rate and/or quality of product water drops. Product water
may begin to taste different or bad, indicating solids and
organics are passing through the RO membrane. When
replacing the RO cartridge, replace the prefilter and post-
filter cartridges as well.
To replace the RO cartridge (see Figure 6):
1.
Remove (turn to the left) the pre filter cartridge from
the filter head to relieve pressure on the Reverse
Osmosis cartridge.
2.
Remove the RO cartridge.
3.
Remove the post filter cartridge.
4.
Discard the cartridges in a proper manner.
5.
Install new cartridges in reverse order (post filter,
Reverse Osmosis and then prefilter). Turn cartridges to
the right to re-attach to the filter heads.
6.
Purge the RO membrane cartridge following instruc-
tions on page 10.
FLOW CONTROL
The flow control is vital for proper operation of the RO
membrane cartridge. The control keeps water flow
through the membrane at the needed rate to obtain the
best quality product water.
Periodically check the flow control to be sure the small
hole through it is clean and unrestricted.
