I just received my Kreepy krauly/Pentair/Letro Legend II automatic pressure side cleaner (it is like the polaris 360 - no booster required) and "comes equipped to connect to a 1.5" threaded (female) dedicated return line". The only problem is my dedicated return is much smaller (either 3/4 or 1"). Does anyone have any experience as to how to connect? Sadly technical support doesn't seem to know...
