Product Set-up
The Combi requires minimal set up. For best results, try out the Combi before first field use to
familiarize yourself with its operation.
1)
Prefilter
The modular prefilter (Figure 2-1) is effective in still and running water. It consists of two
components: a strainer and a weight. The prefilter is important because it prevents large
particles (larger than 130 microns) from entering the water system. See Field Performance
Tips for helpful hints.
2)
Connect Hoses
Push the hose float on to the input hose (hose with prefilter). Position the float approx.
4 inches (10 cm) from prefilter. Attach the hose to the input barb in the middle of the filter
housing. (Figures 1-1, 2-1, 2-2)
3)
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
cartridge in case some is spilled.
4)
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
deposited on the surface of the ceramic. The ceramic must be cleaned after the first 0.5 litres
to prevent early plugging of the filter. Repeat this procedure any time carbon is replaced.
See following section on Field Performance Tips on how to clean the ceramic.
Normal Operatio
n
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.
