How to Replace the Filters on Your Echo RO Unit

Replacing the filters on your Echo RO unit is an important maintenance task to ensure continued clean, great-tasting water. Follow this guide to replace the filters safely and effectively.

What You’ll Need:

• New filters (specific to your Echo RO model)
• A towel or bucket (to catch any water drips)
• Wrench (Optional* for additional Leverage)

Steps to Replace the Filters:

1. Turn Off the Water Supply:

• Locate the water supply valve connected to your Echo RO unit.
• Turn it off to stop water flow while you replace the filters.

2. Release the Pressure:

• Important: Shut off the source water valve.
• Open the faucet connected to your Echo RO until “Water Lack” appears on the screen.
• This is crucial: Failing to release the pressure may damage the unit and Void Warranty.

3. Remove the Filters from Housing/Unit:

• Unscrew the filters from the housing/unit by turning them counterclockwise.
  • They will turn about 90 degrees before releasing.
  • You may use a rag for a better grip if needed. (Wrench can be used to grab top of filter for additional leverage)
• Be prepared with a towel or bucket to catch any water that spills from the bottom of the filters.

4. Remove the Old Filters:

• Carefully take out the old filters from the housings.
• Pay attention to the order and orientation of the filters so you can replace them correctly.

5. Install the New Filters:

• Insert the new filters into the housings in the same order and orientation as the old ones.
• Ensure they are seated properly, with the numbers facing the right side of the unit.

6. Reattach the Filter Housing:

• Screw the filters back onto the housing/unit securely; 90 degrees clockwise.
• Do not overtighten to avoid damaging the housing or O-rings.

7. Turn On the Water Supply:

• Slowly turn the water supply back on.
• Check for any leaks around the filter housings. If no leaks are present, you're good to proceed!

8. Flush the New Filters:

• The unit will automatically flush the new filters.
  • If it doesn’t, select the flush option manually.
• Open the RO faucet and let the water run for 5-10 minutes to flush out air and loose carbon particles.
• This step ensures your water is clean and tastes good.

9. Check Your System:

• After flushing, check the water flow and taste.
• Everything should be running smoothly with no strange tastes or reduced flow.

Reset the Filter Life Indicator:

After replacing the filters, follow these steps to reset the individual filter life indicators:

1. Press ‘Select’ for 3 seconds to enter selection mode.
2. Tap the ‘Select’ option until you reach the filter you wish to reset.
3. Press the ‘Reset’ button. The Filter Life Indicator Rectangles will light up fully, indicating the reset is complete.
   

Final Check:

Ensure the water flows well and tastes good after flushing, and that the filter life has been reset. Your Echo RO unit should now be ready for use!
