Product Information
Product Quality
Using best practices leads to the best quality product. Why
do anything less than your best when packaging a premium
product? This bulletin is a short summary of the informationthat can be found in more detail in the Opteon™ YF Properties,
Uses, Storage, and Handling (PUSH) Bulletin and the Safety
Data Sheet (SDS).

Best Practices—Handling• Ensure that the storage tank and transfer lines are clean
before working with Opteon™ YF refrigerant. If thecylinders are not clean or suspected of being
contaminated, clean the suspected contaminated tankand lines with mild detergent or warm water.
• Ensure that the storage tank and lines are dry before
transferring refrigerant into them. Purge the tank andlines with dry nitrogen (99.99% purity), which has amaximum moisture specification of 10 ppm.
• Ensure that the storage tank and lines are evacuated toa minimum of 5,000 microns (0.01 barA) or less prior tofilling with refrigerant.

Best Practices—Packaging• Do not repackage Opteon™ YF into cylinders that have aleaking valve or where the valve has been left open.
• Do not fill refrigerant into Opteon™ YF cylinders withexcessive amounts of air or moisture. This can lead topoor product quality and impact release specifications.

• Ensure that the cylinders used for packaging Opteon™
YF are clean and properly prepared for packaging
refrigerant.
• Ensure that the refrigerant charging line has beenthoroughly prepared and does not introduce
contaminants into cylinders.
• Once cylinders are properly filled, ensure that valves aretightly closed and quality or shrink seals have been applied.

Best Practices—Storage• Always follow the SDS that can be found at
www.Opteon.com.
• Cylinders should be stored upright and firmly secured toprevent falling or being knocked over.
• Separate full containers from empty containers.
• Do not store near combustible materials.
• Avoid areas where salt or other corrosive materials arepresent.
• Keep in properly labeled containers.
• Keep in cool, well-ventilated place away from direct
sunlight.
• Small cylinders should be stored at temperatures nogreater than 52 °C (125 °F).

RefrigerantQuality Best Practices
There have been some instances where system
contamination has led to the appearance of a whitematerial that can appear as a whitish residue or string. Toavoid, do not overlook the small points in refrigerant transfer,storage, and handling installations. Common points that canhave a major impact on refrigerant quality are storage tanks,transfer lines, and package cleanliness.
Do not let chemicals, such as thread locking agents orsealants, get into the system and possibly lead tocontamination and incompatibility. There are at least several
hundred different thread locking agents; and, while one
from a particular family may be compatible with Opteon™
YF, this does not ensure that all products are compatible.
These may have a negative interaction with Opteon™ YF,generating a white material.
Do not use strong cleaning agents to clean storage tanks,transfer lines, filling equipment, and/or cylinders. WhileOpteon™ YF has good material compatibility and stability,
it is not compatible with strong oxidizers—such as thosefound in peroxide-type cleaning agents. Cleaning agentsthat bill themselves as natural or friendly may also containstrong oxidizing agents and must be avoided.
