Citric Acid cleaning cartridge set (product includes 2 filters: the citric acid cleaning filter, which goes on the left side, and one blank filter, which goes on the right.)
The H2 Series water ionizers have continuous-cleaning inside the water cell, but if your water flow-rate slows it may mean it's time to do a citric acid wash. People with hard water may need to do some kind of citric acid cleaning every year or so.
Using the Citric Acid Cleaning Cartridge makes it easier to clean the internal lines of the water ionizer than ever. All you need to do is install the special Citric Acid filter in the main filter spot (left side) of the ionizer and the blank one on the right. Then follow the directions, below.
Citric Acid Cleaning Cartridge Directions:
- Unplug the machine.
- Turn off the water supply to the machine.
- Open up the water flow valve.
- Open filter covers.
- Disconnect wire harnesses and remove both filters.
- Insert the special Citric Acid filter in the main filter spot (left side) of the ionizer and the blank one on the right..
- Insert cap (included) on the tip of the acidic-hose (grey hose) of water ionizer.
- Gently curl and tilt the Top Spout (flexi-hose) upward, so the tip of it is up above the height of the ionizer.
- Turn on the water flow valve (slow flow) until drips start to come out of the tip of the spout. Then turn it off immediately.
- Let it sit for a 5 hours, or overnight.
- When the time is up, set the flexi-hose back down into its normal spot and remove the plug from the end of the acidic hose.
- Turn on the water flow (machine still unplugged) and let it flow freely for 5 minutes.
- Remove the empty Cartridges and return the regular filters to their normal spots.
- Run water through the still unplugged machine for about 2 more minutes.
- Plug it in now and you're ready to go.
