ImPORTANT: 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
• 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
ImPORTANT: Always use gloves when replacing the filters. Replaced filters
should be disposed in a tightly closed garbage bag.
• Replacement of the 1st and 3rd stage 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 block carbon in the 3rd stage
filter cartridge), using the filter wrench, tighten the filter cover.
• Replacing the 2nd stage 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”
Warnings
• Notes before using replaced filters: After replacing the granular activated
carbon filter (2nd stage), 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 3rd stage filter or even
the RO membrane, which may result in damage to filter and membrane
components.
If there is dark colored water near the third stage filter, perform the
following steps:
- Turn off the water purifier inlet water valve;
- Using the filter cartridge wrench, remove the water purifier’s 3rd
stage filter;
- Place a large container near the 3rd 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 3rd stage filter into the filter
cartridge, and screw it in tight.
Please flush the post-activated carbon filter for 1-2 minutes before using.
• 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 25°C .
If net pressure is less than 0.5MPa or if the inlet water temperature is
less than 25°C, 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 3.6G.
However this figure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is app. 2.5-2.8G.
• 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.
