Inspection and Maintenance during Storage
Long-term storage is defined as storage for a period exceeding one month from the date the equipment was received. Fans and
motors should be stored in a dry, low humidity area indoors. Equipment which is to be installed, but not operated for several months,
should first be blocked to take the weight off of the vibration isolators (if provided) and then given the same protection, periodic
inspection and maintenance as a unit in storage. To prevent puddle corrosion of fan bearings that undergo long-term storage, the
following preventive maintenance must be performed:
1. Fan bearings must be re-lubricated every month until the fans are put into service. A clear 1/16” bead of grease must appear
on each side of the bearings. Fan wheels are to be rotated manually while the bearings are re-lubricated. Refer to the specific
bearing lubrication instructions located on the fan housing for the type of lubricant to use.
2. Motor bearings should be lubricated as recommended by the motor manufacturer.
Removing from Storage
Fans should be hoisted with slings placed around the fan housing. When a single hoist is used, a “spreader” will keep the sling from
slipping on the housing. Fans must be protected and maintained from the time of storage to the time of assembly and installation.
Ensure that the fan is in working order before assembly and installation. Be sure that no damage has occurred between storage and
time of assembly.
1. Ensure that all fasteners, fittings, screws, etc. are tightened to recommended specifications.
2. Make sure that no parts or objects are rubbing on the fan wheel as it is turned.
