Important Considerations for DEF Dispensers
Preparing to Service Units
4 – Preparing to Service Units
This chapter provides instructions for collecting information on any unit-related problems that
a Gilbarco-trained Authorized Service Contractor (ASC) or Customer Specified Contractor
(CSC) will require for servicing. Providing complete information can shorten the time
ASCs/CSCs spend troubleshooting the problem and enable them to have the correct parts
required for service.
Do not attempt to service an Encore or Eclipse pump/dispenser yourself without special,
qualified training. Servicing an Encore or Eclipse pump/dispenser incorrectly could result in
severe injury or death. Only Gilbarco-trained ASCs/CSCs must service an Encore or
Eclipse pump/dispenser.
WARNING
Do not make unapproved modifications to Gilbarco equipment. Doing so could result in
improper equipment operation and violation of state and local codes, and could also create
a safety hazard. Consult your ASC/CSC, distributor, or Gilbarco for approved modifications
and kits.
WARNING
Important Considerations for DEF Dispensers
Applicable during Installation and Operation of the Dispenser: DEF freezes at approximately
-11.5 °C (11 °F). Power to the dispenser and heater must always remain ON in cold weather. If
power is lost and the temperature drops below this point, the system must be inspected for freeze
damage before restart. For sites that experience occasional power losses or for sites that are
located in very cold climates, it is recommended that a backup power generator be used to
maintain constant power to the dispenser. Do not use any additives to lower the freezing point of
DEF. Additives of any type must not be used in DEF. Freezing can cause damaged or inoperative
hose breakaways, fluid lines or components, valves, nozzles and meters.
Prolonged storage at temperatures above 25 °C (77 °F) can impair the quality of DEF and reduce
its shelf life.
CAUTION
DEF is mildly corrosive. It can corrode components that are made from incompatible materials and
reduce their integrity. The use of incompatible materials may lead to leaks and spills, and can
contaminate and degrade the DEF. When dispensing DEF, verify with the manufacturer if the
material of all plumbing components are compatible with the DEF being dispensed.
CAUTION
