MAINTENANCE AND CARE
How to check for cartridge damage
The ultra filtration membranes have been
integrated into a robust cartridge and
have been designed for a long service
life. However, if treated incorrectly, the
cartridge is liable to break.
The membrane integrity check should be
performed every time the bottle has been
subjected to shock or when you suspect
damage may have occurred to the bottle.

CAUTION
Do not subject the bottle to shock
or misuse the bottle by inserting
objects into the cartridge.
Membrane Integrity check
• Unscrew and remove the pump base
from the bottle. Fill with water through
the blue pre-filter sponge to within 1
inch/2.5cm of the brim. Screw the pump
base back into place.
• Hold the bottle in the vertical, upright
position with the screw top facing
upwards for the duration of the
membrane integrity check.
• Open the snap-fit lid and pump 4 - 6
times.
• Open the nozzle with clean hands to
allow the water to flow. Apply another 4
- 6 pumps when water flow slows down
to drain the bottle of all of its water.
• If the bottle spits water from the nozzle
and water does not flow freely then
air is being expelled from the nozzle
along with water.

This means that
the cartridge is damaged. Stop using
the bottle and replace the cartridge
(see page 13 for how to install a new
cartridge).
• If water isn’t spitting from the bottle,
but flow rate is slower than normal
despite the bottle being 1/4 full at
either the horizontal or vertical position,
clean the bottle as dirt and debris may
be causing slower flow rate. If the
bottle has been cleaned and water
flow remains slower than normal, the
cartridge may be reaching the end of
its life (see page 19 for FAILSAFE™
TECHNOLOGY).
