<p>BSS Audio incorporates high quality mechanical fans
in some products. All mechanical fans have a limited life
expectancy. We recommend annual inspection of fans for
dust occlusion and excessive noise. Fan assemblies should
be replaced after six to ten years of use. Environmental
factors such as elevated temperature, dust, and smoke
can adversely affect fan life. Systems exposed to these
conditions should be inspected more frequently. Fan replacement
can be performed either at the factory or by an experienced
technician in the field. Please contact BSS Technical
Support for more information on purchasing replacement
parts or product service. BSS Audio has a policy of continued
product improvement and accordingly reserves the right
to change features and specifications without prior notice.</p>
