3. Position the Unit
When mounting the unit on a roof, be sure the roof will support
the unit’s weight obtained from nameplate. Properly selected
isolation is recommended to prevent sound or vibration
transmission to the building structure.
When installing the unit on a support pad, such as a concrete
slab, consider the following:
•
The pad must be 1~2” larger than the unit on all sides.
•
The pad must be separated from any structure.
•
The pad must be level.
•
The pad must be high enough above grade to allow for
drainage.
•
The pad location must comply with National, State and Local
codes.
IMPORTANT NOTE:
These instructions are intended to provide a method to tie-down unit to cement slab as a securing procedure
for high wind areas. Check local codes for tie-down methods and protocols.
