Product Setup
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 11, 21, 22)
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. Reattach 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
Impor
tant: 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 PETBottle to the bottom of the Combi filter. Use the extra bottle adaptor included
for compatibility with other bottles (e. g. Sigg, Nalgene)*. (Figure 22)
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.
