Installation Considerations

• Isolation rails should not be installed on top of Trane roof curbs. If isolation rails or isolation

curbs are required, the entire curb system should be supplied by a specialty curb company.

Note: For proper operation, the unit must be supported around the entire unit base perimeter.

The roof curb must be supported along its entire perimeter. The curb may be set parallel or at right

angles to roof support members. If at right angles to the support members, there must be adequate

supporting roof cross members between the ends (in the direction of airflow). Be sure the cross

members do not interfere with the connection of supply and return ducts to the unit. See Figure 2

for details.

• When mounting the unit on its roof curb, make sure that the gasketing between the roof curb

and unit base provides an airtight seal.

Note: When pulling shipping split sections together, the field-supplied gasket material may bunch

up between bases. Make certain this does not prevent tight contact between shipping

sections.
