Installing the unit
Discharge Conversion
If a unit is to be converted to
Vertical discharge, a panel must be
acquired from Trane.
If a unit is to be converted to
Horizontal discharge, the following
conversion must be performed:
1. Remove the return and supply
duct covers.
2. Apply gasket to the return duct
cover.
3. Position duct covers as shown in
Figure 4. The supply duct cover is
installed (insulation side down)
over the downflow return
opening by engaging one side of
the panel under a retaining angle
and securing the other side with
3 screws.
4. Slide return duct cover
(insulation side up) into supply
openings until outer edge of the
duct cover engages with the two
retaining clips on the duct
flanges. Secure the outer edge of
the each duct cover with two
screws.

Unit mounting on roof
Fix the rooftop curb on the joint
beam of the building's structure.
Make the rooftop curb's sealing
surface level using angle brackets
adjusted by screw bolts, located
around its perimeter. Place the
adhesive seals on the curb's sealing
surface (perimeter and cross
pieces). Make the rooftop leak-tight
around the curbs before installing
the unit, in compliance with current
construction standards.
Note:The unit must be installed
perfectly level to ensure
condensates flow from the
condensate tray.
The rooftop unit nests into the curb
and is supported by it. Position the
unit, taking care to comply with the
indicated directions: the unit's
discharge and intake openings must
match those of the curb.
