10 All external piping must be protected against freezing of the DEF fluid that can cause severe
damage to piping components or the dispenser with accompanying leaks. It is recommended to
use reflective or light color insulation for insulation exposed to direct sunlight.
Start-up
After successfully verifying the installation against the completion checklist, the unit is ready
for start-up.
To perform an orderly start-up of the Atlas electronic series unit, proceed as follows:
1 Ensure that all switches and jump jacks on the CPU PCB are set properly to various operating
conditions.
2 Turn on circuit breakers for the microprocessor and fluorescent lights. Ensure that both lights
are lit.
3 Authorize the hose for side 1 through the FMS, if available.
4 Remove the nozzle for side 1 from its holder and turn on the pump handle. Ensure that the
display goes through a proper reset sequence.
5 Dispense the fuel. Ensure that the high flow valve opens, if equipped. Check all plumbing for
leaks at this time.
6 Turn the pump handle off. Open the nozzle. No fuel must be dispensed at this time.
7 Ensure that the correct quantity is recorded by the FMS, if available.
8 If applicable, repeat steps 3 through 7 for side 2.
9 Run the unit through all standard calibration procedures.
10 Reset the electronic totalizers.
CAUTION
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.
