Product Setup
The Combi requires minimal set up. For best results, try out the Combi before first field use to famil
iarize yourself with its operation.
1) Connect Hoses
Push the hose float on to the input hose (hose with prefilter). Position the float approx. 4 inch
es (10 cm) from prefilter. Attach the hose to the input barb in the middle of the filter hous
ing. (Figures 11, 21, 22)
2) Filling Carbon Cartige
The Combi may be used with or without the carbon cartridge filled. Use the Combi with filled
activated carbon cartridge whenever the water is chemically contaminated or tastes bad.
Detach the upper part of the filter housing by turning counter clockwise. Remove the pump
handle. Remove the grey activated carbon cartridge from the lower part of the filter housing
and remove the lid. Open package of activated carbon and pour into the cartridge. Close
the lid and insert the carbon cartridge firmly into the housing. Reattach the pump handle to
the housing and tighten by turning clockwise.
Note: There is more activated carbon in the package than is required to fill the carbon car
tridge in case some is spilled.
3) Flush System
Important: Before first use, flush system by pumping approximately 0.5 litres of water
through the unit to remove harmless ceramic dust and carbon dust (if carbon cartridge is
filled) See following section on Normal Operation on how to filter water.
Note: If using the Combi with carbon cartridge filled, harmless carbon dust may be deposit
ed on the surface of the ceramic. The ceramic must be cleaned after the first 0.5 litres to pre
vent early plugging of the filter. Repeat this procedure any time carbon is replaced. See fol
lowing section on Field Performance Tips on how to clean the ceramic.
Normal Operation
1) Place input hose in untreated water source. Adjust the float to keep prefilter off the bottom
and away from sediment.
2) Connect a PETBottle to the bottom of the Combi filter. Use the extra bottle adaptor included
for compatibility with other bottles (e. g. Sigg, Nalgene)*. (Figure 22)
3) Hold the filter vertically and begin pumping the handle in a slow, steady manner. Make sure
the input hose is not kinked.
4) Unscrew water container after filling with filtered water and remove input hose from water
source. Continue pumping to remove remaining water from pump body.
5) Store unit in the carry bag. To prevent the possibility of cross contamination, the input hose
should not contact the output barb.
*Note: Before each use, pump and discard a small amount (0.2 litres) of water to remove stale
taste.

Field Performance Tips
The Katadyn Combi is designed to remove bacteria and protozoan cysts such
as Legionella, Giardia and Cryptosporidium. To extend ceramic life, always use the best
water source available. Keep the input prefilter clean and off the bottom. In heavy sediment con
ditions, wrap a coffee filter or bandanna around the input prefilter. Where possible, place untreat
ed water in container and wait for sediment to settle out until water appears clear  then filter from
water above the sediment.
Maintain your Katadyn water system to keep it operating smoothly.
1) If handle is hard to push
Clogged filter pores. If the filter pores of the ceramic are clogged, the ceramic needs to
be cleaned. Never use force when pumping. Remove ceramic element by turning the
filter base at lower end of housing counter clockwise one quarter turn (the bottom end of the
bottle adaptor may be used to aid turning). Clean the ceramic element by brushing it with
the supplied cleaning pad until the light, originally colour appears again. Insert the ceram
ic element into the housing. Push and turn the filter base clockwise one quarter turn.
Attention: The filter housing can be under pressure  unfiltered water can splash out while
taking out the ceramic element.
2) Lubricate pump handle oring. Silicone lubricant is provided with your new unit.
Unscrew the upper part of the filter housing counter clockwise and remove the whole
pump handle. (Figure 11) Clean excess buildup from black rubber oring on bottom of
handle. Place a small amount of silicone lubricant all the way around the oring. Re
assemble.
3) If unit pumps easily, but no water flow:
Make sure prefilter is submerged.
Make sure that input hose is not blocked or pinched.
Hold the filter vertically until water flows.
The membrane on the lid of the carbon cartridge could be clogged. Remove or clean car
bon cartridge (see below) to restore flow.
4) Carbon Cartidge: Remove dirt particles on the lid of the cartridge by swirling it around
in water or by rinsing. For a more thorough cleaning, gently brush with an old toothbrush
or the green cleaning pad provided.
Attention: Don’t use pressure, otherwise the membrane could tear.
5) Prefilter: Rinse the prefilter in water to remove any particles that may be caught in the
strainer.
6) Storage: Your Katadyn water system comes with a carry bag for storage. To prevent the
possibility of cross contamination the input hose should not contact the output barb.

LongTerm Storage (After Your Trip is Over)
Store the Combi filter as follows:
1) Remove and clean the ceramic element by brushing with the supplied cleaning pad. Allow
to airdry completely.
2) Rinse the filter housing and remove any dirt.
3) Lubricate the orings with silicone lubricant.
4) Reassemble the filter.
5) Store Combi, hose and accessories in the carry bag.
Note: When removing unit from longterm storage, flush the system with one litre of water to
remove any stale tasting water.
Ceramic Capacity
Ceramic capacity depends on water quality. The dirtier the water the more often you will have to
clean the element. This reduces the capacity of approx. 13,000 gallons (50,000 litres). If the gap
of the measuring gauge fits over the ceramic it is time to replace the filter. (Figure 23) Inspect the
ceramic for cracks after cleaning, if you dropped the filter or if you had freezing temperatures. If
the filter shows cracks it will no longer protect you from microorganisms.
Ceramic Installation
Replacement filter elements are available from the dealer where you purchased your Katadyn
Combi.
1) Remove ceramic element by turning the filter base at lower end of housing counter clockwise
one quarter turn (the bottom end of the bottle adaptor may be used to aid turning).
Attention: The filter housing can be under pressure  unfiltered water can splash out while
taking out the ceramic element.
2) Remove new ceramic element from packaging.
3) Insert the new ceramic element into the housing. Push turn clockwise one quarter turn.
4) Flush ceramic element by pumping and discarding the first litre.
Activated Carbon Capacity
Activated Carbon capacity depends on water quality. Normal capacity of carbon is 50 gallons
(200 litres) High chemical or odour concentration can reduce the capacity of the carbon. Replace
the carbon when you notice an unpleasant taste or odour after filtering or after 6 months of con
stant use –whichever comes first. Use the red button on the front side of the housing to keep track
of when the carbon needs to be changed. Use a coin to adjust to the adequate month.

When You Travel Abroad, Camp or Backpack…
…you run a risk of illness ranging from the inconvenience and discomfort of diarrhoea to more
serious illnesses caused by protozoan cysts (i.e., Legionella, Giardia, Cryptosporidium), viruses
and bacteria.
The microorganisms that cause these diseases are often found in the food and water you consume.
Lakes, streams and the local water supply may be contaminated.
To minimize the risk of contracting these illnesses, we suggest that you consult with your physician,
state health department or traveller’s clinic 46 weeks before you depart.
And while you are travelling…
• Make sure that prepared food is thoroughly cooked.
• Select noncooked foods (fruits, nuts, etc.) that have intact shells or skins, and clean your hands
before peeling the food.
• Wash your hands with soap and water thoroughly and often, especially before you eat. Filter all
drinking water with your Katadyn Combi Water Microfilter.
The Katadyn Combi Microfilter is an essential piece of outdoor equipment. For questions or
