Warnings, Cautions and Notices
ƽ WARNING
Hazard of Explosion and Deadly Gases!
Never solder, braze or weld on refrigerant lines or any unit components that are above
atmospheric pressure or where refrigerant may be present. Always remove refrigerant by
following the guidelines established by the EPA Federal Clean Air Act or other state or local
codes as appropriate. After refrigerant removal, use dry nitrogen to bring system back to
atmospheric pressure before opening system for repairs. Mixtures of refrigerants and air under
pressure may become combustible in the presence of an ignition source leading to an explosion.
Excessive heat from soldering, brazing or welding with refrigerant vapors present can form
highly toxic gases and extremely corrosive acids. Failure to follow all proper safe refrigerant
handling practices could result in death or serious injury.
