FILTER CHANGE PROCEDURE
NOTE: This system is equipped with an internal shut-off valve.
1. Turn cartridge slowly to the left, about 1/4 turn, until it
stops (when arrows line up). At this position, both inlet
and outlet ports are closed and water pressure has been
relieved.
2. Pull used cartridge straight down and discard. Note:
There may be a small amount of residual water drainage
after pressure is relieved and during cartridge removal.
3. Moisten O-ring with a food grade lubricant and push
new cartridge into filter head. Turn cartridge 1/4 turn
to the right until it stops (when arrows line up). Top
surface of cartridge will become flush with bottom of
the head when fully engaged.
4. Open downstream valve (if installed) and flush new filter
cartridge for two minutes, expelling any trapped air and
carbon fines. Water may run cloudy with air but will
quickly clear.
