loCaTIoN
Locate the unit in an indoor area that allows easy
removal of the fi lter and access panels, and has
enough room for service personnel to perform
maintenance or repair. Provide suffi cient room to
make fl uid, electrical, and duct connection(s). If the
unit is located in a confi ned space such as a closet,
provisions must be made for return air to freely enter
the space. On horizontal units, allow adequate room
below the unit for a condensate drain trap and do
not locate the unit above supply piping. These units
are not approved for outdoor installation; therefore,
they must be installed inside the structure being
conditioned. Do not locate in areas that are subject
to freezing.
