Recommended Maintenance 1. Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary. 2. Fan impeller may accumulate lint. Periodic inspection, based upon dryer usage, should be performed to ensure that the fan impeller is not obstructed or loaded with lint. Under normal conditions, fan should be inspected a minimum of every Six (6) Months. Note: Excessive booster fan noise or vibration may be an indication of lint buildup on the impeller.
