What kind of maintenance do the fans require?
(A) Depending on the environment, the blades should be cleaned once or twice a year. It is recommended that, once a year mechanical connections be checked for proper tension. This also includes electrical connections in the fan controller and motor. It is recommended the oil level in the gear reducer should be checked once a year. In most cases the level should be within tolerances level but this is dependant on heat levels and time of operation.
