A MegaFan fan should never be run without a properly installed safety cable which is supplied with every fan along with all required hardware You must install safety cable for waranty to be in effect Page 8 Issue 1 July 15 2009 2 4 Close Clearances The area within 900mm of the blade tips when the fan is at rest is considered close clearance It is EXTREMELY DANGEROUS to mount the fans within close clearance of any object We strongly recommend not mounting the fan closerthan 15 of its diameterto any object If this is an issue mounting extensions and smaller fans are available from MegaFan 2 5 Guy Cables A running fan can sway due to a minor imbalance or because of wind Wind may be only the air movement the fan itself generates or it may be actual wind if the fan ismounted outdoorsor in open areas Since the mounting system is free swiveling it will not stop fan movement so it isimperative that guy wires be property installed The primary considerations are angle and tension of the guy wires See Step 10 for more information 2 6 Guards If there is potential for people orobjectsto come in contact with a running fan itisbestto constructa guard from angle iron and steel mesh attaching it securely to the building structure The guard should be mounted with sufficient clearance so that no part of itcan be pushed into the fan with at least 450mm of clearance on all sides We recommend 50 x 50 x 4mm angle iron
4. Simply wipe down the outside of the enclosure with a cloth or duster periodically if desired Power Unit The gearbox is lubed for life and we use thread locking compound on critical nuts and bolts However it isa good idea to occasionally check that no nuts or bolts have vibrated loose No other maintenance is required Mounting Hardware Checkall mounting bolts annually to be sure they have not loosened Also check the safety cable and guy wiresto be sure they are not loose or frayed Loose guy wiresare more likely to break than tight ones and broken guy wires may fall into the fan If a guy wire is loose carefully check to be sure it is not damaged and re tighten it Page 10 Issue 1 July 15 2009 2 Installation Procedures Step 1 Install mounting hardware For steel I Beam installations mount so that the large plate isagainstthe bottom of the beam Be sure the plate isat a 90 degree angle to the beam and centered Place the supplied clampson top ofthe beam and attach them to the mount using the supplied fasteners Forthickerl beams use the supplied shims between the clamp and the mount as shown below SRREEETINITET 11 07 Note In all cases be sure to thoroughly tighten all mounting bolts and nuts The nylon lock nuts help prevent loosening due to vibration but there is no substitute for proper tightening We recommend that nylon lock nuts not be removed and reused because this will defeat the nylon locking instead
