Introduction; Method Of Shipment; Structural Steel Support - EVAPCO ATC-E Rigging And Assembly Instructions

ATC-E, ATC-ES, ATWB, eco-ATWB and eco-ATWB-E Evaporative Condensers and Closed Circuit Coolers

Introduction

This manual provides instructions and recommendations to safely and correctly install all ATC-E, ATC-ES, ATWB, eco-ATWB and eco-
ATWB-E Evaporative Condensers and Closed Circuit Coolers. It is recommended that all the instructions provided in this manual be
reviewed in detail prior to rigging and assembly. If at any point, specific circumstances not covered by this manual arise, please contact
your local EVAPCO representative for assistance.
Proper care must be taken by all parties involved in handling and assembling the equipment to ensure that safe and thorough
installation practices are implemented to prevent damage or injury to the equipment, persons and environment involved.

Method of Shipment

Induced draft coil products are shipped 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, self-tapping screws and any other required materials, are packaged and placed inside the pan for shipment. For
units consisting of multiple cells, drip channels and splash guards will ship loose in the basin for field installation.
For 7' and 8.5' (2.2 m and 2.6m) and 14' and 17' (4.3m and 5.2m) wide units, the motors and drives are factory aligned and then
shipped loose inside the basin section for mounting during installation. Refer to the "External Motor Installation" section in this bulletin.
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.

Structural Steel Support

Two structural " " beams running the length of the unit are required for support of each cell of the units. These beams should be
located underneath the outer flanges of the unit (See Table 1). Mounting holes 3/4" (1.9mm) in diameter are located in the bottom
flanges of the unit for bolting to the structural steel (See steel support print in unit submittal 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 to be
1/360th of the unit length, not to exceed 1/2" (13mm). Deflection may be calculated by using 55% of the operating weight of the
unit as a uniform load on each beam (See certified print in unit submittal for operating weight).
The supporting " " beams should be level before setting the unit. Do not level the unit by shimming between the bottom flanges
and the beams as this will not provide proper and continuous longitudinal support. Support beams and anchor bolts are to be
furnished by others. Always refer to the certified print in the unit submittal for unit weights, dimensions and technical data.
Please refer to the unit submittal for detailed, project specific steel support arrangement.
