Maintenance Information
Guy Wire Check (if applicable)
: Checking an EnergyLogic fan’s guy wires for tension and
inspecting for frayed sections could mitigate a problem before it occurs. The guy wires should
be under enough tension to prevent any movement in the motor unit or the extension tube. If the
motor can be moved by pushing on it, the guy wires need to be tightened. Fan owners should
confirm that the guy wires are not wrapped around any sharp edges. EnergyLogic recommends
attaching guy wires to the building with eye bolts or eye lags. If they are not already installed with
eye bolts or lags, we urge fan owners to install these in order to help keep the guy wires from
fraying. If guy wires are installed with turnbuckles, jam nuts should periodically be checked to
ensure tightness. If they are loose, the guy wire cables may need to be re-tensioned.
Airfoil Cleaning
: Depending on the type of commercial application the EnergyLogic fan is in,
there can be quite a bit of dust or other particulates that cling to the fan’s airfoils. While this
may not affect fan performance, we recommend fan owners keep airfoils clean by having a
maintenance person or skilled trade professional – who has experience using a lift – wipe the
fan airfoils with a rag or sponge using hot water or regular cleaning solutions. Please do not use
chlorine or any chemicals containing chlorine.
Safety Cable Check
: Each EnergyLogic fan comes with a safety cable. Depending on the fan
model, the safety cable either wraps around the building structure and the fan frame, or comes
out of the top of the fan and wraps around the building structure. The safety cable is an important
part of the safety system and acts as a last resort should an earthquake, collision, or similar
catastrophic event occur. As such, it’s vital for fan owners to ensure that it is intact and properly
secured.
Reverse Operation
: The beauty of EnergyLogic HVLS fans is that they are built to run in forward
and reverse mode. However, changing the direction of your fan can put initial stress on the fan if
it has not been properly checked. It is a good idea to make sure guy wires, safety cables and all
bolts and nuts are tight. Cleaning the fan before switching directions will prevent dust and other
particles from falling off the fan airfoils that are now turning in the opposite direction.
Maintenance Plan:
Things to look for include: properly torqued fasteners, rust, cracked welds, unusual noise, hub
migration/movement, guy wire loosening or movement.
Year 1-10:
One inspection on lift per year.
Year 11 and beyond:
Annual inspections from a lift and seasonal inspections both before and after the busy season
from the ground.
NOTE:
If there are issues or concern discovered during an inspection, please contact the service
and technical support department at EnergyLogic for help.
