NOTE: If the motor and fan have not been operated in the last (4) four weeks or more, lubricate all the bearings and rotate the motor and fan 

monthly to prevent moisture from accumulating in the bearings. (See Form 50.20-NM3, Long Term Storage)

ADJUSTMENT FOLLOWING INSTALLATION

The following adjustments should be made after 
installation:

• Blower Speed Adjustment

  Adjustment of blower speed is made by loosening 

the set screw in the outer (movable) pulley face 
and turning this face half or full turns only, so that 
the adjusting set screw will be positioned precisely 
over the fl at on the pulley hub.  Speed is reduced by 

adjusting the pulley faces so that they are further 
apart; speed is increased with faces closer together.  
Check all of the pulleys’ set screws for tightness.

• Room Thermostat

  Adjust room thermostat to desired temperature.  

This depends upon the environment and the 
individual.  For peak load conditions, the ideal 
thermostat setting for “winter” and “summer” is 
72°F and 76°F respectively.
