Setting up simple SDI: Getting Started
Remove the vinyl plug from the water Inlet fitting
and place it in the Power In jack.
Remove the vinyl cap from the outlet fitting on
the right side of the meter.
Note: Replace the vinyl caps after testing to protect the internal components from foreign
particles and to retain the collets on the fittings.
The minimum prefiltration requirement is the 50
micron prefilter. This filter should be used on every
test. The filter is too large to affect the SDI results
but small enough to protect the internal compo-
nents of simple SDI from damage.
For many water supplies, the optional 5 micron
prefilter is also required. Use the 5 micron filter
on unfiltered water supplies or on water supplies
where the SDI results are high (e.g. SDI-15 greater
than 5) or whenever you receive an “OVER-
RANGE” error message indicating that the plug-
ging factor is 90% or greater.
