Lotus 75 TC 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 is optimized.
• Flushing method: Automatic flushing.
• Flushing step: The membrane will be automatically flushed for
15 seconds each time the water purifier is turned on.
Filter Replacement Intervals
• The filter replacement cycles for the various filters used in this purifier is
derived from statistical indicators on the estimates of average tap water
usage. If there are considerable discrepancies between the users supply
water quality, utilization rates and average indicators, there will be more
obvious differences between the filters actual replacement intervals
and estimated life-cycles and users may experience premature filter clogging,
premature failure, etc. If this occurs, filter replacement intervals should be
based on actual usage conditions. You should also contact your local
after-sales service department immediately to inform them of the situation.
• 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, our company offers
appropriate equipment tailored for commercial applications.
• 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, approximate filtering
volumes are as follows (the following data is for reference only):
Important Note:
Water quality has a great influence on the life-cycle of the filters. The
lifespan of the RO membrane is affected by many factors.
The table above represents the lifespan of filters under standard
conditions. In actual usage, due to the fact that water quality may be
different, the lifespan of the filters may exceed or may be lower than the
abovementioned estimates.
The above data is provided for reference only. Under normal circumstances,
if you witness the following indications, you should consider replacing your
filters:
• Poor water quality, taste declines, TDS value of water rises TDS value of
water;
• Water flow is significantly reduced. Check to see if the filter or
membrane is blocked (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 flow from the unit.
