N6XX/N8XX refrigerators are designed and equipped for theuse of LP gas–propane gas–only.Incorrect installation, adjustment, alteration, ormaintenance of the refrigerator can cause personalinjury, property damage, or both.Do not smoke, light fires, or create sparks whenworking on the propane gas system.Do not use an open flame for leak testing any of thepropane gas system components. Propane gas ishighly flammable and explosive.Always use two wrenches to tighten or loosen LP gasconnections. Damaged connections, piping, andcomponents create the potential for gas leaks.All electrical connections and repairs to therefrigerator must comply with all applicable codes.Refer to the certification and code requirementssection of the N6XX/N8XX Installation Manual.Do not work on live electrical circuits. Turn off ACpower and DC power sources before attempting toremove, service, or repair any of the refrigerator'selectrical or electronic components.Do not modify, bypass, or eliminate any of therefrigerator's electrical components, electronic circuits,or propane gas system components.Do not wet or spray liquids on or near electricalconnections or electronic components. Most liquids,including leak detection solutions, are electricallyconductive and pose the potential for an electric shockhazard, short electrical components, damageelectronic circuits, and/or ignite a fire.Do not use leak test solutions that contain ammoniaor chlorine. Ammonia and chlorine degrade copper andbrass components.The cooling unit is a sealed system underpressure! Do not try to repair or recharge the coolingunit. Do not bend, drop, weld, drill, puncture, saw, orstrike the cooling unit.Handle a leaking cooling unit with extremecaution! The cooling unit contains ammonia,hydrogen, and sodium chromate. Ammonia can causesevere skin and eye burns. Hydrogen is highlyflammable, can ignite and burns with an intense flame.Certain chromium compounds, such as sodiumchromate, are carcinogenic.Do not use extension cords. Do not remove thegrounding prong from the refrigerator AC power cord.Do not use a two prong adapter to connect therefrigerator to the AC outlet.Do not over-fuse electrical circuits. Use specifiedfuses and AWG wire sizes. The specification sectionof this manual provides fuse size information. Refer tothe N6XX/8XX Installation Manual for the correct AWGwire size specifications.Prevent child entrapment! Before disposing of therefrigerator, remove all doors and fasten all shelveswith retainers.Some of the refrigerator's metal components havesharp corners and edges. Wear hand protection, suchas cut resistant gloves, and exercise extreme carewhen handling the refrigerator.Make sure all hardware such as hinges and fasteners(retaining screws, etc.), are properly fastened.SAFETY AWARENESSSafety NoticeIt is not possible to anticipate all of the conceivableways or conditions under which the refrigerator may beserviced or to provide cautions as to all of the possiblehazards that may result. Standard and accepted safetyprecautions and equipment should be used whenworking on electrical circuits and handling toxic orflammable materials. Safety goggles and otherrequired protection should be used during any processthat can cause material removal, such as whenremoving a leaking cooling unit and cleaningcomponents.Attention StatementsThe safety alert symbol followed by the wordWARNING or CAUTION identifies potential safetyhazards or conditions.The safety alert symbol with the appropriate headingappear on all safety labels posted on the refrigeratorand safety awareness notices presented throughoutthis manual.CAUTION:The above heading identifies hazards, which if ignoredcan cause injury and/or property damage.WARNING:The above heading identifies hazards or conditions,which if ignored can cause serious injury, death, and/or extensive property damage.
