Component Inspection and
Maintenance
Visually inspect the major components on the control pod and fans for dirt and
damage. Dirt build-up on some components can lead to component damage or
failure. Avoid damage to the product by replacing components and/or circuit
boards with burn marks, breakage, or foil delamination. Follow the
Recommended Preventative Maintenance on page 25
and these inspection and
maintenance instructions.
