4. Operation and Maintenance

4.1 Operation

1. INITIAL START-UP: With electrical power off, verify that the fan propeller turns freely and that all fasteners are secure. Turn on electrical power and confirm that the fan operates smoothly.
2. ADJUSTMENTS: Set the fan control to the temperature shown on your Aerotech ventilation system drawing, or to a value which will provide the desired environmental conditions.

4.2. Maintenance

The following inspection and cleaning procedures should be performed monthly:

Tools Needed for Maintenance:

wrenches: 10mm, 13mm, 16mm, 17mm, 27mm, 1/2", 6mm Hex

1. INSPECT PROPELLER: Check that propeller is secure on drive hub and that there are no signs of damage. The blades are of a self-cleaning design and should not require maintenance.
2. CLEAN regularly for best results:
   • FAN MOTOR: Remove any dust accumulation from motor using a brush or cloth. (DO NOT use a pressure washer). A clean motor will run cooler and last longer. At the same time, verify that the motor is secure in its mount.
   • DAMPER: Carefully clean dust from damper door and frame so that damper door opens and closes freely. A brush or cloth should be used.
   • GUARD: Clean any dust or feathers from fan guards using a brush. Dirty guards can reduce airflow.
3. CHECK FASTENERS: For safety, all fasteners should be inspected. Tighten any loose connections.
4. INSPECT FAN CONTROL: With power disconnected, inspect all electrical connections. Wiring should be secure and in good condition. Remove any dust build-up from control case and sensor using a soft brush or cloth. NEVER CLEAN ELECTRICAL EQUIPMENT WITH A PRESSURE WASHER!

WARNING: Disconnect Power Before Servicing. Moving Parts, Disconnect Power Before Servicing.

6. Winterizing

6.1 Winterizing

In most climates, it is probable that the ventilation system will never need to operate at a total capacity during the colder winter months. Consequently, it is advisable to “winterize” those fans which will not be used in cold weather to avoid unnecessary heat loss and condensation.

To winterize, turn fan control “off”. Install the insulated closure panel over the fan intake. If you don't have an insulated closure panel, a piece of rigid insulation material can be used. Remember the insulation panel must be removed before warmer weather returns.

NOTE: At least one single speed fan should be left uncovered and with power available to provide air movement in the event of variable speed control difficulties.

6.2 Winter Weather Protection

To prevent cone or fan damage from snow or ice sliding off building roof, weather protection must be provided. A weather shelter may be constructed to cover the entire fan, See Figure 17, or snow guards may be placed on the roof, See Figure 18.

A diagram illustrates a weather shelter over fans.
