To change the filter mode, detach pump head by turning and lifting the pumphead from
the filter housing. Next, hold the housing in one hand and turn the ceramic prefilter
unit until the white arrow points to the desired mode. (Picture D) Reattach pump head
and close tight.
Note: The ceramic prefilter can easily be cleaned by brushing with the supplied
cleaning pad.
2) Connect Hoses
Remove the red plastic cap from the input barb; retain for storage. Connect input hose
(with prefilter) to input barb in the middle of the pump head. To use with Nalgene
bottle, remove bottom cap and screw Vario to top of bottle. To use with hydration
bladder, remove bite valve from hydration bladder and connect bladder drink tube to
the outlet port of the bottom cap. To use with output hose, remove the bottom cap and
attach one end of the output hose to the output barb. Push the enclosed bottle clip on
the other end of the output hose. (Figure 1-1, Pictures A, B, C)
3) Flush System
Important: Before first use, flush system by pumping approximately 1 liter of water
through the unit to remove harmless carbon dust. Slightly discolored water is normal
when flushing. See following section on Normal Operation on how to filter water.
Normal Operation
1)
Place input hose in untreated water source. Adjust the float to keep prefilter off the
bottom and away from sediment.
2)
Remove the bottom cap and retain. Connect a Nalgene Bottle to the bottom of the Vario
filter (Picture A) or attach the output hose to the output barb. (Picture B) Alternatively
connect hose of hydration bladder as described above.* (Picture C)
3)
Make sure the hoses are not kinked. Pump the handle in a slow, steady manner.
4)
After filling water container with filtered water, unscrew bottle/remove outlet
hose/remove bladder drink tube and remove prefilter from water source. Continue
pumping to remove remaining water from pump body. If applicable, screw bottom cap
back on housing. To protect the inside from dirt, turn outlet port until covered.
5)
Store unit in the carry bag. To prevent the possibility of cross contamination, store the
output hose with the clip separately in the resealable bag inside the carry bag.
*Note: Before each use, flush and discard a small amount (5 – 10 strokes) of water to
remove stale taste.
Field Performance Tips
To extend cartridge life, always use the best water source available.
Keep
the intake prefilter clean and off the bottom. In heavy sediment conditions, wrap a coffee
filter or bandanna around the intake 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.
