Using HELIX™-Valve
1. First time use: Remove shrink-wrap from HELIX™-Valve.
2. Unlock valve from shut-off position by turning mouthpiece
180º counter-clockwise until it locks in OPEN position
(drawings 4, 5).
3. Now you know how to operate the valve, it's time to
drain the first water you have filled in the reservoir.
Go to page 12 to see how it's done and continue
from here:
4. Drinking: To drink, bite lightly on the HELIX™-Valve groove
and sip (drawing 6).
5. To close the valve, turn mouthpiece 180º clockwise until it
locks in CLOSE position (drawing 5).
6. When not in use, cover HELIX™-Valve with the Dirt-Shield™
(available in most of the models) or tuck it in the docking
station (standard in some of the models or purchased as an
accessory).
Notes
To get maximum flow, bite only slightly on the
biting zone. Strong biting will result in blocking
the valve orifice and no liquid will flow.
Tips To avoid the first warm sip in hot weather:
after drinking, bite lightly on the HELIX™-Valve
for a couple of seconds while keeping your lips
apart to let air into the tube. Liquid remaining
in the tube returns to the reservoir.
