The PMC SERIES FORCED DRAFT EVAPORATIVE CONDENSERS should be
rigged and assembled using the instructions and recommendations
outlined in this bulletin.
All personnel should review these procedures, as well as the latest industry-approved
Installation practices, prior to rigging and assembly. The information in this bulletin is
for informational purposes only. These instructions do not purport to cover all variations
and possible contingencies in connection with installation. Additionally, the procedures
described therein are subject to change without prior notice, due to EVAPCO, Inc.’s
ongoing research and development.
EVAPCO, Inc. makes no representations or warranties with respect to these instructions
or the products described herein. Nor shall EVAPCO, Inc. be responsible for any loss or
damage (direct, indirect, consequential, or other) during installation or handling of
equipment after shipment.

Method of Shipment
Forced draft units are shipped either fully assembled (small units) or with the coil section(s) separate
from the basin/fan 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, self-tapping screws 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 each 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 startup.
General
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 Provisions
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. Since 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 PMC-E condensers are compliant with the latest IBC codes.
All items attached to the EVAPCO PMC-E 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 Support
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, 3/4”(19mm) in diameter, are located in the bottom flange for bolting to the struc-
tural steel. Refer to the recommended structural steel support drawing and certified print for exact
bolt hole location. Bolt the basin/fan section to the steel support before rigging the coil 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 1/2”(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).

The supporting I-beams should be level to within 1.5mm in 1m before setting the unit. Do not level
the unit by shimming between the bottom flange and the beams as this will not provide proper
longitudinal support.
NOTE: Consult the latest version of the IBC code for required steel support layout and structural
design.

Rigging the Basin/Fan Section —Standard Lift
U-bolts or similar lifting points are located in the basin/fan section for lifting and final positioning
purposes as shown below in Figures 2 and 3. Units with lengths up to 6m have 4 total lift points.
Units with lengths over 6m long units have either 6 or 8 lift points. See Table 2 for the minimum
“H” dimensions for rigging the basin/fan assembly. Always use safety slings for extended lifts or
where any hazard exits. See the “Extended Lifts” section in this bulletin.
NOTE: Use all of the U-bolts or lift points provided for lifting.
