The Basic Model fan is designed for all-angle usage, it may be mounted in any position with air flow in one direction only - the fan may be specified for operation in "exhaust" or "supply" direction. These fans are shipped completely assembled, tested, and ready for installating. Check for transit damage immediately upon receipt and file a claim with the delivering carrier if damage is found. Also check for propellor alignment and free rotation. Make that equipment is adequately protected during on-site storage prior to installation.


  1. When mounted to a wall or other opening, the net inside dimension of the opening should be 1" more than fan blade size (see Dimension and Approval Drawings).

  2. SAFETY - Prior to start up, check installation for compliance with existing safety standards. Make sure that guards and/or other devices are in place as required to avoid accidental contact with rotating parts or hazards to personnel or critical equipment in the event of accidental rupture of the propeller.

  3. START UP - Before initial operation check:

    1. Free rotation and alignment of propeller.

    2. Circuit phase and voltage against motor nameplate and connection diagrams.

    1. Rotation ans air flow direction immediately upon start up for 3 phase motors only. If operating in the wrong direction, interchange any 2 leads.

    2. Vibration - if excessive, stop fan immediately and take corrective action.

  5. Fans must be operated within catalog performance data.


  1. CLEANING AND ADJUSTMENT - Provide for routine inspection of equipment. Clean off airborne materials that accumulate on the propeller and can cause vibration and/or reduce service life. Rust or corrosion on the propellor or fan structure should be cleaned throughly and protective finishes restored. On Belt Drive Units check belts for wear and tighten if required. When tightening belts use an ampere meter and be sure not to exceed motor plate rating.


    1. Sleeve Bearings - (have oil holes) for normal service, re-oil with a good grade SAE 20 machine oil every 6 months.

    2. Sleeve Bearings - (no oil holes) are factory lubricated fo the life of the motor.

    3. Ball Bearings - (No Grease fittings) Permanently sealed replace bearings, or clean and pack with proper grease every 5 years.
