6.3 Servicing the Cell
The cell may require removal for periodic visual inspections, or for servicing when debris or
calcium mineral deposits develop. The need to inspect and service the cell is indicated by the
CHECK SYSTEM light flashing and / or a screen message, “Error purify off”; “Check flow” or
“Warning!”; “Check/clean cell”.
6.3.a Removal
Figure 7
The cell is installed with unions on each end to allow
quick and easy installation and removal.
1. Turn off pump and shut off all power.
2. Unscrew the unions at both ends of the cell. (A strap
wrench may be required.)
3. Slide the cell out of the Manifold Assembly.
4. Inspect the cell -
If cleaning is necessary, detach
cell cord from cell.

is designed to automatically self-clean calcium scale
build up that may form on the blades during normal operation.
However, unbalanced water chemistry can cause a heavy scale build
up exceeding self-cleaning capabilities... thus; periodic manual
cleaning may be necessary. The simplest way to avoid this extra work
is to maintain the water chemistry at the levels recommended.
1. The cell titanium blades, seen inside the cell body, should be straight and
clear of any debris on the ends or between the blades.
2. White flaky or crusty calcium build up on the edge or between the blades
will shorten the life of the cell. If required, clean the cell immediately and
determine the cause of scaling.
