• The Echo hydrogen water comes out of the top spout. Nothing comes out of the bottom spout. 

What would I use the hydrogen water for?

Hydrogen water is perfect for everyday hydration. Because adding molecular hydrogen (H₂) does not significantly raise or lower the pH, the water remains essentially the same pH as your source water. That means it's suitable for drinking throughout the day and can also be used when taking medications, unless your healthcare provider has given you different instructions.

Molecular hydrogen has also been the subject of a growing body of scientific research exploring its potential health and wellness benefits. While research is ongoing, many people choose to incorporate hydrogen water into their daily routine as part of an overall healthy lifestyle.

Alkaline Water Levels

pH levels will always vary with different source water. Alkaline Level 1 is one pH higher than your source water. Each level of alkalinity increases the water's pH by 1 pH unit higher than the last setting.

Level One: Weak Alkaline Water

• Has a pH of |8
• This level is used for the initial consumption period (4-7 days) for those who drink alkaline water. 
• Let your body adjust slowly to this increase in pH.

Level Two: Weak to Medium Alkaline Water 

• Has a pH of 9
• After the initial adjustment period, those who drink alkaline water should move up to this level, which they should adjust to for three to four days. 
• Alkaline water drinkers often consume level 2 or 3.

Level Three: Medium to Strong Alkaline Water

• Has a pH of 10
• If you choose to drink this level of alkaline water, you may start to detect a strong taste. 
• You may notice calcium buildup on glasses. You can clean it with vinegar.

Echo Ultimate™ Cleaning & Maintence Instructions

Regular cleaning is one of the best ways to keep your Echo Ultimate performing at its best for years to come. Using a cleaning cartridge helps remove mineral deposits, sediment, and other buildup that can naturally accumulate inside the machine over time. Keeping these internal components clean helps maintain optimal performance, supports consistent water quality, reduces unnecessary wear on the machine's internal mechanisms, and helps keep your warranty coverage intact.

Cleaning cartridges are sold separately and can be purchased anytime on our website here:

📘 Echo Cleaning Cartridge

For even greater convenience, we also offer subscription options so replacement cleaning cartridges are delivered when it's time for routine maintenance. It's an easy way to stay on schedule and help protect your investment without having to remember to reorder.

Recommended Frequency:

• Twice per year for normal water conditions

• Every 3 months in areas with hard water

Using a Cleaning Cartridge

1. Turn off the unit completely.

2. Remove the main TAG filter and place it in a container to catch any water.

3. Install the cleaning cartridge in place of the main filter.

4. Turn on the water (ON position) to let water flow through the machine until it exits from the top. Run each water setting for at least 30 seconds:

   1. Hydrogen (H₂)
   2. Alkaline
   3. Acidic
   4. Filtered
5. Turn off the water and let the unit sit overnight for deep cleaning.
6. The following day,  remove the cleaning cartridge and reinstall your main TAG filter.
7. Flush the unit by running filtered water for 3 minutes to remove any cleaning residue.

⚠️ If you see a "Non-authentic filter" message after installing the cleaning cartridge, don't worry—that's completely normal. Since the cleaning cartridge isn't your regular TAG filter, the unit may display that message temporarily.

1. To clear it, simply:
2. Turn the unit off and back on, or
3. Temporarily reinstall your main TAG filter, then switch back if needed.
4. A helpful tip: after you've completed the final 30-second flush on each setting, it's a good idea to discard that initial water. That ensures any remaining cleaning solution has been completely flushed from the system before you begin using it again.

Echo Ultimate™: Measuring the pH of the Water

 ✅ Note: Water quality and mineral content vary greatly in different Locations and will directly impact machine performance with respect to pH and hypochlorous acid production.

	Fill the test container provided about 1/2 full with alkaline, acidic, filtered water or H2 water.
	Add two or three drops of the pH reagent into the container and stir. If the reagent and water are not mixed well, an incorrect reading may occur.
	The pH value is determined by matching the color of the water to the pH color chart provided. A digital pH meter is more accurate than a reagent.

Important Safety Protocols

• DO NOT consume a water-containing pH reagent.
• Keep the pH reagent Liquid and color chart away from open flames!
• If the liquid comes in contact with the eyes, flush liberally with fresh water and seek medical help.
• If ingested, induce vomiting and seek medical help.

FAQs and Solutions

pH test shows alkaline water color as neutral (7), while acidic water color turns yellow (6). 

This is normal

Faulty or evaporated reagent: alkaline/acidity is always produced in inverse proportions. Therefore, showing an acidic color means that alkaline water has to be generated from the unit inversely. Lack of alkaline color can result from a chemical reaction where carbonic acid in water evaporates some of the test reagent elements.

• Test the pH value on level 3 or 4 water: replace the reagent.
• Test the TDS of the source water.
• The optimal TDS is 75-150 ppm.

1. Machine Will Not Turn On

Possible Causes

• The power switch is turned off

• The power cord is not properly plugged in

• The outlet is not functioning

• Blown fuse

• Internal power supply issue

What to Do

1. Check the power switch on the back of the machine

   • | = ON

   • O = OFF

2. Make sure the power cord is securely plugged into a working outlet.

3. Test the outlet by plugging in another appliance.

4. Check the fuse if the machine still does not power on.

How to check the fuse

• Locate the fuse holder above the power plug.

If the issue continues, submit a video through our support portal so our team can assist.

4. Water Smells Strange

Possible Causes

• Expired filter

• Sudden change in water quality

• Elevated sulfur levels (common in summer months)

What to Do

1. Replace the filter.

2. Try selecting a lower pH level (1–2).

Sulfur levels in municipal water can occasionally cause a temporary smell when electrolyzed. These levels may still fall within safe drinking standards.

5. Murky or Cloudy Water (White Particles)

Cause

High water hardness (calcium) in your source water. Electrolysis can cause calcium carbonate (CaCO₃) particles to appear as white, snow-like particles.

Is This Safe?

Yes. These particles are harmless calcium minerals.

What to Do

You can:

• Lower the alkaline setting to level 1 or 2

• Install a water softening pre-filter

6. Water Leaking From the Unit

Leak from Filter Housing

Cause: Filter not installed correctly.

Solution

1. Remove the filter.

2. Reinstall it carefully following the filter replacement instructions.

Leak From Tubing

1. Turn off the water supply.

2. Disconnect and reconnect the tubing firmly.

3. If leaking continues:

   • Trim ½ inch from the tube end using a razor blade.

   • Reinsert the tube securely.

Leak Message on Display

• This may indicate mineral buildup affecting the internal shut-off valve.

• Recommended step: Run a Cleaning Cartridge through the system.

• Cleaning should be performed every 6 months (or more often depending on water hardness).

7. No Acid Water From the Secondary Outlet

Cause

The bottom outlet hose may be bent, kinked, or restricted.

What to Do

• Straighten the hose

• Increase the water supply flow

⚠️ Note: When alkaline or acidic water is selected, the machine naturally produces water from both outlets in a 1:1 ratio. This is normal operation.
 

8. Faucet Does Not Turn Off, or Water Continues Running

Cause

Mineral buildup inside the valves prevents them from closing properly.

Solution

Run a Cleaning Cartridge to remove mineral deposits. Cleaning is recommended every 6 months.
 

9. “Non-Authentic Filter” Error

This usually occurs when the machine cannot properly read the filter chip.
