GENERAL INFORMATION
•
The optional evaporative cooling module for packaged indirect-fired system models RGBL, RPBL, SSCBL, PGBL,
blower cabinet model RBL, and direct-fired makeup air models ADF/ADFH 700/1200 is factory-assembled but
requires field-installation.
•
The evaporative cooling module is available in the following options:
Option
AS3:
includes 6-inch rigid cellulose media
Option AS4:
includes 12-inch rigid cellulose media
Option AS5:
includes 6-inch rigid glass fiber media
Option AS8:
includes 12-inch rigid glass fiber media
•
The base parts for supporting the evaporative cooling module and the transition duct for connecting it to the unit
are shipped with the module for field-assembly and installation. If optional moisture elimination pads, a drain and
fill kit, and/or a water hammer arrestor are to be included in the installation, they also require field-installation.
•
All evaporative cooling modules require outside air.
