The V-belt drive components, when supplied by Greenheck Fan Corporation, have been carefully selected for this unit's

INSTALACION CON TRANSMISION POR BANDA V
1. Remove the protective coating from the end of the fan shaft and assure that it is free of nicks and burrs.
2. Check fan and motor shafts for parallel and angular alignment.
3. Slide sheaves on shafts - do not drive sheaves on as this may result in bearing
damage.
4. Align fan and motor sheaves with a straight-edge or string and tighten.
5. Place belts over sheaves. Do not pry or force belts, as this could result in damage to
the cords in the belts.
6. Adjust the tension until the belts appear snug. Run the unit for a few minutes (see
section on unit start-up) and allow the belts to "Set" properly.
7. With the fan off, adjust the belt tension by moving the motor base. (See belt
tensioning procedures in the maintenance section of this manual). When in operation,
the tight side of the belts should be in a straight line from sheave to sheave with a
slight bow on the slack side.
