Attmt 3 - AMEREX Manual NOVEC-Wheeled Units MOD 775 776R.pdf

This is an Owner's Service Manual for Amerex NOVEC wheeled fire extinguishers (Models 775 and 776), providing installation, operating, servicing, and maintenance instructions for qualified service personnel.

The manual specifies that all fire extinguishers must be installed, inspected, and maintained per NFPA 10 standards and applicable national fire codes. Installation requires positioning the extinguisher at least 50 feet from potential fire hazards in locations with unobstructed access, maintaining operational temperatures between -40°F and +120°F. Operation involves moving the extinguisher within 30 feet of the fire, twisting and pulling the pin to open the discharge valve, extending the 40-foot hose, aiming at the base of flames, and sweeping side to side for approximately 23 seconds of discharge. The extinguisher requires immediate recharge after any use. Periodic inspections must occur monthly or more frequently, verifying proper location, pressure gauge readings, safety seals, physical condition, and wheel functionality. Complete maintenance procedures include cleaning, checking weight tolerances, inspecting cylinders for damage, testing pressure gauges, checking valves and hoses, lubricating wheels, and verifying carriage assembly integrity. Every six years, the extinguisher must be completely emptied and subjected to full maintenance procedures, including disassembly and replacement of valve stem assemblies with new Amerex parts lubricated with V-711. Recharging requires using only dry nitrogen at a minimum dew point of minus 70°F, with regulator pressure set no more than 25 psi above operating pressure. The manual emphasizes using only factory replacement parts and warns against substitute parts that void the warranty and UL listing.
