Unpacking
Verify that all required parts and the correct quantity of
each item have been received. If any items are missing,
report shortages to your local representative to arrange
for obtaining missing parts. Due to availability of
transportation and truck space all items for the unit may
not be shipped together. Confirmation of shipment(s)
must be limited to only items on the bill of lading.
Handling
Lifting the fans must be done with care to avoid
damaging the housing. Fans are to be rigged and
moved by the optional lifting brackets provided or by
the skid when a forklift is used. Location of brackets
varies by model and size. Handle in such a manner
as to keep from scratching or chipping the coating (if
applicable). Damaged finish may reduce the ability of
the ventilator to resist corrosion.
