1) Starting for the First Time
A. To start the system, first plug it in and turn on the feed water adapter. Then turn on the
faucet. Vibrations can be expected as the pump starts.
B.
Turn on the faucet and let it run for at least 30 minutes to flush the system. This should be
done each time the filters are changed. Let the system run as much as possible to remove
preservatives of the RO membrane on the first day, and do NOT use the tap water for
drinking during this period. Alternatively, users can flush the system for 20 minutes every 2
hours after installation, repeating the process 12 times or more.
C. During this process, carefully check all fittings for secure connections. Use a damp paper
towel to wipe clean and verify that no connections are leaking.
D. Once the rinsing is completed, turn the faucet off and check again for leaks. If no leaks are
present, the system is ready for use.
2) Routine Maintenance
• If you plan on not using the system for one week or longer, take out the filter and seal it
with plastic wrap. Store the sealed filter in the fridge to protect the system against
microbiological growth. To start the system again after the period of non-use, flush the
system for at least 10 minutes OR change the filters.
• If you discontinue using the system for an extended time, disconnect the water supply, drain
the system, and disconnect the power.
• Follow the recommended filter replacement schedule. Replace the filter any time the
indicator is on. Note that the actual filter life depends on the number of people in the
household and water source quality. Failure to replace the filter at the appropriate times can
damage the system and potentially cause health hazards.
3) Changing the Filters
A. Disconnect the water supply and turn on the faucet to drain the remaining water in the
system.
B. Unscrew the filter to be replaced counterclockwise and relieve the pressure. (A small
amount of water leaking from the old filters is expected due to the pressure.)
C. Screw the corresponding replacement filter into each slot.
