2.3 Ethanol and Bio-Diesel Installations
All Wayne dispensers (except DEF models) are rated and Listed for use with Ethanol blends
up to and including E10. For blends that exceed E10, the dispenser must be supplied with a
first suffix option of “9” for blends up to E25 and B20 or an “E” prefix option for blends up to
E85. “E” prefix dispensers are Listed for use up to and including E85 blends. The “9” suffix
is available for all enhanced capacity remote dispensers. The “E” prefix is only available on
remote dispenser model E3/G7107D/R. When considering an installation, all fluid handling
components must be rated for the type of fuel that will be dispensed. Piping connections for
above E10 must use UL Classified Saf-T-Lok Teflon pipe sealant.
Some alternative fuels and additives can degrade the dispenser performance and integrity if the
dispenser is not designed for that product. In addition, converting between fuel types
(especially between an alternative fuel to a standard fuel) can degrade the dispenser
performance and integrity. Before changing fuel types, always make sure that the dispenser is
designed for use with the new product. In addition, the dispenser should be closely monitored
for any sign of degradation or leaks after the conversion. This monitoring should take place in
the days, weeks and even a month after the conversion takes place. Leaks can result related to
the conversion which can create an environmental hazard.
DEF models should only dispense DEF.
2.4 DEF Installations
While DEF is not a combustible liquid, the electrical requirements as well as the proximity of
the DEF dispenser to dispensers that handle combustible liquids could dictate that various
requirements of NFPA codes be followed for a hazardous area. Wayne recommends that
DEF dispensers be installed using the same techniques and requirements that would be
applied to a dispenser dispensing flammable liquids. NPT piping connections for DEF should
use Loctite 567 sealant and Loctite accelerator 7649. Use the accelerator on both sets of
threads and allow it to dry before applying the sealant. Put the sealant on the male threads
only, being careful not to get excess inside the pipe or fittings. Do not use Teflon tape. Do
not apply sealant or Teflon tape to BSP fittings. DEF dispensers using internal DEF filter kit
require additional clearance under the base of the dispenser for the DEF filter. See the “Base
Layout” for details.
DEF models should only dispense DEF.
2.5 Existing Installations
If the dispenser is to be installed on an existing installation, it is still the responsibility of the
installer to read and follow this installation manual in its entirety and make sure the existing
installation meets the requirements and satisfies local, state, and federal codes.
