General Installation Information
• The Typical Installation illustrations provided on
pages 4 - 5 are only guidelines for installing system
components. Contact your Graco distributor for
assistance in planning a system to suit your needs.
• To ensure your system is compatible with fluids
being pumped, always use genuine Graco replace-
ment parts and accessories.
• Tighten all connections firmly to avoid air and/or
fluid leaks.
• Storage tanks should be securely anchored to pre-
vent shifting or tipping when empty or full.
Identification Label for CE Mark
Locate the Diesel Exhaust Fluid (DEF) System identifi-
cation label adhered to the mounting bracket.
Use a permanent marker or ink pen to write the installa-
tion date in the space provided and circle the Part Num-
ber for the model you ordered.
FIG. 3 is provided to assist you in finding the location of
this label on the bracket and the Date Code field on the
label.
NOTICE
To maintain the integrity and purity of the AUS32
(Aqueous Urea Solution 32.5%) and ensure proper
operation of equipment:
• Once the system is assembled it must remain
sealed to insure the integrity of the fluid. Break-
ing the seal on the system can lead to fluid con-
tamination.
• After dispensing DEF, drain all the fluid from the
nozzle, making sure it is pointing downward
when stored in the nozzle holder. DEF remaining
in the nozzle tip and exposed to air will crystallize
and can plug the nozzle.
• DO NOT lay the dispensing nozzle on the ground
or on any surface that may contaminate the noz-
zle tip and compromise the purity of the DEF.
