Filter Cartridge Replacement
CAUTION:
Never remove the sumps when water pressure is in the Water Filtration system.
Close the water supply/saddle valve to the filter.
(See Fig. 1 in the
Installation Overview
section
for location of the saddle valve.) Press the vent valve on the top of the
Filter
I head to relieve
the pressure in the system, or open the filtered water faucet.
Remove the sump, using the sump wrench tool provided, from the filter head by rotating the
sump as shown in the below illustration. Be careful, the sump may be full of water. Be sure to
keep the large o-ring seal.
If you are replacing a filter cartridge, remove and discard the used filter cartridge.
Be sure the inside of the sump is clean. Thoroughly wash the inside of the sump with hot,
soapy water and rinse.
Remove the wrapper from the new filter cartridge and insert the filter cartridge in the sump.
Some cartridges fit either way, while others fit only one way. Observe markings on the
cartridge.
NOTE:
The Water Filtration system uses two different types of filter cartridges. Be sure to
install them correctly.
The sediment/taste and odor filter
(FXUS)
should always be placed in the
Filter
I
sump.
Lightly lubricate the o-ring seal in the sump with clean silicone grease. Be sure it is fully
seated in its groove.
Hold the sump up to the filter head, aligning the center hole in the cartridge with the
protrusion on the bottom of the head.
Being careful not to cross-thread, rotate the sump onto the filter head and tighten securely
by hand.
NOTE:
If the sump will not tighten up to the head, you may have the cartridge in upside
down. Take the cartridge out and check for correct orientation.
Repeat steps 2 through 8 for Filter
II.
Turn on the filtered water faucet. Then, slowly open the water supply/saddle valve and allow
the filter housing to fill. While it is filling, press the filter vent valve to release air in the filter.
Close the filtered water faucet. Then, check for leaks between the sump and the head.
NOTE:
If leaking, turn off the water supply and turn on the filtered
water faucet, or press the
vent valve to depressurize the filter. Disassemble the filter and check the o-ring for cuts, flat
spots, etc., and sealing surfaces for foreign material. Clean the o-ring and lightly lubricate
with clean silicone grease. Carefully press into the groove in the sump.
The filter cartridges contain activated carbon, a black powder. When new, turn on the
filtered water faucet for ten minutes to allow the fine, harmless carbon particles to purge
from the cartridge.
