Introduction
Thank you for purchasing simple SDI. We hope you’ll find simple SDI to be an indespen-
sible tool.
We designed simple SDI with feedback from experts familiar with other automated SDI
measurement systems as well as those who’d performed more manual tests than they care
to remember. We incorporated as many of their suggestions as we could. For example:
• simple SDI is battery powered for true portability.
• simple SDI uses standard .45 micron, 47 mm membranes, no encapsulated or propri-
etary size single-source membranes.
• simple SDI operates on as little as 35 psi feed water pressure. Testing is now possible
on many water supplies that previously required a booster pump.
• simple SDI is housed in a rugged crush-proof case. No flimsy tissue-thin plastic here.
As good as simple SDI is, there’s always room for improvement. If you have an experi-
ence, idea or input either positive or negative we’d love to hear from you.
Again, thanks for your purchase. Welcome to the community of simple SDI users.

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.

NOTE! simpleSDI is a precision instrument and should be used accordingly. Do not drop
or otherwise physically shock the meter. Do not submerge or spray with water. Do not
leave in direct sunlight or other unprotected environment.

Setting up simple SDI: Prelter installation and Supply Water Connection
Feed water connection for all other water supplies.
Feed water connection for preltered water supplies.
The illustrations below show how to connect the prefilters. Please note the direction of the flow arrows on
the filters and connect them in the proper orientation. Use the blue 1/4” OD Polyethylene tubing supplied.
There are two short pieces for interconnecting the filters and connecting to simple SDI. There’s one long
piece for connecting to the water supply.
Note: These instructions assume familiarity with the Quick-Connect type fittings that we use. If you
haven’t used these fittings before, please see the appendix for a tutorial on how to use them.

Setting up simple SDI: Filter Holder and Drain Line Connection
Connections Complete
simple SDI is now connected and ready for start-up.
The drain should be able to handle 2 liters/minute for a short duration during flushing and 1 liter/
minute or less for the duation of the test. If a bucket is used it should have about 5 gallons capacity.
To Drain
Slip the drain tubing
over the barb on
the membrane filter
housing.
Insert the tubing on the membrane filter housing
into the fitting on the side of the meter. Press
firmly to securely engage the tubing..

Setting up simple SDI: Start-up & Test Procedure
The Start-Up and Test procedure is really 4 simple steps.
1. Flush the air out.
2. Install the membrane filter.
3. Adjust the pressure.
4. Start the test.
However, simple things are often harder to explain than they are to do. Bear with us. We’ll have you up and
running in no time.
Allow the water to run for 15 seconds or so or
until you see a clear bubble-free stream of water
flowing through the clear blue tubing. Close the
Inlet Valve.
Close the Inlet Valve on simple SDI.
Open the valve at the water source.
Slowly open the Inlet Valve on simple SDI by
turning the handle counterclockwise. Water will
flow through simple SDI.
Tapping on the pressure regulator and/or turning
the knob helps to dislodge air bubbles.
No bubbles

Setting up simple SDI: Test Procedure
The next step is to install the membrane filter. As simple as this sounds there are at least two distinct ways
and perhaps a number of hybrid methods for doing this. We’re going to explain two methods. You chose
the method that works best for you.
Open the membrane filter housing. Using the
tweezers provided, place a membrane on the face
of the filter housing. (Note that the membranes
are white and are separated by light blue pieces of
paper. Make sure that you have a membrane and
only a membrane.)
Put the top back on the membrane filter housing
but do not fully tighten it. Leave it loose enough
so that water can freely escape, about 1/2 turn
less than fully tight.
Open the inlet valve-just enough for water to flow.
Allow water to dribble out of the housing.
When you see clear bubble-free water in the clear
blue tubing, tighten the housing and close the
Inlet Valve. With the inlet valve closed, tighten
the housing further if necessary. (Go to Page 10.)

Setting up simple SDI: Test Procedure
Once the membrane has been wetted thoroughly,
put the top back on the membrane filter housing
and tighten fully. (Go to Page 10.)
Filter installation:Technique #2
Open the membrane filter housing. Hold the inlet
half of the filter housing in one hand. Tilt the
filter housing UP so that the face of the housing
is up and parallel to the ground. Open the inlet
valve very slightly so that water spills out of the
housing. Close the valve while keeping the filter
housing face up and parallel to the ground.
Using the tweezers provided, place a membrane
on the face of the filter housing. (Note that the
membranes are white and are separated by light
blue pieces of paper. Make sure that you have a
membrane and only a membrane.) The “shiny”
side of the membrane should be placed “UP”.
Next, wet the membrane thoroughly. An eye-
dropper or small bottle with a spout are helpful
in doing this.
