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 using the sump wrench tool provided.

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.

If you are replacing the batteries, remove, properly discard
and install two new “AA” alkaline batteries in the 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 and allow the fine,
harmless carbon particles to purge from the cartridge. Turn off
the faucet when you no longer see the particles in the filtered water.
