The TDS Meter
Option 2. Installing the PSI Meter on the section of white tubing coming out of the third pre-filter
housing (that attaches to the auto shut off valve) will allow you to monitor the psi of the
OUTPUT water of the 3 pre-filters. When you install new pre-filters make a note of the psi
reading at this point. Write down the psi measurement with some permanent marker on a
piece of masking tape and stick it somewhere visible on the system. Now you can check to
see when the psi on this line drops to 15% below the initial reading you wrote down (0.85 x
initial psi reading). When this happens it is time to replace your pre-fllters. You might want
to also write down on the masking tape the number you are watching for, 0.85 x initial psi
reading, to make it easier to determine the status of your system.
14.2 How do I use the TDS Meter from my “COMBO” System?
The TDS (Total Dissolved Solids) Meter of your system is ex-
tremely easy and intuitive to use and comes with its own set of
intructions, but here is a quick tutorial. First you will need to get
a small glass and rinse it of all dust or other particles. Now fill the
rinsed glass with the water for which you would like to deter-
mine the TDS Reading (Total Dissolved Solids). Remove the cap
from the bottom of the TDS Meter and turn on the meter. Now
simply insert the portion of the TDS Meter that was covered by
the cap into the glass of water. The number that shows on the
digital display is the ppm count (Parts Per Million) of TDS (Total
Dissolved Solids) in your water.
Note: Your TDS Meter has an auto shut off feature but try to remember to shut off the TDS Meter when
you are done testing your water to save on batteries !
14.3 How do I store my extra case of 27 (6 changes) pre-filters, post-filters and remineraliza-
tion cartridges?
Your case of 27 pre-filters, post-filters and remineralization cartridges (6 full changes) can be stored in
the same state in which they arrived. Each filter comes wrapped in protective plastic. Store at room
temperature. Shelf life is years.
