Aquathin PEARL 30 Getting Started page 39

Q: How long will my CARB 6 post-filter last before it
needs to be replaced?
A: Your Aquathin PEARL system has been designed to
operate within a wide range of tap water conditions.
These conditions vary greatly across municipalities, so it
is difficult to state precisely how long your post-filter will
last. We have designed the system so that under the most
extreme conditions your post-filter will still be
performing correctly after 12 months of use. The CARB
6 post-filter should be replaced when changing the RO
module (once in 2-3 years). This will insure your system
is consistently performing as designed, producing ultra-
pure water that meets the standards for biocompatibility.
Q: How long will my reverse osmosis module last?
A: The module's life depends on the water conditions as
listed in the specification section of this manual. If all
these conditions are met, the life of the module is
generally 2–4 years. If a module fails or its performance
becomes reduced before this time, the cause can usually
be traced to tap water conditions outside the
specifications or failure to flush.
Q: How do I know if there is a problem with the module?
A: The best method is to measure the resistivity
(conductivity) of the RO water and compare it to the tap
water. You can invest in a reliable and inexpensive
resistivity meter available from your Authorized
Aquathin Dealer or you can send them samples for
analysis. (Poor rejection rates may also be an indication
of a clogged pre-filter, so check that filter first.) A large
increase in the production rate is also an indication of
module failure, and can often be traced to the module
having been subjected to either freezing or hot water.
Q: How can I monitor the performance of the unit?
A: Your Authorized Aquathin Dealer will register your
warranty card and purchase with Aquathin Corporation.
