NOTE:
Operation of this unit without level switches (i.e. Direct Feed) requires a jumper to
be installed (typically installed at factory) between the float switch connection
terminals TB3-7B and TB3-8B.
NOTE:
Connect the color-coded cable conductors inside the RO Controller to their
associated terminal barrier strip locations.
