INDICATORS AND NOTATIONS
Danger indicates a hazard or unsafe practice which, if not avoided, will result in severe injury or
possibly death.
Warning indicates a hazard or unsafe practice which, if not avoided, may result in severe injury
or possibly death.
Caution indicates a hazard or unsafe practice which, if not avoided, may result in minor injury.
Important information to consider, otherwise, improper installation and/or damage to
components may occur.
DEF DISPENSER CONSIDERATIONS
Human Exposure: Avoid contact with eyes, skin, and clothing. Refer to Material Safety Data Sheet
(MSDS) for detailed safety information. In case of contact with eyes, immediately flush with water for
at least 15 minutes, occasionally lifting the upper and lower eyelids. In case of skin contact,
immediately flush skin with plenty of water for at least 15 minutes while removing any contaminated
clothing and shoes. Wash clothing and clean shoes before reuse. In both cases, get medical
attention if symptoms occur.
Temperature: DEF freezes at approximately 12
º
F. This dispenser provides no heating for
protecting the DEF on against cold temperatures. While allowing DEF to freeze does not damage
the DEF, it can damage the fluid containing components of the dispenser. This dispenser should not
be used in areas where the ambient temperature will go below 12
º
F to prevent the DEF from freezing.
If the DEF in the dispenser is allowed to freeze, components in the dispenser must be inspected for
damage before the dispenser is placed back into service. Additives may not be used in DEF to lower
the DEF freezing point. Prolonged storage above 77
º
F can impair the quality of DEF and reduce its
shelf life.
Compatibility: DEF can cause corrosion of components that are made from incompatible materials.
Using incompatible materials can also contaminate the DEF which can potentially damage the
vehicle’s Selective Catalytic Reduction (SCR) system. Use only materials in the installation that are
known to be compatible with DEF.
Prover Cans: Prover cans designed and/or used for motor fuels must not be used for measuring
DEF nor should DEF Provers be used for measuring motor fuels. Contaminating the DEF with motor
fuel can potentially damage the vehicle’s SCR system.
Disposal: During testing and calibration, DEF is dispensed into containers or the prover can. This
DEF must be properly handled to prevent contamination of the DEF (if it is to be reused) and any
potential ground water contamination (if it is to be disposed of). See PEI Recommended Practices for
the Storage and Dispensing of DEF (RP100-10).
Sealant: When making connections on NPT pipes, it is important to use the correct sealant to reduce
the possibility for leaks. Loctite 567 is recommended to be used as a sealant along with Loctite
activator 7649. Apply the activator onto both surfaces and allow it to dry before applying the sealing
compound. Follow the manufacturer’s instructions for use of these materials. Do not use Teflon
tape. Do not use any sealing compound on BSPP fittings. These fittings are provided with an o-ring
which forms the proper seal.
Recommended Practices: Refer to PEI publications RP1100 Recommended Practices for Storage
and Dispensing of Diesel Exhaust Fluid (DEF) for additional information and guidelines for working
with a DEF installation.
