How does this solvent help when servicing refrigerant systems?

The Super Flush Solvent loosens and carries away oils, varnish, and residue that accumulate inside refrigerant circuits and components. When applied correctly it reduces the risk of blockages and improves lubricant compatibility after repairs. Use it as part of a thorough flush and evacuation routine to prepare the system for new refrigerant and oil.

• Breaks down hardened oil deposits and varnish before reassembly.
• Flushes piping, evaporators, condensers, and receiver-driers.
• Prepares surfaces for new lubricant and refrigerant fills.

What’s the recommended way to use Four Seasons 69994 Super Flush Solvent?

Technicians typically circulate the solvent through the system or component to dissolve contaminants, then evacuate and properly dispose of the spent solvent. Follow manufacturer service procedures and safety guidelines: isolate the section being flushed, protect bearings and elastomers, and ensure full removal of the solvent before adding refrigerant.

• Circulate solvent using a flushing rig or by component bypass methods.
• Rinse until discharge runs clear, then fully evacuate the system.
• Replace filters/driers and lubricants as required before recharge.

Are there safety, compatibility, and disposal considerations?

Handle Super Flush Solvent with appropriate PPE—gloves and eye protection—and work in a ventilated area. Confirm compatibility with system materials; avoid prolonged contact with certain plastics or painted surfaces. Dispose of used solvent and contaminated materials according to local hazardous-waste regulations.

• Wear gloves and safety goggles; avoid inhalation and skin contact.
• Check component material compatibility before prolonged exposure.
• Collect used solvent and dispose per local environmental rules.
