Replacing the Filter Cartridge
6.
Reset the LCD gallon count from 0 to 1500 gallons by following
steps in
‘battery replacement’
section on next page, step 3.
7.
Place the system on flat surface and turn on the water supply. Let
the water run for several minutes to flush out normal carbon fines.
1.
Turn off water. Unscrew the housing
from
base
by
turning
it
counterclockwise using the supplied
filter wrench.
2.
Remove the old cartridge and discard.
At this point, it is recommended to
clean the housing from inside.
3.
Check the O-ring for wear & tear. O-
ring rests above the thread in the
base.
- If it is worn, replace it.
- If it is in good working condition,
lubricate
it
with
food-grade
petroleum jelly to ensure it lies flat
and prevents leaking.
5.
Pick up the base and screw the housing tight enough with hand
first. Doing it this way will prevent the O-ring from slipping loose
and causing the filter to leak. Once the filter housing is hand tight,
tighten it an additional 1/4 to 1/2 turn with the supplied filter
wrench to prevent any leakage.
4.
Unwrap new filter cartridge from plastic wrap
and place it on the filter base with side marked
up facing up (see picture on the right). Put the
housing back on. Apply some petroleum jelly on
housing threads for easier unscrewing next time.
