PHC PARALLEL HYBRID EVAPORATIVE CONDENSERS
Applying Sealer Tape
Once the bottom section has been set on the supporting steel and bolted in place, wipe the top flanges to remove any dirt or moisture.
Place sealer tape over the mounting holes centerline on the side flanges. Apply two strips of sealer tape, one partially overlapping the
other, on the end flanges. The sealer tape should overlap on the corners as shown in
Figure 6
. Do not splice the sealer tape along the
end flanges and preferably not on the side flanges if it can be avoided. Always remove the paper backing from the sealer tape.
Rigging Coil / Fan Section
Four lifting ears are provided in the upper corners of the coil / fan sections for lifting. Sections 24’ (7,3 m) or longer will have two
additional lifting ears in the middle of the section (See
Figures 7
and
8
).
CAUTION: USE ALL LIFTING EARS PROVIDED ON THE SECTION. A SPREADER BEAM MUST BE USED FOR
LIFTING THE TOP SECTION(S) AS SHOWN IN FIGURES 7 and 8!
The bottom of the spreader beam must be a minimum dimension
“H” above the lowest lifting ear to prevent undue strain on the
lifting ears and the section structure. The weight is not evenly
distributed across the width of the coil/fan section. Therefore,
the top connection of the spreader beam will need to be offset
towards the coil side to balance the load. The location of this
connection will vary based on the unit configuration.
See
Table 3
for the “H” and “W” dimensions. These lifting devices
should not be used for extended lifts or where any hazard exists
unless safety slings are employed under the section.
(See “Extended Lifts” for proper arrangement)
