Figure 5.  Media Pad Assembly

2.  Install moisture elimination pads if required (see 

Figure 6

):

a.  Install two catch pad clamps to one side of cooling module’s front legs and secure clamps through legs into 

clamp using four screws (8).

b.  Assemble catch pads together using three screws (8).

NOTE:  The screen part of the catch pad assembly should always be facing the attached air mover.

c.  Guide catch pad assembly through inlet of cooling module and place bottom of lower pad into catch pad mounting 

trough (see 

Figure 4

). Slide catch pad assembly into two slots located in catch pad clamps installed in step 2a.

d.  With pads in place, slide one of two remaining clamps over middle seam where assembled catch pads meet. 

Slide other clamp over top catch pad frame and secure both clamps to cooling module leg using screws (8).

⚠ CAUTION ⚠

IMPORTANT: Cooling media is made up of two different sheets of cooling material, each with 

its own unique angle. When replacing the cooing media, BE CERTAIN that the 45° angle slopes 

downward toward the incoming outside air. If the media is not installed properly, water blowoff 

from the media pads will occur.
