Before You Begin

Multipure Drinking Water Systems (DWS) have been extensively tested and certified by NSF International to ensure they perform as claimed. Read this manual carefully before installation and use. Proper installation, operation, and maintenance are crucial for system performance; failure to follow instructions may lead to product damage or failure.

• Replacement filters are available directly from Multipure. Visit www.multipure.com/store/ for the latest prices.
• Actual filter life depends on water usage and impurity levels. Refer to the "Regarding Filter Capacity" section for details.
• Multipure DWS are not intended for microbiologically unsafe or non-municipally-treated water. Systems certified for cyst reduction can be used with disinfected waters containing filterable cysts. See "Frequently Asked Questions" for more information.
• Do not allow water to freeze in the system. If exposed to freezing temperatures, drain the system and remove the filter. Allow the filter to thaw before replacing or reusing.
• Avoid letting water sit in the system for extended periods (over 10 days) without use. Refer to the "Flushing / Disinfecting the System" section for guidance.
• To dispose of a used filter, remove it from the housing and place it in normal refuse. Landfill disposal will not release chemical contaminants, and the filter may continue to adsorb contaminants.

Specifications

Inspect Your Drinking Water System

Before setting up and connecting your Aquaversa, inspect it to confirm it has been received in good condition and that all parts are included.

Install Your System

The Aquaversa is certified to be plumbed into a separate tap. It can be installed below the sink or on top of the countertop next to the sink. Refer to the Installation Guide included with your Accessory Kit for step-by-step instructions.

The Aquaversa can be used inline for connection to refrigerators, water coolers, or ice makers, filtering all water from the cold water outlet or faucet. Multipure recommends professional plumber installation for inline use.

Install Filter Cartridge

1. With the Aquaversa housing upright, unscrew the black knob on the Locking V-Band counter-clockwise.
2. Remove the black knob, spread the Locking V-Band apart, and let it drop off the bottom of the Aquaversa. Set aside carefully.
3. Lift the top half of the Aquaversa off the bottom half. Ensure the black O-ring remains in place on the bottom half.
4. Inspect the black rubber cushion inside the top half of the housing to ensure it is properly positioned.
5. If not already done, remove the new filter cartridge from its box and peel off the plastic wrapper and instruction wrap.
6. Align the threaded hole of the new filter cartridge with the inside thread of the top half of the Aquaversa.
7. Rotate the cartridge clockwise to tighten (if facing the inside of the top half). Ensure the cartridge is threaded properly and straight. DO NOT OVERTIGHTEN.
8. Reconnect the top half of the housing (with the attached filter cartridge) to the bottom half.
9. Replace the Locking V-Band, ensuring the screw is in place to connect the band.
10. Screw the black knob onto the Locking V-Band clockwise to tighten. Ensure the V-Band is securely and evenly tightened around the housing top and bottom.

Prepare Your System for Use

1. Using a paper towel or cloth, dry all connections and the system housing.
2. Ensure all connections are tightly secured.
3. Flush the system before use:
   • Allow water to flow through the DWS for 15 minutes to purge air and loose carbon.
   • Adjust water supply so flow to the drinking water faucet does not exceed 0.75 gallons per minute. (Note: It takes approximately 20 seconds to fill a quart at this flow rate).
4. Check all connections for leaks.
5. Congratulations! Your system is now ready for use!

Maintenance

Regarding Filter Capacity

Filter capacity varies based on water usage and impurity levels. For contaminants reduced via physiochemical adsorption, the capacity is 750 gallons. For mechanical filtration, capacity claims are inapplicable due to variations in water quality and physical matter. Excessive physical matter can clog the Aquaversa, reducing flow rate but also reducing contaminants.

For optimal performance and to maintain the system housing warranty, replace the filter when any of the following occur:

• Annually
• When the system nears or reaches its rated capacity
• When the flow rate diminishes
• When the filter becomes saturated with bad tastes and/or odors

Removing the Old Filter Cartridge

1. Before opening the Aquaversa housing, place a pan or basin beneath it.
2. Stop the water supply and relieve water pressure in the Aquaversa.
3. If the system is mounted on a bracket, remove it from the bracket by tilting the top towards the wall, sliding the locking V-Band up into the upper bracket notch, and then sliding the system out of the bracket.
4. With the Aquaversa housing upright, unscrew the black knob on the Locking V-Band counter-clockwise.
5. Remove the black knob, spread the Locking V-Band apart, and let it drop off the bottom. Set aside.
6. Lift the top half of the Aquaversa off the bottom half, ensuring the black O-ring remains in place.
7. Remove the old filter cartridge from the top half by rotating it counter-clockwise. Dispose of the used cartridge in your waste container.
8. Rinse the inside of the system housing, hand washing if necessary.
9. Inspect the black rubber cushion inside the top half for cracks or wear. Multipure recommends replacing the cushion every two to three years.

Installing the New Filter Cartridge

1. If not already done, remove the plastic wrapper and instruction wrap from the new filter cartridge.
2. Align the threaded hole of the new filter cartridge onto the inside thread of the top half of the Aquaversa. Rotate the cartridge clockwise to tighten. Ensure it is threaded properly and straight. DO NOT OVERTIGHTEN.
3. Reconnect the top half of the housing (with the filter cartridge attached) to the bottom half. Replace the locking V-Band, ensuring the T-bolt is oriented so it lies flat in the groove of the V-band.
4. Screw the black knob onto the Locking V-Band clockwise to tighten.
5. Ensure the V-Band is tightly secured evenly around the housing top and bottom.
6. To resume normal use, proceed to the "Prepare Your System for Use" section.

