1.   Safety Considerations
Improper installation, adjustment, alteration, service, maintenance, or use
can cause explosion, fire, electrical shock, or other conditions which may
cause  death,  personal  injury  or  property  damage.  Consult  a  qualified
installer, service agency or your distributor or branch for information or
assistance. The qualified installer or agency must use factory-authorized
kits  or  accessories  when  modifying  this  HVAC  system.  Refer  to  the
individual  instructions  packaged  with  the  kits  or  accessories  when
installing.
Follow  all  safety  codes.  Wear  safety  glasses,  protective  clothing,  and
work gloves. Have a fire extinguisher available. Read these instructions
thoroughly  and  follow  all  warnings  and  cautions  included  in  literature
and  attached  to  the  unit.  Consult  local  building  codes  and  the  current
edition of the National Electrical Code (NEC) NFPA 70. In Canada, refer
to the current editions of the Canadian Electrical Code CSA C22.1.
Recognize safety information. When you see this symbol   on the unit
and  in  instructions  or  manuals,  be  alert  to  the  potential  for  personal
injury.  Understand  the  signal  words  DANGER,  WARNING,  and
CAUTION.  These  words  are  used  with  the  safety-alert  symbol.
DANGER identifies the most serious hazards, which will result in severe
personal  injury  or  death.  WARNING  signifies  hazards,  which  could
result in personal injury or death. CAUTION is used to identify unsafe
practices,  which  may  result  in  minor  personal  injury  or  product  and
property  damage.  NOTE  is  used  to  highlight  suggestions  which  will
result in enhanced installation, reliability, or operation.
