I'm not an engineer, but number 7 means the device is protected by thermal 
fuse in case it overheats. There are many different kind of thermal fuses. 
Some can be reset, some have to be replaced.

This could be a nice DIY project too. You can buy 156 Watt Peltiers 
(thermoelectric chips) for less then $30. Get some heatsink, fan, plastic 
hose and put it in-line with your canister filter.

If anybody wants to know more about Peltiers and how to use them, search 
here http://www.google.com for 'cpu cooling peltier' ( since Peltier is 
also very good for cooling your overclocked CPU :-]]   )

I hope this was not too far off topic.
