STEP 1

2 Purge all water from the plumbing lines by turning on all faucets in your home and draining completely.

3 Press the red pressure-relief button on top of the Filter System A to release pressure.

4 Use the Filter Housing Wrench D to unscrew the Filter Housing.

NOTE: Use a pan or bucket to catch any water in the Filter Housing.

STEP 2

NOTE: Have a pan or bucket handy to rinse out the Filter Housing.

1 Rinse out the bottom of the Filter Housing.

2 Add enough water to fill the Filter Housing 1/3 full. Add approximately 2 tablespoons of bleach and clean the System Head and

bottom of the Filter Housing with a clean cloth.

3 Rinse the Filter Housing thoroughly to remove bleach.

4 Remove the O-Ring B in the top of the Filter Housing and wipe clean.

5 Use silicone grease to lubricate the O-Ring.

6 Place the O-Ring back in the groove of the Filter Housing.

NOTE: Make sure that the O-Ring is seated properly in the groove to ensure a good seal.

STEP 3

1 Insert the new Filter Cartridge over the standpipe in the bottom of the Filter Housing.

2 Screw the Filter Housing back onto the System Head and hand-tighten. Using the Filter Housing Wrench, tighten 1/4 turn.

NOTE: Do not over tighten.
