Carrier 39T User Manual

Field Assembled Blow-Thru Units — Both single-
and multi-zone units are built for horizontal intake and dis-
charge. Because the different discharge arrangements are con-
structed from non-interchangeable parts, they cannot be
converted in the field. Single- and multi-zone installation is
described in the following sections; see Fig. 19 and the zone
damper instructions to field-install devices in the blow-thru
discharge.
COOLING ONLY, SIZES 07-92AND HEATING/COOLING,
SIZES 07-49 — All components are completely factory as-
sembled and shipped in one piece.
HEATING/COOLING, SIZES 61-92 — Heating coils and
zone damper sections are shipped out of their normal posi-
tions on separate skids.

3. Rig the zone damper section and lift it into position on
(vertical discharge) or next to (horizontal discharge) the
gasketed cooling and heating coil sections.
