cartridges, remove the old filters, then take the new filters out of the packaging, finally place the
filters in the filter cartridges, using the filter wrench, tighten the filter cover.
2. Replacing the 2
First close the inlet water ball valve, using the filter cartridge wrench unscrew the 2
remove the old filter, then take the new filter out of its packaging (the rubber pad on the filter does
not need to be taken off), finally place the filter inside the filter cartridge (note: the direction of the
granular activated carbon filter should be with the rubber pad end up towards the filter covers), use
the wrench to tighten the filter cover.
3. Replacing the 3
First close the inlet water ball valve, using the filter cartridge wrench unscrew the 3
remove the old filter, then take the new filter out of its packaging (the rubber pad on the filter does
not need to be taken off), finally place the filter inside the filter cartridge, use the wrench to tighten
the filter cover.
4. For replacement of membrane elements please see "RO Membrane Installation" (Page 10).

4. Notes

(1) Notes before filter use:
When replacing the granular activated carbon filter, first flush the machine in order to avoid activated
carbon powder from the granular activated carbon filter from flowing into the third stage filter or even
the RO membrane, resulting in filter and membrane component damage. Do the following:
1. Turn off the water purifier inlet water valve;
2. Using the filter cartridge wrench, remove the water purifier's third stage filter;
3. Place a large container near the third filter cartridge cover to collect the black water;
4. Open the inlet water valve, wait until the water is no longer black;
5. Close the inlet water valve, reinsert the third stage filter into the filter cartridge, and screw it in tight.
For the post-activated carbon filter please flush for 1-2 minutes before using.
(2) Other considerations:
1. RO membrane water production volume
The RO membrane component water volume is influenced by the inlet water pressure and water
temperature, this machine's stated volume of 500GPD is tested with net pressure of 0.5MPa and
inlet water temperature of 25℃, if the net pressure is less than 0.5MPa or if the inlet water
temperature is less than 25℃, the RO membrane element water production will be less than
500GPD.
2. 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.
Notes
★ When any of the following situations occur, immediately disconnect the water purifier
water source (close the inlet water ball valve) and/or the power source and carry out repairs.
· If the water purifier pipes or related components are leaking.
· If the water purifier's related components stop working.
· If any components leak electricity.
· If there are any other anomalies or failures.
★ When you go out or do not use the machine, disconnect the water purifier water source
(close the inlet water ball valve) and/or power source.
