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.
Lifting points may not be symmetrical to the center of gravity of the unit.
Ballast or unequal cable lengths maybe required.
Use all lifting points. Improper lifting can cause injury, death, and property
damage.
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.

Rigging and Handling

Cabinet Weather Protection
Transportation, rigging, or maintenance can damage the unit's weather seal.
Periodically inspect the unit for leakage. Standing moisture can promote
microbial growth, disease, or damage to the equipment and building.
This unit ships from the factory with fully gasketed access
doors and cabinet caulking to provide weather resistant
operation. After the unit is set in place, inspect all door gaskets
for shipping damage and replace if necessary.
Protect the unit from overhead runoff from overhangs or other
such structures.
Re-caulk field assembled options such as external piping or
vestibules per the installation instructions provided with the
option.
Lifting Brackets
Lifting brackets with 2ʺ (51 mm) diameter holes are provided
on the sides of the unit.
Cabling
• Dedicated Cables from each lift connection point to
spreader bars are required.
• No Looped Cables, Pulleys or other "self-leveling" riging
methods are allowed as the can cause excessive flexing
and damage
• Mid-Point connection points receive two cables each or a
dedicated spreader bar can be used instead.
• The Cable length from the spreader bar to the hook
should always be longer than the distance between the
outer lifting points
Spreader Bars
• Perpendicular spreader bars should be used for each lift
point.
• A Longitudinal spreader bar along the length of the unit
is required for units with more than 6 lift points to limit the
cable angles and the reuslting stress on the unit structure.
• Spreader bars should be at least 96ʺ to 100ʺ (2438 to
2540 mm) wide to prevent damage to the unit cabinet.
If the unit is stored at the construction site for an intermediate
period, take these additional precautions:
1. Support the unit well along the length of the base rail.
2. Level the unit (no twists or uneven ground surface).
3. Provide proper drainage around the unit to prevent
flooding of the equipment.
4. Provide adequate protection from vandalism, mechanical
contact, etc.
5. Securely close the doors and lock the handles
6. If there are isolation dampers, make sure they are
