System should consist of only metallic sprinkler piping. No plastic piping (CPVC, PEX etc.) shall be installed on the system. Potter Pipe-Shield shall be used at 0.5% concentration by fire sprinkler system volume on all wet systems. The inhibitor shall be pumped in using either the Potter Portable Chemical Injection System (Model PCIS-B) or Potter Chemical Delivery System (Model PCDS-B). All systems must be vented of air during treatment using the Potter Air Vent (Model PAV) or Potter Automatic Air Release Vent (Model PAAR-B) located at the high point(s) in the system. Furnish and install a valve in the fire sprinkler riser above the inspectors test valve. The check valve assembly shall include a 2” drain valve and a ½” tap (pump connection) with ball valve located above the check valve. Treated water discharged from the fire sprinkler system(s) shall be approved by the AHJ for storm drain and or sanitary sewer water prior to discharge. Potter Pipe-Shield concentration be confirmed using the Potter Test kit prior to putting system in service. Photos of the concentration shall be provided to the owner after treatment to confirm treatment. B. Potter Corrosion Delivery System (Model PCDS-B) Furnish and install a Potter Corrosion Chemical Delivery System, PCDS-B, that is a self contained system manufactured specifically for automatic fire sprinkler systems. The unit shall be designed to pump non-hazardous, bio-static corrosion inhibitors into the sprinkler system upon the operation of a dedicated manual ON/OFF switch. The pump shall deliver the corrosion inhibitor at a flow rate of 0.4 GPM (±0.15 depending on system pressure) into the system. The pump shall be stainless steel. The pump shall only be turned on when new water is flowing into the system. The cabinet should hold one 15 gallon, or two 5 gallon corrosion inhibitor factory delivered containers with a 24 gallon polyethylene secondary containment tank. Only corrosion inhibitors compatible for use with the components of the chemical delivery system, such as Potter Pipe-Shield shall be used. C. Portable Corrosion Injection System (Model PCIS-B)
