General Maintenance Suggestions
The Concrete Block Exhaust Fan requires very little
maintenance. However, since small problems left
unchecked over time could lead to loss of performance
or early motor failure, we do recommend that the unit be
inspected periodically (once or twice a year).
The fan motor and wheel(s) should be checked for dust
and dirt accumulations. Dirt buildup can lead to loss of
performance and motor overheating. Cleaning can be
accomplished by brushing off any dust or dirt that may
have accumulated.
Service and Maintenance:
1. Turn off all power to Concrete Block Fan.
2. Remove (2) grille screws with Phillips head
screwdriver. Figure 1.
3. Unfasten (4) blower panel screws from support
angles. Figure 2.
4. Pull blower assembly out approximately 12 inches.
5. Reach inside housing and unplug receptacle from
junction box.
6. Brush off any accumulated dust or dirt from the fan
motor and wheel(s).
