Clean the camera lens in the same way. If any
permanent spots or debris appear under the
camera's glass lens, it cannot be wiped clean
and will require replacing the camera itself.

7.2.3 Cleaning the Exhaust System

To check and clean the exhaust system at least once a week:
• Check the external fan and surrounding ducts for excessive accumulation of dust and debris.
For best results, use a brush, vacuum, or compressed air to remove large accumulations of dust
and debris, and use mild cleansers and soft rags or paper towels to fully clean the fan and its
blades at least once a month.
•
While you are doing the weekly inspection, check the seams and joints of the ducts for any
damage or leaks.
If any are found, immediately repair them. Caulk or special-purpose aluminum foil tape generally
works best if available; standard duct tape can deteriorate over time, especially near heated
components.
