Gold Nano Filtration Replacement Filter Set


Filter Description:

Stage 1: 1um (Micron) Sediment Filter:
This removes particles from the water down to 1 micron.

Stage 2: Premium KDF Filter:
This filter contains activated carbon mixed with KDF. The KDF has anti-bacterial properties and prevents the growth of bacteria within the filter, thus extending its life to twice that of standard activated carbon.

Stage 3: 0.2 Micron Pleated:
This is a physical barrier that will not allow bacteria to pass through. 0.2 Micron Pleated Filter has replaced the Ultra Filtration Membrane as it dramatically reduces flush times making the system quicker to install and easier to maintain.

Stage 4: Nano Membrane
Removes Bacteria, Viruses, and Reduces the Mineral Content (TDS) by up to 50%.This filter has a life span of 2-3 years. This is an optional extra.

Stage 5: T33 Filter
Removes any smells or taste left in the filtered water. It will also absorb the preservatives found in the RO membrane after new installs.


Flushing the system:

This is done by running water through the system until the ceramic dust cannot be detected in a sample glass of water. Please note if there is a white colour to the water that settles out towards the top of the glass, this is most likely caused by tiny air bubbles in the water. This should subside over time as excess air in the system is removed. The air bubbles in the water will not affect the quality of your drinking water.


How to remove / replace your filter:

Start by unscrewing the filter housing from the filtration unit. This is done by rotating the filter housing in a clockwise direction (see diagram below). The filter housing will separate from the filtration unit, and you are now free to remove the filter cartridge from the filter housing. To replace your filter: insert the new filter into the filter housing. Be sure to remove any protective plastic wrapping from the filter cartridge before placing them into the filter housing. Check that the black rubber O-rings are in place and fit well on the filter housing. If they seem perished or loose you may want to purchase new O-rings to ensure a good seal. As an option you can add a little bit of Vaseline on the O-rings to make them seal better, this will make it easier to open next time. Take note of the single rubber seal on the one side of the Premium KDF.  These will need to face upwards to connect and seal at the top of the filter housing. It is important that this is done correctly as the system will not work optimally if the filters are installed incorrectly. Now that your filter is in the housing, bring the housing to the filtration unit and begin to screw the two together. This is done by rotating the filter housing in an anti-clockwise direction. We recommend you tighten by hand as this is usually sufficient to maintain a good seal. If however, leaks are detected, the housing spanner can be used to tighten the filter housings until a good seal is achieved. (Check O-rings are correctly in position before tightening with the spanner) Please take care not to over-tighten the filter housings. This could strip the housing thread and cause your system to fail. It will also make it more difficult to replace filters in the future if they are over-tightened.


How to Change the T33 Cartridge:

With these cartridges you will have one of two connectors used; the Jaco Connectors, which unscrew, much like your standard hose pipe fittings. And the Quick Connectors, these use a small blue safety clip to keep the pipe in place. The cartridge connector may vary from time to time due to product availability at different suppliers. So you may find yourself with a cartridge that has different connectors to your current setup. Do not fret, they are both compatible with the flex-hose used on the RO Systems. If you have a different connector on your new cartridge, you may remove the old connector from the old cartridge, and fit them to the new cartridge. This is a simple process of unscrewing the old connector and screwing it onto the new cartridge. Thread Sealing tape is a must when refitting connectors. This tape is available at most hardware stores. Once you have your desired connectors installed you can now assemble the system. With Jaco fittings the “Nut” is placed over the hose, the hose is inserted into the connector, then the “nut” is pulled towards the connector over the hose and screwed tightly. With the quick connectors, the blue clip is removed to allow the hose to be inserted or removed. Once the clip is off, you can push the hose into the connector. You should feel the hose slide in slightly at first, this is only in half way, more pressure must be applied to the hose to nest it fully in the connector. Once the hose is pushed into the connector tightly, the blue safety clip can be replaced. Please take note of the blue safety clips position on the connector. It must sit behind the movable part of the connector. This will secure your hose. If you have trouble fitting the hose into the connectors, this could be caused by previous connectors having damaged the hose. Simply cut the hose so that the end does not display any signs of use. This should aid in installation.

When to change your filters:

Filter life span is determined by the quality of the source water that runs through them. So if your source water is of a very bad quality, your filters will be doing more “work” to clean the water that is flowing through them. Thus depleting sooner than filters running under good water conditions. So in short each end-users filter requirements will be different as their source waters are different. We advise you check your filters on a monthly basis after initial install to get a feel for the quality of the water in your area. You will see for example, that the stage 1 filter (1um Sediment) is turning brown from the outside towards the centre over a period of 12 months. If this is the case your water quality is exceptionally good as these filters generally only have a life span of 4 - 12 months filtering average South African water. If your water quality is very poor you may be replacing the 1um sediment filter every 2 months. So visual inspection of your filters is the best way to determine when to change your filters. For the Premium KDF filter the “symptoms” are a little different. The KDF Cartridge will last anything from 8 to 24 monthes before needing to be replaced. These filters are depleted once bacteria has colonised them completely. So in testing you will want to see if any traces of bacteria can be detected. This is done by physically inspecting the filter cartridges. You want to check for a “slime” on the filters. This is a slippery substance and will feel similar to a mucus of sorts. If this is present on your filter cartridge then bacteria has colonised the filter and a replacement cartridge is required. When changing the KDF Cartridge it is the ideal time to replace the Ceramic and possibling the 1 Micron Sediment as well. The Pleated Filter can also become clogged, if you are noticing a much lower flow rate on your product water side of the system, this could be the cause. In which case the Pleated Filter may need to be replaced before the KDF. 

How To Install The Filters


Adding a Housing Spanner

Over time the housing can become tight, and difficult to open by hand. If you do not already have one available to open the housings, we would recommend adding a housing spanner. 

The Housing Spanner will allow you to gain more "purchase" on the housing, allowing you to open it more easily.
