Following Step #12A, remove the screws from along the top rear lip of the blower
cabinet panel. Slip the transition duct flange underneath the cabinet top edge and
loosely
insert two screws through the top edge, through the transition duct flange, and
into the cabinet end panel. Follow STEP #12B.
13)
If the transition duct has duct extensions (FIGURE 2, ITEM 9), insert the duct extension
mounting flanges into the slots on the cabinet end panel.
14)
With the transition duct attached to the cabinet, carefully tilt the transition duct upward
enough to clear the cooler reservoir pan and slide the evaporative cooling module
underneath the catch pad mounting trough. Squeeze the cooling module and transition
duct assembly into the system cabinet until a tight fit is obtained.
15) Following STEP #15, line up the holes in the cooling module corner leg with the holes in
the transition duct sides. Using five #10 x 1/2" long sheetmetal screws per side, fasten
the transition duct sides to the cooling moduler.
16)
Following STEP #16, fasten the transition duct top lip to the front top cover of the
cooling module with seven of the #10 x 1/2" long sheetmetal screws provided.
17) With the cooling module and transition duct properly positioned on the blower cabinet,
tighten the two screws loosely inserted in STEP 12B. Insert and tighten screws in the
remaining holes along top edge of cabinet.
NOTE: When attaching the transition duct to the cabinet (STEP 18 or 19), you may find
it easier with the media pads removed. See FIGURES 5 and 7 and the corresponding
