Instructions for renewing (regenerating) the resin in the limestone and nitrate cartridges

Limescale retention cartridge (blue base cover for the normal Olympus+ model and the yellow base cover for the GIGA model ), as well as the nitrate retention cartridge (red base cap for the normal Olympus+ model and the white base cover for the GIGA model ), requires resin regeneration as follows:

OLYMPUS NORMAL FILTER +:

For water with a hardness of up to 20-22 mg/L in German degrees, resin regeneration should be performed every approximately 350 liters of water.

OLYMPUS GIGA FILTER:

The same applies to normal Olympus + model. Resin regeneration should be carried out on approximately 350 liters of water with a hardness of up to 20-22 mg/l in German degrees.

ABOUT THE NITRATE BOX:

For nitrates up to 55 mg/L, the resin regeneration should be performed on approximately 150 liters of water. For nitrates above 55 mg/L, the regeneration procedure should be performed on fewer liters of water. The more often the procedure is repeated and the less water comes out of the filter tap, the better the nitrate reduction result will be for both our models (normal and GIGA).

To regenerate the resin on each cartridge so that it can again reduce calcium-magnesium or nitrate deposits, the following procedure must be followed:

1) We unscrew the cartridge from the device.

2) Fill a narrow, elongated container, with a capacity of 1-2 liters, with water and add 3-4 tablespoons of table salt, which we mix well to dissolve before inserting the cartridge inside (preferably coarse salt).

3) We immerse the resin cartridge in water, making sure it is 100% covered by the salt water.

4) After about 30-45 minutes, remove the cassette from the brine and, after rinsing the outside with tap water, place it back into the device.

5) We open the tap strongly for about 1 minute to rinse the box from the brine inside and that's it.

RESIN CASSETTE REPLACEMENT

The durability of the resin cartridge is 10-12 months (the same as the ceramic cartridge with activated carbon), so its replacement is mandatory.

How do I change the filter cartridge?

Unscrew the old cartridge and screw in the new one without tightening it. No tools required. Before first use, let the water run for 2-3 minutes to rinse the new cartridge.

How do I know which cartridge is right for me?

Check the color of the thread on your current cartridge. Olympus: green or black for chlorine, bacteria, pesticides, heavy metals and more, blue for limescale, red for nitrates. If you are unsure, call us at +359 2 492 8764 (English only).

How often should I change?

The cartridge is replaced every 12 months or every 8,000 liters of water, whichever comes first. In the meantime, it can be cleaned to extend its life.

SIMPLY BEAUTIFUL. I've had them for years, ever since they were given away for free as a promotional item. I've since bought four more. I highly recommend them.
