DISCLAIMER: You are assuming the risk by handling materials containing refrigerants under pressure, that if not 
handled properly can cause bodily injury. If you do not feel comfortable conducting this installation process,
The symbols below are used throughout this manual to indicate instructions that should 
be followed closely or actions that should be avoided to prevent death, injury, and/or property damage.
This symbol indicates ignoring instructions may cause bodily injury, damage 
to the unit, or other surrounding property.
