ANSUL FLUSHING CONCENTRATE 32OZ FOR FLUSHING R-102, 079656

The ANSUL Flushing Concentrate (P/N 079656) is a 32-oz. specially formulated cleaning agent used for flushing ANSUL R-102 restaurant fire suppression systems after a system discharge or during scheduled maintenance. Following a system discharge, wet chemical agent residue remains throughout the piping network, nozzles, and actuation tubing. This residue — if not properly removed — can crystallize inside the fire suppression system piping, block nozzles, and cause corrosion of stainless steel and copper components over time. The ANSUL flushing concentrate ensures complete removal of spent wet chemical agent, preparing the system for recharging with fresh agent.

Proper flushing is a mandatory step in the ANSUL R-102 system post-discharge service procedure and is required before any ansul fire suppression system is recharged. Skipping the flushing step or using an incorrect cleaning agent violates the ANSUL R-102 service manual requirements and can result in residue blockage that causes a discharge failure during the next real fire event. The 079656 is the OEM-specified flushing concentrate formulated to be compatible with all ANSUL R-102 ansul system piping materials and ansul nozzles without causing damage to the stainless steel, copper, or brass components of the system.

For fire protection contractors servicing ansul kitchen systems, the 079656 belongs in every ANSUL R-102 post-discharge service kit alongside fresh agent, new nozzle caps, and replacement cartridges. It is an essential item in any fire suppression supply inventory serving the restaurant fire suppression market, including ANSUL ansul fire suppression systems, ansul kitchen systems, and compatible systems that share the R-102 piping architecture. Keeping a supply of the 079656 on the service vehicle ensures technicians can complete the full post-discharge service procedure in a single visit without waiting for parts.

When to Flush

The ANSUL R-102 system must be flushed immediately after every discharge — accidental or actual fire response. Do not allow wet chemical agent residue to dry and crystallize in the piping. The longer residue remains in the system before flushing, the more difficult it becomes to remove and the greater the risk of permanent blockage at ansul nozzles and piping elbows. Flushing is also required during any scheduled internal examination of the system piping per the ANSUL R-102 service manual.

Dilution and Application

Dilute the 079656 concentrate per the ANSUL R-102 service manual instructions before introducing it to the system piping. Never use undiluted concentrate directly in the piping — the correct dilution ratio is specified in the ANSUL service documentation. Flush the complete system from the agent cylinders through all distribution piping and nozzle orifices, verifying clear flow at every ansul nozzle outlet before completing the procedure.

Disposal

Dispose of flushing effluent per local environmental regulations. Wet chemical agent residue and the flushing concentrate mixture may require special disposal as a chemical waste stream depending on your jurisdiction. Consult your local environmental compliance authority before discharging flushing effluent to the municipal sewer system.

Can I use a generic cleaning agent instead of the 079656?

No. The ANSUL 079656 is the OEM-specified flushing concentrate formulated to be chemically compatible with ansul fire suppression systems piping materials and agent chemistry. Using a non-approved cleaning agent risks damaging the stainless steel, copper, or brass components of the ANSUL R-102 system and voids the system's compliance with ANSUL service requirements. Always use the ANSUL-specified concentrate for R-102 flushing.

How much flushing concentrate do I need for a full R-102 system flush?

The quantity required depends on the size of the ansul system and the length of distribution piping. Consult the ANSUL R-102 system manual and the ANSUL parts list for your specific system configuration to determine the correct flushing solution volume. For larger ansul hood system installations, multiple 32-oz. bottles may be required to achieve a complete and thorough flush of the entire piping network.

Is this product compatible with Pyro-Chem and Range Guard systems?

The 079656 is specifically formulated for ANSUL R-102 wet chemical systems. Pyro-Chem and Range Guard restaurant fire suppression systems have their own manufacturer-specified flushing and cleaning protocols. Always use the flushing agent specified by the system manufacturer — consult the pyro chem fire suppression system manual or Range Guard service documentation for their respective post-discharge procedures.
