4.6 Fan Maintenance & Care
Clean the fan air inlet louvres and squirrel cage impeller regularly. The fan should be kept clean and
dust free. Life of the fan will be shortened if operated in a dust filled environment, or if the fan is
overheated by restricting air supply. Stalling the rotor, or over firing the insert with the fan turned off
will also damage the fan. The fan must not be overheated. Do not disassemble the fan.
