Fan Installation
Fan Housing Installation
Lines of attachment are to be lifted in the vertical direction to prevent damage. Spreader bars
are recommended.
Lifting lugs located on the four corners of the base
If the windband is shipped attached to the fan housing or if the windband is secured to the fan housing prior to mounting to the plenum, the fan / windband assembly should be lifted by the lifting lugs located on the fan housing. Do not lift this assembly by the lifting lugs located on the windband. Connect fan to plenum using Excelon™ flex connector found in the
Fan Stack Installation
**Guy wire attachments 
Stack Extension 
Fan Assembly
If fan requires a stack or stack extension, install on fan before installing nozzle and windband. Place gasketing between any sections, blower housing and initial stack. Use lifting lugs to position each piece into place. Attach stack or stack extension to blower housing using 316 stainless steel bolts (provided) through flanges aligning bolt patterns. Use anti- seize gel (provided) to prevent galling/welding of all stainless steel fasteners.
Greenheck strongly recommends the use of guy wires on any system that incorporates the usage of a stack extension including inline attenuators. Subsequent guy wires are to be designed and installed by others.
