WARNING
Risk of Unit Dropping!
Improper use of the tie down brackets could result in
unit dropping and crushing technicians which could
result in death or serious injury, and equipment
damage. Do not use skid tie down brackets to lift the
unit. Tie down brackets are designed only to secure the
unit to the floor, housekeeping pad, or platform.
Using a Field-Provided Mounting Frame
If a field-provided mounting frame is used for ceiling
suspension, the installer/contractor must provide a ceiling-
suspended mounting frame designed to support the length,
width, and weight of the entire air-handling unit. See the
Dimensions and Weights chapter for approximate weights.
Note: It is the building engineer's responsibility to size the
structural channels and to provide the appropriate
hangers.
Structural channels in a field-provided frame can be mounted
parallel to airflow or perpendicular to airflow:
26
•
For parallel-to-airflow channels, size channels based on a
four-point load distribution.
•
For perpendicular-to-airflow channels, size channels
based on the load distribution of the individual sections and
install the channels so that both ends of every section are
supported.
