PMC & eco-PMC SERIES FORCED DRAFT EVAPORATIVE CONDENSERS
Optional Straight-Sided Hood Section
Some units may be supplied with an optional discharge hood section. This section will ship from the factory as a separate item or loosely
mounted on top of either the basin and fan section or casing section to reduce freight charges. Each hood section is equipped with
U-bolts located at the four corners for lifting and final positioning (
Figure 14
). Always use safety slings for extended lifts or where any
hazard exists.
NOTE:
When combined with other sections, the hood must be removed prior to any lift. In all cases the hood section must be rigged
as a separate part.
Once the casing section has been secured to the basin and fan section, wipe the top flanges to remove any dirt or moisture. Place sealer
tape over the mounting hole centerline on the side flanges. Apply two strips of sealer tape, one partially overlapping the other, on the
end flanges as shown in
Figures 5
and
6
. Remove any shipping blocks or other obstructions. Lower the hood onto the top flange of the
casing section.
Install the retainer clips in all four corners as shown in
Figure 14
. For 18-foot-long hoods, two (2) additional clips are provided and are to
be fastened in the middle of each side.
NOTE:
Always lift the hood separately and follow the rigging sequence shown.
