When we bought our house last fall, the owners left behind an old Hayward Navigator. However, they left no info, manuals, etc... The unit works fine, but it gets hung up regularly (most commonly on the main drain). I have no info on how this is supposed to work - so I welcome any input anyone might have.
Is this supposed to be programmed for the pool in some way? Is the a particular location where it should begin? Is there something I am doing that is causing it to get stuck on the main drain (I am shutting off that drain while vacuming).
