How To Replace The RO Membrane Filter Element
1. Your Reverse Osmosis membrane usually has a useful life of about 2-3 years. The useful
life of filter membrane depends on the quality of source water, household water consumption
and the frequency of replacing 1st to 3rd filter element.
NOTE: In order to ensure the
performance of the system and the purity of water, please replace the 1st to 3rd filter
element as planned.
2. Please open the RO water faucet to reduce the system pressure, and place a towel under
the machine. It is a good idea to have a bucket handy to dump the water in the filter housing.
Note: When you unscrew the filter cap from the RO membrane filter housing, water will
be present in the filter housing. Place a water bucket close to the RO filter cap to
capture any water which may spill.
3. Remove the PE tube from the RO filter housing and unscrew the filter housing counter-
clockwise with the housing wrench.
4. It may be necessary to remove the RO filter membrane with a pair of pliers. Carefully pull
on the filter end to slide the filter out of the filter housing.
Note: The RO filter has a very
tight fitting inside the RO filter housing. Pulling out the RO filter membrane can be
difficult.
5. Inspect the inside of the RO filter housing. Please rinse the inside of RO filter housing
thoroughly with warm soapy water. Use a small amount of dishwasher detergent to clean the
inside of the RO filter housing.
6. Open the vacuum-tight package of the new reverse osmosis membrane, remove the RO
membrane and insert it into the filter housing.
Note: Please try to avoid touching the filter
membrane with your bare hands. Using a paper towel to wrap around the end of the
filter to help you install the filter.
7. Inspect the filter cap O-Ring and internal O-Ring. Make sure both are present and installed
correctly.
Note: We recommend replacing the O-Ring every 3-years to prevent water
leaks caused by an aging O-Ring.
8. Install the RO membrane housing cap and pre-tighten it by hand, and then tighten it by
1/4-½ turns with a housing wrench, without over-tightening.
Replacement of the 5th Stage Post Carbon Filter Element
Note: Please replace the post carbon filter element every 12 months. To help you
remember when the filter was installed, mark the outside of the filter housing with
the installation date.
1. Remove all tubes connected to the post carbon filter housing.
2. Replace the whole filter (including the housing) with a new one, then reconnect the tubes.
