WARNING
BIOLOGICAL HAZARD
There are hazards associated with backcountry travel and the use of water
filters. Drinking untreated water can result in exposure to harmful microorgan
-
isms and an increased risk of gastrointestinal illness. Using this filter improperly
increases your risk of exposure to harmful microorganisms and increases your
risk of gastrointestinal illness. Reduce your chances of becoming sick by
following the warnings and instructions in this manual and educating yourself
on backcountry water safety
.
YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY AND THE SAFETY OF
THOSE IN YOUR GROUP . PLEASE USE GOOD JUDGMENT
.
Never use the MiniWorks EX to filter seawater or chemically contaminated
water, such as water from mining tailing ponds or near large agricultural
operations. The MiniWorks EX does not make drinkable water from these
sources and does not remove all viruses, chemicals and radioactive materials,
or particles smaller than 0.2 microns.
Keep the Inlet Hose and other potentially contaminated parts away from filtered
water to prevent cross contamination.
READ, UNDERSTAND, AND FOLLOW ALL
instructions and warnings in this
manual before using this filter. Failure to follow war
nings and instructions may
result in gastrointestinal illness.

TIPS
IMPORTANT
Read and understand this entire manual carefully before assembling or using this
water filter. Keep this manual for future reference. If you do not understand
this manual or have any questions, please call Cascade Designs at
1-800-531-9531.
Ceramic Element
Clean the element whenever flow is noticeably reduced to maintain 1L/min. output.
Avoid excessive or uneven rubbing during cleaning because it may cause sur
face
grooves. Measure the element for wear after each cleaning.
CAUTION: Handle the element carefully to avoid damage or breakage.
On extended trips, bring along a spare element.
Water Collection and Preparation
Use the cleanest, clearest water available.
Avoid filtering silty
, cloudy, muddy
, or glacial stream water or tea-colored water that
contains visible tannins because these sources will quickly clog the filter.
If clear water is not available, then let particles settle before filtering. If possible, fill a
container with water and let it stand until particles have settled to the bottom.
Filter mid-container water and discard bottom sediments. Alternately
, collect and strain
water through a bandana or coffee filter to remove particles.
To treat water with suspected waterbor
ne viruses, use an approved disinfectant/purifier
and follow the manufacturer’s recommendations for use. T
o see MSR’s purification
options visit www.msrgear
.com. Further infor
mation on disinfectant use can be found
on the Centers for Disease Control website:
www.cdc.gov
.
Operation
To maximize pumping per
formance, air must exist in the Housing and should be visible
through the clear gray shell when not pumping.
The Clean Side Cover can be threaded onto a Nalgene bottle cap to keep it and the
cap clean when filtering water.
In swift water, place a small rock on the Inlet Cage to keep it submerged below the
water surface.
Please refer to Filter Cleaning and Maintenance section for more information.
