Important!
For all roof top
installations, safety
straps must be
attached between the
hood(s) and the unit
mounting structure.
Additional Rooftop Mounting Guidelines
Ground-level installation is preferred for outdoor units that include a low
ambient kit. If ground-level installation is not possible, follow general, as
well all additional installation guidelines for rooftop mounting. If you have
any questions, please contact your distributor.
Note:
Low ambient hood(s) increase the overall height of the outdoor
units and make them more susceptible to wind stresses. Follow
all guidelines when using these for rooftop applications.
• Straps must be attached to the hood where they will not interfere with
the movement of the dampers.
Note:
For all rooftop installation, safety straps must be attached between the
hood(s) and the equipment support structure. Straps should be 3/16” (or
larger) vinyl-coated cables.
• Straps must be connected to both the hood and mounting structure
through using ¼” diameter (or larger) bolt.

attached to the structure. If the equipment support does not at-
tach to the structure, refer to the support manufacturer’s
guidelines for proper size and construction.
