1
	for location of the saddle valve.) Open the filtered water faucet.

3 If you are replacing a filter cartridge, remove and discard the used filter cartridge.
4	Be sure the inside of the sump is clean. Thoroughly wash the inside of the sump with hot,
	soapy water and rinse.
5	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 (FXUSB) filter cartridge should always be placed in the Filter I sump.

6 Lightly lubricate the o-ring seal in the sump with clean silicone grease. Be sure it is fully seated in its groove.

7 Hold the sump up to the filter head, aligning the center hole in the cartridge with the protrusion on the bottom of the head.

8 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.

9 Repeat steps 2 through 8 for the taste/odor (FXUTB) filter cartridge in the Filter II sump.

10 Turn on the filtered water faucet. Then, slowly open the water supply/saddle valve and allow the filter housing to fill.

11 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. 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.

12 The filter cartridges contain activated carbon. When new, turn on the filtered water faucet for ten minutes to flush the system.
