How to change the BB-Guard-Filter-3/4 filter in your EWS Heater Guard.

The process of changing the BB-Guard-Filter-3/4 filter in your EWS Heater Guard is simple and straightforward.

Please follow these steps carefully:

1. Turn off the water supply to the filter: This is to prevent water from gushing out when you open the filter housing.

2. Relieve pressure in the filter housing: You do this by pressing the RED pressure release button.

3. Unscrew the blue housing: Use a spanner wrench for this. Be cautious not to lose the O-Ring that is in the blue housing. When opening the housing to change the cartridge, the O-Ring often lifts out or sticks to the black cap.

4. Remove the used cartridge and discard: This is self-explanatory. The old cartridge is no longer needed.

5. Rinse out the blue housing and fill it about 1/3 full with water: Also, add about 2 to 3 tablespoons of bleach and scrub thoroughly with a brush or sponge. This step is to ensure the housing is clean for the new cartridge.

6. Clean and lubricate the O-Ring: Remove the O-Ring from the blue housing and wipe the groove and O-Ring clean. Lubricate the O-Ring with clean silicone grease. Avoid using Vaseline or other petroleum-based lubricants. Place the O-Ring back in place, ensuring it's seated level in the groove. Replace the O-Ring if it appears damaged or crimped.

7. Insert the new HEATER GUARD replacement filter cartridge: Place it into the blue housing, making sure that it slides down over the stem found at the bottom of the housing. The filter must be correctly positioned over this stem.

8. Close the filter housing: Position the top of the filter under the stem found in the base of the black cap, check that the O-Ring is correctly positioned, and twist the blue housing back onto the black cap. Hand-tighten this but avoid over-tightening.

9. Turn the water supply back on: Do this slowly to allow the housing to fill with water. Depress the RED pressure release button again to release any trapped air from the unit.

10. Check for leaks: This is to ensure that the filter is correctly installed and the housing is properly sealed.
