CAUTION:
Never remove sumps with water pressure in the Water Filtration system.
Close the water supply/saddle valve (Fig. 1 and 2A) to the filter.
Open the filtered water faucet.
Turn the sump off of the filter head as shown (use the sump wrench provided). Be careful, the sump
is full of water. Locate and save the large o-ring seal. Remove and discard the used filter cartridge.
Be sure the inside of the sump is clean. Thoroughly wash with hot, soapy water and rinse.
Remove the wrapper and labels 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 end of the cartridge.
The sediment
(FXUSB)
filter cartridge 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.
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 the markings on the end of the cartridge for correct orientation.
Being careful not to cross-thread, turn the sump onto the filter head and hand tighten securely (see Fig. 5).
Repeat steps 2 through 7 for the taste/odor (FXUTB) or lead/cyst (FXULB) filter cartridge in the Filter ΙΙ sump.
Open the filtered water faucet. Then, slowly open the water supply/saddle valve and allow the filter
housing to fill.
Close the filtered water faucet. Then, check for leaks between the sump and the head.
NOTE:
If leaking, turn off the water supply and open the filtered water faucet. Then,
disassemble the filter
and check the o-ring for cuts, flat spots, etc., and sealing surfaces for foreign material. Clean the o-ring and
lubricate with clean silicone grease. Carefully press into the groove in the sump.
Remove and install two new “AA” alkaline batteries in the battery pack. Removing the batteries or
momentarily disconnecting the leadwires resets the six month electronic base timer.
The filter cartridges contain activated carbon. When new, open the filtered water faucet for ten minutes
to flush the system.
