2.- INSTALLATION

2.4.- UNIT LOCATION AND WEIGHT DISTRIBUTION

The bedplate is made up of three galvanized metal channels, capable of withstanding the weight of the units
whether hung from the ceiling or mounted on the floor.
If the unit is floor mounted, then the profiles should be isolated with shock absorbing material such as anti-vibration
or pads. If used, consult the weight distribution table below to make the correct selection. Keep in mind that fans
rotate at approximately 850 rpm.
If the unit is hung, M-10 threaded rods should be used along with shock absorbing ceiling supports.
