accessories shipped in the
cold water basin must be
removed prior to installation.
WARNING: Unless units ship
fully assembled, basin &
casing/roof deck sections
must be rigged separately.

The proper rigging sequence for the PCT series is to lift the basin
section(s) into place first. On multi-section basins lift each section into
place separately and then bolt sections together. Next, lift each casing
section into place and secure to the basin section. If motor(s) are
supplied loose fit the motors. At the completion of this stage a crane is
no longer required.
Finally securely bolt the unit to supporting steel and on multi-section
basins seal the joint between sections.
Table 1 gives the recommended dimensions for rigging each section of
any PCT unit. With the information from the table and the additional
instructions on the following pages the rigging of a PCT Cooling Tower
can be quickly accomplished.
