Use and Care Manual
NOTE ON INSTALLATION OF A DIY SINGLE-ZONE OR MULTI-ZONE SYSTEM
Please read this instruction manual fully before you attempt to install the cassette as part of a
single-zone or multi-zone system. There are many considerations to make installing either system.
However, because there are multiple units, pipes, and lines to be installed in different locations, and
heating/cooling zones to consider in a multi-zone system, planning your installation is extremely
important 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 in a multi-zone system, with multiple line sets, the
line sets may 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.
