1. CAUTION! This fan contains rotating parts and requires special service. Appropriate safety precautions should be taken during installation, operation and maintenance. 2. WARNING! Do not install or operate this fan in an environment or atmosphere where combustible or flammable materials, gasses or fumes are present, unless it was specifically designed and manufactured for use in that environment.
Lock out the power source before the installation of all accessories. Fan electrical power can now be applied and special attention should be given to determine if motor is working properly. At this time, with air system in full operation, with guards attached, it is well for the electrician to measure the operating amperage of the motor and compare with the nameplate rating to determine that the motor is operating under safe load conditions.
BEARINGS AND LUBRICATION: All S&P belt drive fan bearings are heavy duty, self-aligning ball type and are relubricable for continuous service. Selection of the correct bearing grease and greasing intervals depends on several things. Extreme high or low temperatures, dirty or damp surrounds, and vibration exceeding 1 or 2 mils are all things that will require more frequent greasing or special greases.

V-BELTS: V-belts on S&P belt drive fans are oil, heat and static resistant type, and oversized for continuous duty. With proper installation and maintenance, years of operating efficiency can be added to the life span of the V-belt drive. The condition of V-belts and the amount of belt tension should be checked prior to start-up and at 800 hours. Belt Tension should be checked once a year after the 800 hour check.
