Hi guys need help camin a jandy actuator to do 90 degrees instead of 180. It's installed in a 3 side valve and would like it to go from right to center. So that there is splash over. The left side is for the return jets and the right side is for the waterfall (no spa) of I go full 180 it will open the waterfall full but won't have return jets for circulation. Any help will be appreciated. I opened the unit and tried the top and bottom cam but can't seem to set it correctly. It can't go over cause it would close the main return inlet from the filter.
