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 Vektor-CD hardware kit.

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.

(provided) through support brackets welded to the inside of the windband. Use anti-seize gel (provided) to prevent galling / welding of all stainless steel fasteners.

Bypass Air Plenum Installation

Span determines the number of lifting lugs to be used during installation:

	Lifting lugs located at top	Span
	of bypass air plenum	Span
	of bypass air plenum

Span	No. of Lifting Lugs

12 inches or less	Minimum of 4 lifting lugs

12 to 18 inches	Minimum of 6 lifting lugs

18 inches or greater	Minimum of 8 lifting lugs

Guy Wire Locations

1-1/4 inch thru-hole typical

NOTE: Guy wires to be supplied by others. Fastening to building structure to be provided and engineered by others.

If your fan requires stack extensions, the use of guy wires is recommended. See drawing for guy wire connection locations.

Note: Keep 36 inches minimum spacing around unit to provide adequate clearance for servicing or repairing unit.
