Carefully read this publication prior to installation. Carefully inspect the fan and accessories for any damage and shortage immediately upon receipt of the fan. Checklist: 1. Turn the wheel by hand to ensure it turns freely and does not bind. 2. Inspect dampers (if included) for free operation of all moving parts. 3.
CBI Series Maintenance The CBI motors have sealed ball bearings and are permanently lubricated, requiring no maintenance. The impeller (fan wheel) and housing should be cleaned periodically to remove any dirt or other build up that may occur. Caution Always turn off the power before attempting any work or maintenance on the unit. If the utility blower housing and impeller require rinsing to clean, a drain plug may need to be installed to drain collected water from the housing. Motors are not washdown duty.
