  1. Blowers are designed for all position mounting. Sleeve bearing models, however, must be installed with oil ports facing upward.
  2. Connect the blower leads to the appropriate power source. Refer to blower nameplate.
  3. WARNING: A ground wire must run from the blower motor housing (bare metal) to a suitable ground, such as a properly ground metallic raceway or ground wire system. Insulate unused lead wires individually.
  4. These blowers are not recommended for use with any type of speed control devices.

The motor bearings should be relubricated every 6 months with 10 to 20 drops of SAE 10W or 20W nondetergent oil (ML-type) or electric motor oil with the following exceptions:

  • The C-frame motor is lubricated at the factory and requires no further lubrication.
  • Sealed ball-bearing units show oil ports, however, do not require further lubrication.
  • High temperature blowers are lubricated at the factory and require no further lubrication. However, at higher inlet temperatures, increased bearing life can be achieved by relubricating every 6 months with 10 to 20 drops of Anderol #465 high temperature synthetic lubricant. DO NOT use petroleum base oil, as bearing failure will result.

Common Recommendations:
Always disconnect and lock out power supply before servicing the blower or working with the unit for any reason. This is especially important with blowers equipped with automatic reset thermal protection. Blower motor may activate without warning!!!
