Check for leaks
- Slowly open the main water supply and press the red pressure relief valve to release trapped air until water starts to come out. Check whether faucets can discharge water normally.
- Check whether the connection points of the product are leaking or seeping slowly. If there is water leakage, check whether the connection is tightened. The recommended observation time is 5 minutes
- Make sure there are no leaks, rinse the product with tap water for more than 10-30 minutes before first use
FILTER REPLACEMENT
We recommend changing the filter every 3-6 month.
-
- Turn off the main water inlet valve and open the nearest faucet until the flow stops.
- Press the pressure relief valve to relieve pressure and use the wrench to unscrew the filter bottle to replace filter.
Be cautious when removing the bottle as it can be very heavy when full of water.
-
- Take out the used filter and throw it away. Remove seal ring, wipe it clean, and set aside. Wipe out the bottom of the filter bottle and bowl with nonabrasive sponge or cloth.
- Rinse it thoroughly. Insert the seal ring back into the groove and smooth into place with finger. Insert new filter in the bottom of filter bottle, making sure it is sitting upright (not tilted).
