Install Manual

NOTE ON INSTALLATION OF A DIY MULTI-ZONE SYSTEM
Please read this instruction manual fully before you attempt to
install this system. Because there are multiple units, pipes, and lines
to be installed in different locations, and heating/cooling zones to
consider, planning your installation is necessary in order to help
prevent any potential problems. Taking proper measurements is
also vital to determine the line set lengths needed to connect the
indoor units to the outdoor unit. If you find the standard line set
length is not sufficient for your application, you may need to
purchase additional line sets and coupler kits. It should be noted
that it is easier to install the air handlers to the outer walls. If they
are to be mounted to interior walls, line sets will need to be run to a
central location, such as an attic, basement, or crawlspace, and have
them exit the house (to the outdoor unit) from that location.
