Rigging
The unit should be lifted using all marked
lifting points. Spreader bars should be used
to prevent damage to the unit. They should
be at least 12 inches wider than the unit to
prevent damage. Be sure that the protruding
coil connections are not interfering with the
straps.
Figure 3 - Unit Lifting Example
Only two lifting points on each side of the
unit should be connected to one spreader
bar, and the straps, chains or cables
connected to a single spreader bar should be
the same length. The angle of each strap
should be a minimum of 60° from horizontal
to prevent excess lateral force on the lifting
points.
All shipping covers should be left in place
until ductwork is ready to be connected or
shipping sections are ready to be joined.

Module Location
Module location is identified by a three digit
number which is labeled on the access side
of the base rail. The last two digits in the
location number are an incremental number
for the position.
The numbering begins at the return air side
of the unit. Module 101 will always be the
bottom module at the return air end of the
unit.
Check the shipping section weights
on the Bill of Lading to be sure they
can be lifted safely. Rigging should
be adjusted so that all sections are
lifted level.
