*Shipping weights include base unit plus packaging.

†If components are to be split, additional refrigerant will be needed. **Use Type L copper only.

NOTE: If components are to be split, the maximum length of refrigerant tubing to be used is 50 equivalent ft, assuming components will be installed in same horizontal plane. If components are not to be installed in same horizontal plane, contact your Bryant rep- resentative for more information.

NOTE: Fasten threaded rods through holes in end frames. Use 2 rods on each side of unit for a total of 4.

All panels must be in place when rigging.
