Flushing All Filters in System
Now that Stage 1 – 3 filter are flushed, we will now need to flush out the RO filter membrane.
Please read through the following steps.
1. With the RO filter installed, open the RO fresh water storage tank water valve, turn on RO
drinking faucet, open the water inlet valve slowly check for water leaks. If so, check for the
following:
• The PE water tube is not completely inserted into the quick connector.
• O-Ring in the filter housing is not in the proper position or twisted.
• Filter Housing/cover is not properly tightened or not aligned with threads.
2. Please close the RO fresh water storage tank valve, RO water will slowly drip out of the
drinking faucet, keep the drinking faucet draining for at least 15-minutes to flush the whole
filter element system. NOTE: It is important that the RO Fresh Water Storage Tank water
valve is in the CLOSED position during the 15-minute flush process.
3. After 15-minutes, please close the RO faucet and open the shut off valve of the RO fresh
water storage tank. The RO fresh water storage tank will begin to fill with fresh RO water.
Note: This process may take 1-2 hours, depending on your water temperature
(40F-100F, the higher the temperature, the faster the speed) and source water TDS (max.
750ppm, the lower the TDS, the faster the speed). After the storage tank is full, the unit
will automatically shut down.
4. After the storage tank is full, turn on the RO faucet to completely drain the first storage tank
to empty, when no water comes out from the RO faucet, it means the tank is emptied. Then
turn off the RO faucet to let the system start producing RO water again.
5. NOTE: It is very important to check for water leaks every day for the first two weeks
after installation to ensure the normal operation of the system.
