Cartridge Replacement
The frequency with which you will need to replace cartridg-
es is dependent on your feedwater’s characteristics, your
purity requirements and your usage. Replace the cartridges
when the product water purity drops below acceptable lev-
els of resistivity or when organic levels become too high.

Refer servicing to qualified personnel.
Do not disassemble water lines or remove car-

ment that requires electrical service. Disassem-
bly of water lines and removal of cartridges will
result in water spillage. Electrical shock hazard
could result.
NOTE
The cartridges will still contain water when re-
moved. Therefore, you will want to have a sink,
bucket or other waterproof container available
to place them in after removal.

access door.
NOTE
If the EASYpure LF is wall mounted, remove
the power cord and rotate the EASYpure LF
until the cartridge access door faces forward
and the EASYpure LF locks into place.
NOTE
A small amount of water will drain from the car-
tridge when it is disconnected from the lower
socket. Plug the cartridge’s lower opening with
your finger to minimize water spillage while you
finish removing the cartridge.
