Converting from Ceiling to Cabinet Design for Ceiling Exhaust Fans

General Maintenance Suggestions
Ceiling exhaust fans require very little maintenance, but since small problems over time left unchecked could lead to
loss of performance or early motor failure, we do recommend that the unit be inspected periodically (once or twice a
year).
The fan motor and wheel should be checked for dust and dirt accumulations. Dirt buildup can lead to loss of
performance and motor overheating. Cleaning can be accomplished by brushing off any dust that may have
accumulated. Even filtered units can accumulate build-up and should be checked when cleaning filters.
The motor should be checked for lubrication at this time. Lubricate only those motors which have an oil hole
provided. A few drops of all purpose oil (SAE 20) will be sufficient.
