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
conditions, wrap a coffee filter or bandanna around the input prefilter. Where possible, place
untreated 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
ceramic 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 carbon 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.
