Indoor Unit Installation
If there is no fixed refrigerant piping: 
While choosing a location, be sure that 
you leave ample room for a wall hole 
(see the Drill Wall Hole for Connective 
Piping step on the following pages) for 
the signal cable and refrigerant piping, 
which connect the indoor and outdoor 
units. The default position for all piping 
is the right-hand side of the indoor unit 
(while facing the front of the unit). After 
the piping and signal wire are installed, 
use the provided neoprene (spray foam 
can be used instead, if you prefer) to 
pack the space left in hole, in order to 
seal it and make it airtight.
