Storage
If the fan is stored for any length of time prior to installation, completely coat the bearings, (if the fan has pillow-block bearings),
with grease or moisture inhibiting oil (refer to Lubricants on page 8). Rotate the wheel several revolutions every three to five
days to keep a coating of grease on all internal bearing parts.
Outdoor Storage
To maintain good working condition of the fan when it is stored outdoors, follow the additional instructions below.
1. Cover the outlet to prevent the accumulation of dirt and moisture in the housing.
2. Periodically rotate the wheel and operate dampers (if supplied).
3. Periodically inspect the unit to prevent damaging conditions.
Personal Safety
Disconnect switches are recommended. Place the disconnect
switch near the fan in order that the power can be swiftly cut
off in case of an emergency, and in order that maintenance
personnel are provided complete control of the power source.
Fan Installation
Roof Mounted Fans
Roof mounted fans should normally be attached to equipment support curbs to keep them above the roof line by at least 12”. To
install the roof curb, the fan must be disassembled to be able to attach the fan to the curb. See Fig. 2 for details.
