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.
