for specific dimensions before attempting to install.
Horizontal recessed/concealed units must meet the
requirements of the National Fire Protection
Association (NFPA) Standard 90A or 90B concerning
the use of concealed ceiling spaces as return air
plenums. Refer to the submittal for specific
dimensions of ceiling openings.
6. Exterior: Touch up painted panels if necessary. If
pa
nels need paint, sanding is not necessary. However,
clean the surface of any oil, grease, or dirt residue so
the paint will adhere. Purchase factory approved touch
up epoxy paint from your local Trane Service Parts
Center and apply.
Service Access
Service access is available from the front on vertical units
and from the bottom on horizontal units. Cabinet and
recessed units have removable front or bottom panels to
allow access into the unit. See Figure 2, p. 11 for
recommended service and operating clearances.
Units have either right or left hand piping. Reference
piping locations by facing the front of the unit (airflow
discharges from the front). The control panel is always on
the end opposite the piping.
The fan board assembly and main drain pan are easily
removable for cleaning. See “Maintenance,” p. 106 for
more details on servicing.
