Filter Cartridges
FILTER CARTRIDGE LIFE
It is recommended to replace filter cartridge every
six months of use. There are several variables that
determine how long a cartridge will last.
These include:
1. How much water you use, and
2. How much sediment, taste and/or odor, or other
unwanted substance, is in the water.
You will know it is time to replace the cartridge when
you first notice the return of the unwanted sediment,
taste and/or odor in your water, or when the flow
diminishes or stops.

FILTER CARTRIDGE REPLACEMENT
NOTE: It is not necessary to shut off the water supply
when replacing the filter cartridge.
1. Grasp the lower part of the sump and pull it firmly
and slowly toward you, pivoting upward until it stops
in the bypass/filter change position (See Fig. 10).
You may notice a hissing sound, as a small amount
of water (approximately 4 ounces) is expelled into the
vent tube to relieve pressure in the sump.
2. Pull the sump downward out of the head.
NOTE: To avoid unintended water flow from the filter
head, do not pivot filter head down to the serv-
ice position without the sump and replacement
filter cartridge in place, as shown in Figure 16.
3. It is recommended to take the sump assembly to a
sink or level waterproof surface before opening it.
4. Unsnap the lid clamp by pulling its latches in oppo-
site directions, as shown in Fig. 11. Do not pry or
use tools, as this may damage the assembly.
