NOTES
1.
Unit must be installed square and level.
2.
Curb configuration for “bottom” return and “bottom” supply.
3.
These drawings are not intended as construction documents for the field fabricated roof curbs. Johnson
Controls will not be responsible for the unit fit up, leak integrity, or sound level for installation using field
fabricated roof curbs.
4. The YPAL unit does not have a base pan under the condensing section of the unit. Field fabricated roof
curbs must have a cap on the top of the condensing section of the curb to prevent moisture from entering
the space. The cap design must be sloped away from the supply duct opening to the end of the unit for the
drainage of the moisture off of the top of the cap.
