And if you have any doubts, contact the vac system's manufacturer (should be a name plate on it somewhere). They could tell you what their preference would be (exterior venting or not) for optimum operating conditions.
Thanks so much for the reply, BridgeMan, I appreciate it. I know, doesn't make sense that you would have to vent it to me either, but when I went to have some work done on the vacuum at an authorized dealer, they did recommend having it vented. According to them, small particles escape going into the cannister and that's why it should be vented. My sister also has a central vac and she said hers is vented to the outside.
Good idea, I think I will just contact Electrolux and see what they say.
