Hoover UH70015 Owner's Manual page 4

WARNING:
To reduce the risk of electric shock, this appliance has a polarized plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician
to install the proper outlet. Do not change the plug in any way.
THERMAL PROTECTOR: An internal thermal protector has been designed into your cleaner to protect it from overheating.
When the thermal protector activates, the cleaner will stop running. If this happens, proceed as follows:
1. Turn the cleaner OFF and disconnect it from the electrical outlet.
2. Check primary filter, HEPA filter and Umbrella tube for dirt accumulation.
3. Refer to "Troubleshooting" section.
4. When cleaner is unplugged and the motor cools for 30 minutes, the thermal protector automatically resets and cleaning may continue.
If the thermal protector continues to activate after following the above steps, your cleaner may need servicing (see "Service" section).
