Shi
pment
Forced draft units are shipped either fully assembled (small units) or with the top section(s) separate from the bottom section(s).
These sections have mating flanges and will join together in a waterproof joint when sealed and bolted together as described in the
following instructions. Miscellaneous items, such as sealer, fasteners and any other required materials, are packaged and placed
inside the pan for shipment.
NOTE: All casing sections are factory inspected prior to shipment to verify proper fit for rigging. Please take extra care to handle
and rig unit section per the instructions of this manual to avoid possible distortion and poor casing alignment. It is advisable to
check each section upon receipt and during each lift to ensure that the factory alignment has not been altered. Should the field
inspection indicate the section alignment (“square”) has been altered, please contact the factory or your local EVAPCO
representative for additional instructions to obtain proper section fit.
Storage
Do not place tarps or other coverings over the top of the units if the units are to be stored before installation. Excessive heat can
build up if the units are covered causing possible damage to the PVC eliminators. For extended storage beyond six months rotate
the fan and fan motor shaft(s) monthly. Also, the fan shaft bearings should be purged and regreased prior to start-up.
G
eneral
For extended lifts, or where hazards may exist, it is recommended that safety slings and spreaders be employed for safety. Refer
to the extended lift information in this bulletin.
International Building Code

The International Building Code (IBC) is a comprehensive set of regulations addressing the structural design and installation
requirements for building systems– including HVAC and industrial refrigeration equipment. As of June 2008, all 50 states plus
Washington D.C. have adopted the International Building Code. The code provisions require that evaporative cooling equipment
and all other components permanently installed on a structure must meet the same seismic design criteria as the building. The LS
Series Coolers and Condensers are IBC 2006 compliant up to 1g (7kPa wind-load) with standard construction and up to 5.12g
(7kPa wind-load) with additional structural modifications.
All items attached to the Evapco LS Closed Circuit Cooler or LS Evaporative Condenser must be independently reviewed and
isolated to meet applicable wind and seismic loads. This includes piping, ductwork, conduit, and electrical connections. These
items must be flexibly attached to the Evapco unit so as not to transmit additional loads to the equipment as a result of seismic or
wind forces.
Structural Steel
Suppor
t
Two structural “I” beams running the length of the unit are required for supporting the unit. These beams should be located
underneath the outer flanges of the unit as shown in Figure 1. See Table 1 for Steel Support Dimensions.
Mounting holes, 19mm in diameter, are located in the bottom flange for bolting to the structural steel. Refer to the recommended
structural steel support drawing and certified print for exact bolt hole location. Bolt the bottom section to the steel support before
rigging the top section.
Beams should be sized in accordance with accepted structural practices. Maximum deflection of the beam under the unit should be
1/360 of the unit length, not to exceed 13mm. Deflection may be calculated by using 55% of the operating weight as a uniform load
on each beam (see certified print for operating weight).
