Preparing The Work Site - BIG ASS FANS Essence Installation Manual

Preparing the work site

The fan should only be installed according to the instructions described in this manual. Consult a structural
engineer for installation methods not covered in this manual. For optional mounting methods, refer to the installation
instructions included with the fan parts.
When surveying the work site, keep the following mechanical and electrical guidelines in mind.
Mechanical
• A suitable means for lifting the weight of the fan, such as a scissor lift, and at least two installation personnel will be required.
• If hanging the fan from angle irons, the minimum dimensions of the angle iron must be 2-1/2'' × 2-1/2'' × 1/4''
(6.4 cm × 6.4 cm × 0.6 cm) and it cannot be longer than 12 ft (3.6 m). It must be secured to the structure. Do not mount the fan to a
single purlin, truss, or bar joist. Consult a structural engineer for installation methods not covered in this manual.
• To reduce the risk of injury to persons, install the fan so that the airfoils are at least 10 ft (3.05 m) above the floor.
• If mounting the fan in the vicinity of an infrared/radiant heater, it is recommended that the fan be mounted outside of the clearances
recommended by the manufacturer of the heater and at a height equal to or above the shielding on the heating element with the
controller on the opposite side of the heater. If mounting the fan below the heater shielding, all fan elements must be outside of the
clearances recommended by the heater manufacturer. The installation manual for the specific model of heater will typically provide
the minimum clearance to combustibles (MCC).
• Adhere to the safety requirements in the table below when selecting where to mount the fan.

Electrical
• Ensure power wiring is routed to a junction box at the fan location prior to installation.
• Essence is shipped with either a 110–125 VAC motor or a 200–240 VAC motor. The fan's voltage is marked on the fan packaging
®
and on the label on top of the main fan unit. The voltage cannot be changed during installation. Ensure your fan is the correct
voltage prior to beginning installation.
• Do NOT install the wall controller (wired or wireless) outdoors or in a location where it may come into contact with water.
• To optimize communication between the wireless wall controller and the fan(s), Big Ass Fans recommends installing the wireless
wall controller in a plastic junction box.
• To reduce the risk of electric shock, wiring should be performed by a qualified electrician! Incorrect assembly can cause electric
shock or damage the motor and the controller!
• Installation of a Big Ass Fan must be in accordance with the National Electrical Code (NEC), ANSI/NFPA 70-2011, and local codes.
• Do not install the wall controller if installing SmartSense. See the SmartSense Installation Guide for wiring and operating instructions.
