Using RainSoft Centurion with other water treatment equipment
Due to the unique properties of RainSoft Centurion, there are some
unique requirements for using RainSoft Centurion in conjunction with
filtration or other forms of water treatment.
1. RainSoft Centurion must be the last stage in the treatment chain. Do
not install any filters after RainSoft Centurion or before any devices for
which scale prevention is required. POU filters, e.g. carbon or RO are
exempt from this requirement.
2. Do not apply phosphate or any other antiscalant either before or after
RainSoft Centurion.

Installation Instructions
Notes to the Installer:
The RainSoft Centurion system differs from a conventional softener or
media filter in a number of key respects.
• The system is light and only partially filled with media. This is normal.
The UP-flow operation of the system requires a lot of freeboard to
allow the bed to fully fluidize.
• Because the RainSoft Centurion system operates in the UP-Flow mode,
the tank connections are opposite of what you’re used to.
