Risk of electric shock or energy hazard. Parts inside this UPS are energized by the flywheel even when the AC power is disconnected. |

The accumulation of dust on the surface of the flywheel can reduce the transfer of heat. The routine replacement of air filters should minimize buildup of dust on these surfaces. Refer to Maintenance Section, "Air Filter - Replace".
If the fins show heavy deposits of dust, the system should be de-energized. The deposits should be wiped off with a clean damp rag.
When you change the air filter, check for the accumulation of dust.
