with water and a soft brush. Reassemble. Apply a small amount of silicone lubricant to the
strainer barb to ease assembly. (Figure 22)
For use without the weight. The prefilter is functional with or without the weight (we
recommend using with the weight). To use without the weight, remove the strainer barb from
the input hose. Reassemble without the weight.
4) Storage: Your Katadyn water system comes with a carry bag for storage. To prevent
the possibility of cross contamination, remove the output hose and EasyFill Bottle Adaptor
and store separately in a resealable bag inside the carry bag.
LongTerm Storage (After Your Trip Is Over)
Disinfect your microfilter before storage to prevent microbiological growth within the pump.
1) Fill a liter container with tap water and add 2 tablets of Micropur
Forte (if not available use 2 tablespoons of ordinary household bleach).
2) Place prefilter into solution.
3) Pump entire amount of solution through unit (into sink or container).
4) Remove prefilter from the solution and continue pumping another 5 to 10 strokes to
remove remaining water from the pump body and hoses.
5) Remove cartridge and allow to dry.
6) Wrap hoses around body and store in carry bag.
Note: When removing unit from longterm storage, flush the system with one liter of water to
remove any stale tasting water.
Cartridge Capacity
Cartridge capacity depends on water quality. The Katadyn Hiker was tested at 200 gallons and
found effective for removal of bacteria and protozoan cysts like Giardia and Cryptosporidium. For
maximum performance, cartridge should be replaced after 200 gallons (approx. 750 liters) or
when the unit becomes hard to pump.
Cartridge Installation
Replacement cartridges are available from the dealer where you purchased your Katadyn Hiker.
1) Remove output hose from cartridge output barb. Grasp the top of the cartridge and
unscrew counterclockwise. If on trail, pack out used cartridge and discard in trash
receptacle.
2) Rinse inside of Hiker housing by swishing with clear water (nonfiltered water is ok).
Discard water. Wipe inside of housing and housing threads with soft cloth to remove
sediment.
3) Remove new cartridge from packaging.
4) Insert new cartridge into housing and tighten clockwise.
5) Reattach output hose to cartridge output barb. (Figure 11)
6) Flush cartridge by pumping and discarding the first liter.
