1. Turn off water supply to filter.
2. Depress the RED pressure release button to relieve pressure in filter housing.
3. Unscrew blue housing using spanner wrench.
CAUTION: Do not lose O-Ring that is in blue housing. When opening housing to change cartridge, it is common
for the O-Ring to lift out of blue housing or stick to black cap.
4. Remove used cartridge and discard. Rinse out blue housing and fill about 1/3 full with water.
Add about 2 to 3 tablespoons of bleach and scrub thoroughly with a brush or sponge. Rinse thoroughly.
5. Remove O-Ring from blue housing and wipe groove and O-Ring clean. Lubricate O-Ring with a coating of clean
silicone grease. (Do not use Vaseline or other petroleum-based lubricants.) Place O-Ring back in place and press
O-Ring down into the groove with two fingers.
NOTE: This step is important to ensure proper seal. Make sure the O-Ring is seated level in the groove.
CAUTION: If O-Ring appears damaged or crimped it should be replaced at this time. See your local dealer
for replacement parts.
6. Insert the new HEATER GUARD replacement filter cartridge into the blue housing making sure that it slides down
over the housing stand-pipe found at the bottom of the housing.
CAUTION: The standpipe must insert properly into the bottom of the filter before you go to Step # 7
7. Twist the blue housing onto the black cap and hand tighten. DO NOT OVER-TIGHTEN.
CAUTION: Make sure the standpipe found at the base of the black cap seats properly into the top of the filter.
8. Turn on the water supply slowly to allow housing to fill with water.
9. Depress the RED pressure release button to release trapped air from the unit and check the installation for any
leaks.
Replacing the Filter
Filter service life is based on local water conditions and usage and should be replaced as needed, not to exceed one year.
Please Note: The gauge is based on pressure differential. It can only be observed while water is flowing through
HEATER GUARD and will only move when filter cartridge has been prematurely clogged or restricted.
The gauge is only a precaution to prevent problems.
