NOTICE: To avoid equipment damage, DO
NOT use these units as a source of heating
or cooling during the construction process.
Doing so may affect the unit's warranty. The
mechanical components and filters will
quickly become clogged with construction
dirt and debris, which may cause system
damage.
LOCATION SELECTION
To maximize system performance, efficiency and
reliability, and to minimize installation costs, it is
always best to keep the refrigerant lines as short
as possible. Every effort should be made to locate
the air handler and the condensing section as
close as possible to each other.

Air Handler Location

Locate the air handler unit in an indoor area that
10
allows easy removal of the filter and access panels,
and has enough room for service personnel to
15
perform maintenance or repair. Provide sufficient
18
room to make electrical and duct connections. If
the unit is located in a confined space such as a
closet, provisions must be made for return air to
19
freely enter that space.

Condensing Section Location

Locate the condensing section in an area that
provides sufficient room to make water and
electrical connections, and allows easy removal of
the access panels, for service personnel to
perform maintenance or repair. The condensing
section is designed for indoor use only.
