduit in the pit box.
• When adapting plumbing in the dispenser cabinet, remember that the lower piping cross
brace must be used to secure plumbing above the shear valve and that rigid piping must be
used within the dispenser.
• Modify the pit box rain lip when required (for boxes designed for the Advantage Series
wide frame units). Modifications will also typically be done to the Encore base.
• When adapting an Encore to an existing pit box or one that is not specifically designed for
the unit, the rain lip may require modification or removal. If the rain lip is removed, the
entire base of the dispenser must be sealed to the island. Study the foundation layouts and
the existing pit box to determine if modifications are required before mounting the unit on
the island. Refer to the following Warning for working in this area.
WARNING
You are working in a potentiality hazardous environment where fuels and their vapors may
be present and could be ignited with sparks from grinding and cutting tools.
Always conduct work at the required safe distance away from a hazardous area and use
the appropriate tools.
