Set Up
Unpack system and make sure all components are accounted for according
to the diagram below according to your specific series number. If any com-
ponents are missing or damaged contact your Watts representative. If they
can not be reached contact Watts customer service at 800-659-8400.
* Drain line flow controller for LCTA-100 Series is factory installed in valve’s drain port. Drain line flow controller for LCTA-150 may come loose or assembled on control valve’s drain
port depending on system size. Verify drain line flow controller is present before proceeding. See installation Diagrams page 12-13 Drain and Brine Connection Detail for assistance.
Distributor tubes ship inside mineral tanks.
** Water softening systems that use mineral tanks larger than 12" in diameter are not factory loaded with resin and gravel. For unloaded systems, the media is in bags and ship on
the system pallet. The proper amount of media is supplied for the mineral tank used.
