PHC PARALLEL HYBRID EVAPORATIVE CONDENSERS
Method of Shipment
PHC-E condensers are shipped with the top section(s) separate from the bottom section(s). These sections have mating flanges and
will join together in a waterproof joint when sealed and bolted together as described in the following instructions. Miscellaneous items,
such as sealer, fasteners and any other required materials, are packaged and placed inside the pan for shipment.
Storage
Do not place tarps or other coverings over the top of the units if the units are to be stored before installation. Excessive heat can build
up if the units are covered causing possible damage to the PVC crossflow fill and eliminators. For extended storage, rotate the fan and
fan motor shaft(s) monthly. Beyond six months, the fan shaft bearings should be purged and regreased prior to startup.
General
For extended lifts, or where hazards may exist, it is recommended that safety slings and spreaders be employed for safety .
Refer to the “Extended Lifts” section in this bulletin .
NOTE:
All casing sections are factory inspected prior to shipment to verify proper fit for rigging. Please take extra care to handle
and rig unit sections per the instructions of this manual to avoid possible distortion and cause poor casing alignment. It is advisable
to check each section upon receipt and during each lift to ensure that the factory alignment has not been altered. Should the
field inspection indicate the section alignment (“square”) has been altered, please contact the factory or your local EVAPCO sales
representative for additional instructions to obtain proper section fit.
Structural Steel Support
PHC-S-E
Two structural I-beams running the length of the unit are required for supporting the unit. These beams should be located underneath
the outer flanges of the unit. (See
Figure 1
)
PHC-D-E Models
Three structural I-beams running the width of the unit are required for supporting the unit. Locate two beams underneath the outer
flanges of the unit and locate the third beam laterally along the center of the unit. (See
Figure 2
)
All Models
Mounting holes, 3/4” (19 mm) in diameter, are located in the bottom flange for bolting to the structural steel. Refer to the
recommended structural steel support drawing and certified print for exact bolt hole location. Bolt the bottom section to the steel
support before rigging the top section.
Beams should be sized in accordance with accepted structural practices and the local building code regulations. Maximum deflection
of the beam under the unit is recommended to be 1/360 of the unit length, not to exceed 1/2” (13 mm). Deflection may be calculated
by using 55% of the operating weight as a uniform load on each beam (see certified print for operating weight).
The supporting I-beams should be level to within 1/8” (3 mm) in 6’ (1.8 m) before setting the unit. Do not level the unit by shimming
between the bottom unit flange and the beams as this will not provide proper longitudinal support.
