Setup and Installation

The Doulton Biotect Ultra filter element is intended for installation into compatible Doulton under-counter filter housings (e.g., HIP Inline, HIP DUO, HIP TRIO). Refer to the specific installation manual for your Doulton filter housing for detailed instructions.

General Installation Steps (for filter element replacement):

1. Turn off Water Supply: Locate the cold water supply valve leading to your filter system and turn it off completely.
2. Depressurize System: Open the filtered water faucet to release any pressure in the system. Allow water to drain until flow stops.
3. Open Filter Housing: Carefully unscrew the filter housing sump from the head. You may need a filter wrench.
4. Remove Old Filter: Remove the used filter element and dispose of it properly.
5. Clean Housing: Clean the inside of the filter housing sump with warm, soapy water. Rinse thoroughly. Inspect the O-rings for any damage and replace if necessary. Lubricate O-rings with food-grade silicone grease if needed.
6. Install New Filter: Carefully insert the new Doulton Biotect Ultra filter element into the housing sump, ensuring it seats correctly. The M12 thread on the filter should align with the corresponding fitting in the housing head.
7. Reassemble Housing: Screw the filter housing sump back onto the head. Hand-tighten, then use a filter wrench to tighten an additional 1/4 to 1/2 turn. Do not overtighten.
8. Restore Water Supply: Slowly turn on the cold water supply valve. Check for leaks.
9. Flush System: Open the filtered water faucet and allow water to run for at least 5-10 minutes to flush out any air and fine ceramic particles. Initial water may appear cloudy; this is normal and will clear.

Operating Instructions

Once installed and flushed, your Doulton Biotect Ultra filter operates automatically as water flows through your compatible Doulton under-counter system. Simply open your filtered water faucet to dispense purified water.

• Initial Use: After installation and flushing, the water is ready for consumption.
• Flow Rate: The filter may slightly reduce the flow rate of your filtered water faucet compared to an unfiltered tap. This is normal and indicates the water is passing through the filtration media.
• Taste and Odor: You should notice a significant improvement in the taste and odor of your drinking water.

Maintenance

Regular maintenance of your Doulton Biotect Ultra filter is crucial for optimal performance and longevity. The ceramic element is re-cleanable, allowing you to restore flow rate and extend its effective life.

Cleaning the Filter Element:

Over time, the outer surface of the ceramic filter may accumulate impurities, leading to a reduced flow rate. This indicates it's time for cleaning.

1. Turn off Water Supply: As with installation, turn off the cold water supply to the filter system and depressurize.
2. Remove Filter: Carefully remove the filter element from its housing.
3. Clean Ceramic Surface: Using a soft brush or a clean, abrasive pad (like a Scotch-Brite pad) and clean water, gently scrub the entire outer surface of the ceramic element. Do not use soap or detergents. Scrub until the white ceramic surface is clean and free of discoloration.
4. Rinse Thoroughly: Rinse the filter element under running water to remove all loosened particles.
5. Reinstall: Reinstall the cleaned filter element into the housing, following the installation steps outlined above.
6. Flush System: Flush the system for 5-10 minutes after reinstallation.

Recommended Replacement Interval: The manufacturer recommends replacing the Doulton Biotect Ultra filter element every 6 months or after filtering 2300 liters (approximately 12.6 liters per day for 6 adults), whichever comes first. Regular replacement ensures continued high-quality filtration.
