3.	EXECUTION

3.1	MANUFACTURER'S INSTRUCTIONS

A.	Compliance: Comply with manufacturer's product data, including technical bulletins, product catalog, and installation instructions.

3.2	EXAMINATION

A.	Examine areas to receive fans. Notify the Engineer of conditions that would adversely affect installation or subsequent utilization and maintenance of fans. Do not proceed with installation until unsatisfactory conditions are corrected.

3.3	PREPARATION

A.	Verify that the fan is to be installed in a location where the airfoils will be a minimum of 7 feet above the finished floor with a minimum of 3 feet of clearance to any obstructions. 
B.	If the building has a mezzanine or other elevated spaces that may be occupied by people, verify that no component of the fan can be reached from the highest level or deck. The fan must be positioned so that the tips of the airfoils are a minimum of 3 feet away from the furthest point that a person could extend an appendage outward. 
C.	If the fan is to be mounted in an area where materials or equipment may be elevated into its path, ensure that the floor is marked or painted to alert personnel of the overhead location of the fans.
D.	If the building is equipped with a fire sprinkler system, verify that the placement of the fan will not interfere with correct sprinkler operation and that the fan installation complies with all national, state and local codes. 
E.	Check to see if the intended placement of the fan is directly below any building lights or skylights. Avoid installing fans directly below a light source to prevent a strobing effect that can be caused by fan rotation. 
F.	For best performance, fans must be installed with a two fan diameter minimum clearance between the center of the fan and radiant heaters or HVAC system discharges or intakes.
G.	Verify that the mounting surface will bear the operating weight and maximum torque (twisting force) of the unit. The Structural Engineer of Record (SEOR) must perform a thorough evaluation of the mounting structure and determine all final mounting requirements before the fan is installed. 

3.4	INSTALLATION

A.	Install fan system as indicated in the Installation, Operation and Maintenance Manual (IOM) and contract drawings.
B.	Install fans in accordance with manufacturer's instructions.

3.5	SYSTEM STARTUP

A.	Refer to Installation, Operation, and Maintenance Manual (IOM).

3.6	CLEANING

A.	Clean as recommended by the manufacturer. Do not use material or methods which may damage finish surface or surrounding construction.

3.7	PROTECTION

A.	Protect installed product and finished surfaces from damage during construction.
B.	Protect installed fans to ensure that, except for normal weathering, fans will be without damage or deterioration at time of substantial completion
