Maintenance
IMPORTANT! Disconnect Power Prior To Maintaining Or Cleaning The Fan. The fan may start automatically causing
serious injury or death.
• Service and repair of fans should be done only by a qualified technician.
• Minimize contact of moisture or corrosive chemicals to the surfaces of the fan components to maximize fan life.
• After washing fans, operate fans long enough to remove moisture from all fan surfaces.
• Keep the fan clean for maximum life and best performance. Do Not spray water on the Fan Shaft Bearings, the Belt
Tensioner, or the Motor.
• Periodically check the V-Belt and replace if necessary. A worn Belt will cause a substantial drop in Fan performance or
it can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the belt. (See below)
• Check Belt Tension. The Belt should be tensioned just tight enough to minimize Belt
slippage. Over tensioning the belt will cause
premature Belt and Bearing wear.
• The Alignment Mark on the Tensioner Base
should be lined up with the 1st line on the
Idler Support Bracket.
• Check Sheaves for wear. Replace if a Sheave groove is worn.

Grease Zerk
Grease Zerk
Fan Bearing and Belt Tensioner Lubrication
• Grease zerks are provided for lubrication on the fan shaft bearings and the belt tensioner.
• Lubricate the fan every 2-6 months or whenever these components get wet.
• Disconnect power to the fan before lubricating.
• Clean the zerk before lubricating to prevent contamination from entering the bearing.
• Use a high quality lithium based, NLGI #2, grease such as Shell Gadus S2 V100 2. Do not use incompatible greases
containing aluminum, barium, calcium, bentonite clay or polyurea thickeners.
• Slowly rotate the fan shaft by hand while slowly applying the grease. Rapidly applying grease to a stationary bearing
can damage the bearing seals.
• Apply about .10 oz (2.8 g, 3.1 cc) of grease at a time or until a slight amount of grease can be seen purging from the
seal.
