Note: It is recommended that filter replacement is carried out by
qualified after-sales staff. 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. This 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 water purifier.
Filter Replacement Method
• Replacement of the 1st and 3rd stage PP filters
First of all close the inlet water ball valve. Using the filter cartridge
wrench, unscrew the 1st and 3rd stage filter cartridges. Remove the old
filters and take the new filters out of their packaging. Finally place
the filters in the filter cartridges (Note: place the 5 micron PP filter
in the 1st stage filter cartridge, the CTO block carbon in the 3rd stage
filter cartridge), using the filter wrench, tighten the filter cover.
• Replacing the 2nd stage granular activated carbon filter
First of all, close the inlet water ball valve. Using the filter cartridge
wrench, unscrew the 2nd stage filter. Remove the old filter and take
the new filter out of its packaging (note: the rubber pad on the filter
does not need to be taken off). Place the filter inside the filter cartridge
(note: the granular activated carbon filter should be placed with the
rubber pad end directed up towards the filter covers) . Finally, use
the wrench to tighten the filter cover.
• For replacement of membrane elements please see
“RO Membrane Installation”
Notes
• Notes before using replaced filters: After replacing the granular activated
carbon filter, you must first flush out the machine in order to avoid
the activated carbon powder from the granular activated carbon filter
from flowing into the third stage filter or even the RO membrane, which
may result in damage to filter and membrane components.
Perform the following steps:
- Turn off the water purifier inlet water valve;
- Using the filter cartridge wrench, remove the water purifier’s third
stage filter;
- Place a large container near the third filter cartridge cover to collect
the dark colored water;
- Open the inlet water valve, wait until the water is no longer dark;
- Close the inlet water valve, reinsert the third stage filter into the filter
cartridge, and screw it in tight.
Please flush the post-activated carbon filter for 1-2 minutes before using.
• Other considerations:
- RO membrane water production volume
The water output volume of the RO membrane component is
influenced by inlet water pressure and water temperature.
Your equipment’s declared volume of 75GPD is tested under a net
pressure of 0.5MPa and inlet water temperature of 25C .
If net pressure is less than 0.5MPa or if the inlet water temperature is
less than 25C, water output volume of the RO membrane component
will be less than 75GPD.
- Storage tank capacity
The storage tank on your equipment has a stated capacity of 3.1G.
However this figure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is 2.0-2.5G.
- Disposal of old filters
After replacing old filters, they cannot be cleaned and reused; it is
recommended that you dispose of them with solid waste garbage.
