Pre-Installation Checklist - Bigass 4900 Manuel D'installation

PRE-INSTALLATION CHECKLIST

A structural engineer approved the mounting structure.
The mounting structure must be able to withstand the torque forces generated by the fan. The fan
generates up to 120 ft·lb (162.7 N·m) of torque during operation.
I am familiar with the function of the safety cable.
The fan will be installed so that the airfoils are at least 10 ft (3.05 m) above the floor.
The fan will be installed so that the airfoils have a minimum of 2 ft (0.61 m) of clearance from
obstructions and the building structure.
The distance of the fan from the ceiling should be measured from the top of the winglets to the
ceiling.
The fan will be installed so that it is not subjected to high winds such as from an HVAC system
or near a large garage door.
If the fan is mounted at the same level or higher than a diffuser, the winglets must be at a distance
that is at least 1x the measure of the fan's diameter. If the fan is mounted at the same height or
below a diffuser, the winglets must be at a distance that is at least 2x the measure of the fan's
diameter.
The distance between multiple fans will be at least 2.5x the fans' diameter when measured
from the centers of the fans.
The upper mount is the correct size for the I-beam.
The airfoils and other fan components are those that were shipped with the motor unit.
If installing multiple fans, do not mix and match fan components.
The supply power circuit is appropriate for the Variable Frequency Drive (VFD), and power
wiring is routed to the site of the fan and VFD.
See the specification label on the fan or consult the Technical Specifications section for power
requirements.