Flushing / Disinfecting the System

Multipure recommends not allowing water to sit in the system for extended periods without use. If the system is unused for over 10 days, it may need flushing/disinfection before resuming normal use.

1. Remove the filter cartridge as described in "Removing the Old Filter Cartridge".
2. Add 5 to 7 drops of bleach to the bottom half of the system.
3. Reconnect the top half of the housing without a replacement filter cartridge.
4. Turn on the water supply and allow the system to fill with the water/bleach solution.
5. Let the water and bleach flush out of the system.
6. Open, clean, and rinse the inside of the system.

Troubleshooting

Water flow is frequently interrupted by air

Purge any residual air from the system:

1. Turn the system housing upside down.
2. Turn on the filtered water faucet (either through the Aquaversa faucet or the diverter valve).
3. Allow water to flow for one minute.
4. Turn off the filtered water faucet.

Odor – rotten eggs, no discoloration on the filter

A rotten egg odor indicates the presence of H2S (hydrogen sulfide) gas in your water source. If H2S is present, it is recommended to rotate usage between two filter cartridges. When the system emits the rotten egg smell, remove the filter and allow it to dry upside down to dissipate the gas (it can be reused once dry). Use the second filter while the first is drying.

Odor – rotten eggs, with discoloration on the filter

A rotten egg odor signifies H2S presence. Filter discoloration can indicate the source:

• Orange/brownish colors: iron
• Blackish colors: manganese
• Slimy/blotchy colors: decaying organisms

If hydrogen sulfide causes filter discoloration and a strong rotten egg odor, the recommended solution is to change the filter cartridge.

Color – milky color in the water

Milky water is typically caused by air bubbles. Higher than normal water pressure can create these bubbles, but they do not affect system performance. Air may also result from municipal water supply conditions.

• For countertop systems: Turn on the water and engage the diverter valve while slightly reducing water flow. Lower pressure can prevent air bubbles.
• For below-sink systems: Adjust water pressure at the feedwater adapter below the sink.

Color – black color in the water

Black color is typically caused by residual carbon dust from the filter. Allow water to run through the DWS for approximately 15 minutes to flush the filter. Residual carbon dust may initially color the water black.

Flow rate – the water flow rate is slow

The filter restricts flow rate when clogged with particulates or other solid contaminants. When flow rate slows significantly, or after one year of use, replace the filter cartridge. If other water sources are active, turn them off to check if they affect the flow rate.

Taste/Odor – miscellaneous

The carbon block filter may be saturated with tastes and odors from treated water. To resolve this, change the filter.

Frequently Asked Questions

Will low pH or acidic water affect the filter?

No. Mineral components determine water pH, and dissolved minerals pass through the system unfiltered.

• pH 7 = neutral
• pH > 7 = alkaline
• pH < 7 = acidic

Does deionized water or soft water have an effect on Multipure water?

No. Multipure filters do not treat natural minerals dissolved in water, so water hardness or softness does not affect the filtered water.

Can the Multipure system be connected to an icemaker?

Yes, the Aquaversa can be connected to a sink, refrigerator, water dispenser, or icemaker.

Can the Multipure system be used during an emergency or when the water is turned off?

Yes. During an emergency or when the source water is off, you can hand pump or siphon water through the Multipure system.

CAUTION: The Multipure system is not intended for use with microbiologically unsafe water or water of unknown quality without adequate disinfection before or after the unit. To disinfect questionable source water, add 1/4 tsp. of household bleach per gallon of source water; the Multipure system will remove this solution during filtering. Hand pump kits and emergency kits are available from Multipure.

What causes white particles to appear in Multipure water when it is frozen or boiled?

Because the Aquaversa does not reduce natural minerals, these minerals may solidify when frozen and appear as white flakes or specks when melted or boiled. Many natural minerals are beneficial and not a cause for alarm. Minerals can be removed by reverse osmosis technology (available through the Multipure AquaRO Drinking Water System).

Why does the Multipure system reduce Volatile Organic Chemicals, but not natural minerals?

Minerals are dissolved in solution and lack physical size, allowing them to pass through the system unfiltered.

Should sediment be removed with a standard filter first?

In areas with excessive sedimentation, pre-filtration can help extend the filter's operational efficiency, but it is generally unnecessary. Multipure DWS utilize a double-filter mechanic; the outer pre-filter protects the solid carbon block from clogging with large sediment.

Why is the compressed solid carbon block filter more efficient than (loose) granular activated carbon filters?

Multipure's densely compacted solid carbon block filters force water through microscopic pores, which are smaller than those in granular activated carbon. This process more effectively reduces particulate matter and contaminants affecting water quality, taste, and odor.

What is the difference between a “water softener” and a Multipure Drinking Water System?

Water softeners adjust water hardness (mineral content) and are not designed to treat drinking water contaminants. Multipure systems do not remove dissolved minerals, as natural minerals are often beneficial. Soft water is suitable for bathing and laundering but not recommended for plants or lawns. Multipure recommends bypassing a water softener when installing your Multipure Drinking Water System.

Can the Multipure Drinking Water System be used with untreated water?

Multipure systems are designed for municipally treated water. They are not intended for microbiologically unsafe water or water of unknown quality without adequate disinfection. For questionable source water, add 1/4 tsp of household bleach per gallon; the system will remove this solution during filtering.
