Receive and inspect fans for defects. All defective or damaged fans shall be replaced at no cost to the Owner. Openings shall remain protected during storage. Immediately after installation and assembly, all factory protection shall be restored. Unit shall remain protected until just prior to final acceptance by Owner. Use spreader bars on lifting cables when hoisting fans from lifting lugs to prevent cable damage to housing or components. Rig fans per fan manufacturer's recommendations. Fans shall be installed as shown on drawings, in accordance with details, approved submittals and the fan Manufacturer's installation requirements and recommendations. Ensure fans are installed to allow easy accessibility for service or removal of fan components. Provide and install supplemental steel, supports, isolators and hangers necessary to hang or mount fans. Coordinate final location and placement of intermediate steel and ductwork connections in field. Install suspended fans with supports attached to structural members. Install any associated motors, drives, or components that have been shipped loose. Fan shall be installed, made fully operation, and tested. Install flexible inlet and discharge couplings to prevent vibration transmission to ductwork. Inlet and discharge ductwork shall have a minimum straight run of two (2) fan diameters upstream and downstream of the fan. Just to final acceptance fan shall be thoroughly cleaned of all grease, dirt, and dust, etc. Apply touch-up paint or touch-up coating after final cleaning to repair any damage to the finish. Provide or coordinate the scope of work associated with the installation of fans as specified in the following sections: Roof curbs Concrete Housekeeping Pads Vibration isolation Sheet Metal accessories Interconnection wiring and conduit from power source to fan connection (starter). Perform the following and inspections prior to fan operation: Verify that shipping, blocking, and bracing are removed. Verify that unit is secure on mountings and supporting devices, and that connections to ducts and electrical components are complete. Verify that proper thermal-overload protection is installed in motors, starters, and disconnect switches. Verify that cleaning and adjusting are complete. Inspect fan scroll for debris or Remove guards. Align and adjust belt tension, verify that fan wheel and motor rotate freely, and that bearing operation is smooth. Re-install belt guards.
