product should never be placed near or over a radiator or heat register. This product
should not be placed in any area where proper ventilation is not provided.

your dealer or local power company.
8. Do not allow anything to rest on the power cord. Do not install this product where
the cord may have anyone walking on it.

operation.

damaged.
