NOTE:  
− If the outdoor unit is higher than the indoor unit, prevent rain from flowing into the indoor unit along the connection pipe by making
a downward arc in the connection pipe before it enters the wall to the indoor unit. This ensures that rain drips from the connection
pipe before it enters the wall.
− Piping and the interconnecting wiring are field supplied.
− The illustration above is only a sketch. Different models may be slightly different.
The following units are covered in these installation instructions.
