Installing Watertight Partitions & Firewalls - EVAPCO ATC-E Rigging And Assembly Instructions

ATC-E, ATC-ES, ATWB, eco-ATWB and eco-ATWB-E Evaporative Condensers and Closed Circuit Coolers
Installing Watertight Partitions & Firewalls
In some cases, a multi-cell unit is ordered with watertight partitions to allow for independent cell operation. To correctly assemble the
upper sections to the bottom sections, access to the rigging seams in between cells is necessary. To facilitate with this access, the
upper watertight partition is shipped loose for installation in the field. Figure 17 below provides instruction to install these in the field.
Note: The below instruction and arrangement also applies for Factory Mutual (FM) Approved multi-cell units, in which
case these partitions will be referred to as firewalls.
