DEF TANK REPLENISHMENT SYSTEM • OPERATION MANUAL — REV. #0 (09/11/20) — PAGE 9
CAN YOU MIX FRESH DEF WITH OLDER DEF?
YES.
Since adding new DEF does not change the mixture
ratio, you can mix the two together.
WHAT SHOULD YOU DO IF DEF MAKES CONTACT
WITH YOUR SKIN?
Try to avoid prolonged or repeated contact with skin. After
handling DEF, always wash your hands thoroughly with
soap and water.
If irritation occurs, flush the exposed area with plenty of
water for at least 15 minutes, then wash the area thoroughly
with soap and water. If irritation or pain persists, seek
medical assistance.
WHAT SHOULD YOU DO IF DEF MAKES CONTACT
WITH YOUR EYES?
Flush eyes with large amounts of water for at least
15 minutes. If irritation or pain persists, seek medical
assistance.
HOW DO YOU MONITOR THE DEF LEVEL?
Read the DEF gauge on the control panel of the unit. Refer
to
on page 16 section of
this manual to learn how to activate the gauge.
HOW DO I CLEAN SPILLED DEF?
If DEF is spilled while filling the tank, simply use a damp
cloth and wipe the surface clean.
CAN I USE MY UNIT TO STORE OTHER FLUIDS?
NO.
This unit is only intended for DEF and cannot be used
for storage of any other types of fluids or chemicals.
WHAT SHOULD I DO IF I SPILL DEF?
If DEF is spilled, contain the spilled liquid and absorb it with
an inert, non-combustible absorbent material, such as sand.
Shovel the material into a suitable container for disposal.
Spills into a drain should
always be avoided
. If spilled into a
drain, flush thoroughly with water. For significant quantities,
contact local authorities for proper disposal of this material
and its container in accordance with all applicable local and
national regulations.
FREQUENTLY ASKED QUESTIONS
WHAT HAPPENS IF I INGEST DEF?
DEF should
never be ingested
. If it is ingested,
DO NOT
induce vomiting. A physician should be consulted
immediately.
WHAT HAPPENS IF I INHALE DEF?
While pumping DEF will not cause significant exposure,
inhalation may occur if exposed to DEF in a closed area
or if DEF is misted into the air.
Under normal conditions of use, harmful effects are not
expected. If you inhale DEF, you should move to an area
with fresh air and obtain medical attention if symptoms,
such as irritation to the nose and throat, develop or persist.
DOES DEF HAVE AN ODOR?
DEF may have a slightly pungent odor similar to that of
ammonia, however it is completely harmless.
IS DEF CORROSIVE?
YES.
DEF is corrosive to copper and brass as well as other
materials. Only approved materials, such as high-density
polyethylene (HDPE), should be used in the DEF tank,
packaging and dispensing equipment.
CAN I ADD A FREEZE-POINT PRODUCT TO
PREVENT FREEZING OF THE DEF?
NO.
While an additive could improve the freeze point of
the mixture, the 32.5-percent solution is necessary to
provide nitrogen oxide-reducing properties. Any further
blending or adjusting of the DEF mixture will impede its
ability to perform correctly and may cause damage to the
SCR components. Additives of any kind are not approved
for use in DEF.
