Thank you for your question on the model PP650 central vacuum system. The PP650 would be compatible with all of our current as well as past central vacuum installations. If you are replacing an existing NuTone system, you will need to do a little modification on where the tubing from inside the house meets the main canister. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
