Two Piece Cabinet Disassembly - Trane 4TEE3F48A1000A Installer's Manual

8. If the unit is installed without a return air duct, ap-
plicable local codes may limit this air handler to in-
stallation only in a single story residence & within
conditioned space.
9. If the outdoor unit is to be installed later, or by oth-
ers, then installation of the air handler must be
made to allow access for refrigerant lines, or attach
refrigerant lines to air handler when installing.
10. Make sure there are provisions for installing con-
densate drain lines.
11. If side, front or rear return is required, air handler
must be elevated
(TAYPLNM100). Connecting return duct directly to
the side, front or rear of the cabinet is not ap-
proved.
12. Route refrigerant & condensate drain lines away
from air handler so they do not interfere with ac-
cess panels and filters.
13. When external accessories are used, the additional
height and width requirements must be considered
in the overall space needed.
14. These units are not approved for outdoor installa-
tion.
15. These units are approved for draw-through application
only.
16. Flow-through Bypass Humidifiers
Excessive bypass air may cause water blow-off,
which will adversely affect system operation and air
cleaner performance. To verify bypass airflow, fol-
low the Bypass Humidifier Pre-Installation Check-
out and Set-Up Procedures available through your
local distributor. Ask for publication number 18-
CH37D1-1.
Steam and Flow-through Fan Power Duct-
mounted Humidifiers
Follow the humidifier installation instructions.
