About the water filtration system.
Filter Cartridge Installation or Replacement
Never remove the sumps when water pressure is in the water filtration system.
CAUTION:
Close the water supply/saddle valve to the filter. (See the Installation Instructions for saddle valve location.)
1
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
2
in the below illustration. Be careful, the sump may be full of water. Be sure to keep the large o-ring seal.
Turn sump wrench tool
provided clockwise
If you are replacing a filter cartridge, remove and discard the used filter cartridge.
3
Be sure the inside of the sump is clean. Thoroughly wash the inside of the sump with hot, soapy water and
4
rinse.
Remove the wrapper from the new filter cartridge and insert the filter cartridge in the sump. Some
5
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.
6
Hold the sump up to the filter head, aligning the center hole in the cartridge with the protrusion on the
7
bottom of the head.
Being careful not to cross-thread, rotate the sump onto the filter head and tighten securely by hand.
8
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 .
9
Turn on the filtered water faucet. Then, slowly open the water supply/saddle valve and allow the filter
10
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.
11
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.
If you are replacing the batteries, remove, properly discard and install two new "AA" alkaline batteries in the
12
battery pack. Removing the batteries or momentarily disconnecting the leadwires resets the six month
electronic timer.
The filter cartridges contain activated carbon, a black powder. When new, turn on the filtered water faucet
13
for ten minutes to allow the fine, harmless carbon particles to purge from the cartridge.
