NOTE ABOUT WALL HOLE:

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.
If you are planning on mounting air handlers to interior walls, there are some aspects that need to
be considered when it comes to drilling a wall hole and routing line sets to the outdoor condenser. If
you are not able to mount air handlers to exterior walls, you will need to run the line sets to a central
location within the house, such as an attic, basement, or crawlspace, and have them exit the house
(to the outdoor unit) from that location. Another aspect to consider is the condensate drain pipe. A
drain pipe is necessary to allow water (condensate) to exit the air handler. If you mount an air
handler in a location that is difficult to run a drain hose down and outside, it may be necessary to
use a condensate pump (not included, but available from online retailers). These are used to pump
the water from the air handler and prevent it from ruining the interior of your home.
