How Your System Works
For best results it is recommended to install the R/O
on a COLD softened water supply. The RO systems
use four stages of treatment to filter your water:
Stage 1
- Remove sand, dirt, sediment
Stage 2
- Remove chlorine, taste & odors, very fine
particulates
Stage 3
- Reduce total dissolved minerals
Stage 4
- Polish water for refined taste
If water pressure drops below 5 psi, the system will
shut down. When the pressurized storage tank
reaches 36 psi, the system (at the end of each tank
full cycle) will automatically perform a 20 second fast
flush to clean the membrane and prolong its the life
expectancy. When the tank pressure reaches 22 psi,
the system will start producing water again.
Recommended Filter Change Schedule
Your filters require changing on a regular basis. In-
structions to change them are on page 8. The sched-
ule below is the minimum recommendation. Depend-
ing on your water conditions the filters may need to
be changed more often.
Filter Cartridges Change Schedule
Pre-‐filter (Sediment) Every 12 months
Pre-‐filter (Activated Carbon) Every 12 months
Post Filter (Activated Carbon) Every 12 months
R/O membrane Every 24-‐36 months
