Note: 1. The weights shown in this table represents the typical unit operating weights for the
 
   heating/cooling function indicated with an economizer and exhaust fan installed.
          2. The weights shown represents the typical unit operating weights for the
              heating/cooling function indicated with an economizer, exhaust fan with supply &
              exhaust VFD installed.
          3. Roof curb weights include the curb and pedestal.
Roof Curb and Ductwork
The roof curbs for 20 through 130 Ton units consists of two
main components; a pedestal to support the unit’s con-
denser section and a "full perimeter" enclosure to support
the unit’s air handler section.
Before installing any roof curb, verify;
1. That it is the correct curb for the unit,
2.  That it includes the necessary gaskets and
hardware,
3. That the purposed installation location provides
the required clearance for proper operation.
4. Insure that the curb is level and square. The top
surface of the curb must be true to assure an
adequate curb-to-unit seal.
Step-by-step curb assembly and installation instructions
ship with each Trane accessory roof curb kit. Follow the in-
structions carefully to assure proper fit-up when the unit is
set into place.
Note: To assure proper condensate flow during
operation, the unit (and curb) must be as level as
possible. The maximum slope allowable for rooftop
unit applications, excluding SSH_'s, is 4" end-to-
end and 2" side-to-side. Units with steam coils
(SSH_'s) must be set level!
If the unit is elevated, a field constructed catwalk around the
unit is strongly recommended to provide easy access for
unit maintenance and service.
Recommendations for installing the Supply Air and Return
Air ductwork joining the roof curb are included in the curb
instruction booklet. Curb ductwork must be fabricated and
installed by the installing contractor before the unit is set
into place.
Note: For sound consideration, cut only the holes
in the roof deck for the ductwork penetrations. Do
not cut out the entire roof deck within the curb
perimeter.
