ball valve is open so the water purifier is in a working condition.

Maintenance and Upkeep

1. Flushing the RO Membrane

As water passes through the RO membrane, impurities and bacteria are retained on the membrane
surface, so you should regularly flush the machine to ensure that the RO membrane performance can
achieve the best results.

2. Filter Replacement Time

1. This machine's filter replacement cycle for the various filters is derived from statistical indicators on
average tap water use estimates. If there are big discrepancies between the user's actual water
quality and utilization rate and the average indicators, there will be more obvious differences
between the filter's actual use time and the estimated cycle such as premature filter clogging,
premature failure, etc. If this happens, filter replacement should be based on actual use, you
should also promptly contact your local after-sales service department.
2. This machine's estimated filter replacement cycle is based on average household water
consumption and is suitable only for residential use, do not install this machine in places that
require large volumes of water. If the water volume requirements are large, this company has
appropriate machines for business purchase.
3. According to economic statistics on municipal tap water, a three person family on average uses 10L
of water a day, according to the water volume and inlet water quality conditions, overall filter
volume is approximately as follows (the following data is for reference only):
Progression
First: 10-inch 5-micron PP filter
Second: 10-inch 85C granular activated carbon filter
Third: 10-inch CTO filter
Fifth: Post-activated carbon filter
Note: It is recommended that filter element replacement is carried out by after-sales staff.
Water quality has a great influence on the life of the filter, the RO membrane's lifespan is
affected by many factors, the above table expresses lifespan under standard conditions, in
actual usage, because the water quality may be different, the lifespan may exceed the above
estimate, it may also be lower than the estimate, this data is for reference only. Under normal
circumstances if the following situations are experienced, you should consider replacing the
filter:
◆ Poor water quality, taste declines, TDS value of water rises;
◆ Water flow is significantly reduced, check to see if the filter or membrane is blocked (and
determine that it was not caused by a temperature drop);
◆ If the filter's outer surface is covered in mud or the filter has significantly changed color;
◆ If serious filter clogging leads to no pure water from the water purifier.
