Detail A
Post and Rail Mounting
The unit must be level side to side and over the entire length.
Equipment damage can result if the unit is not level.
When mounting by post and rail, run the structural support the
full length of the unit. Locate the structural member at the base
of the unit as shown in
Figure
supported by the structural member.
If resilient material is placed between the unit and the rail, insert
a heavy steel plate between the unit and the resilient material to
distribute the load. Seal cabinet penetrations (electrical, piping,
etc.) properly to protect against moisture and weather.
