BEFORE YOUR FIRST USE,
you will need to flush the Purifier
Cartridge of loose carbon dust and glycerin, which are
harmless but don’t taste very good. Follow
Steps 1.1-1.8
under Purify Water. After purging the air and dirty water
(Step 1.7)
, filter about ½ liter of water to waste before
filtering into your drinking vessel.
Disconnect Inlet Hose from Dirty Water Reservoir.
Fill Dirty Water Reservoir with unfiltered water.
Fold Closure Strap on Dirty Water Reservoir
4+ times to seal. Connect the buckles of Closure Strap
to each other.
Suspend Dirty Water Reservoir by Hang Strap.
(NOTE: Hang Dirty Water Reservoir as high as
possible without pulling the clean container off
the ground.)
Ensure Shutoff Clamp and Purge Valve are
both closed.
Reconnect Inlet Hose to Dirty Water Reservoir.
Open Purge Valve to start water flow, flushing any dirt
and air until the water is the same color as the source
water and free of bubbles. (NOTE: Holding the car-
tridge horizontally and gently tapping it helps release
the air.)
Close Purge Valve.
Remove Clean Side Cover and open Shutoff Clamp,
allowing water to flow. Rinse Bottle Adapter with
filtered water. (NOTE: If this is your FIRST use of the
cartridge, filter about ½ liter of water and discard it.)
Attach a clean container to Universal Bottle Adapter,
ensure Outlet Hose isn’t kinked, and allow water to fill
vessel. (NOTE: Trapped air in the cartridge will affect
flow.)

1. PURIFY WATER
The Purge Valve releases concentrated dirty water. DO NOT allow any drops
to splash into your clean water. Cross-contamination can expose you to microorganisms and increases
your risk of gastrointestinal illness.
