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. "ALTERING
OR TAMPERING WITH THE FAN WILL VOID THE WARRANTY".
