Select the filter cartridge options supplied for stages A or B in accordance with
your requirements.
Screw the thread of each filter cartridge into the relevant cap inside the filter
head until washer resistance is felt – do not over-tighten.
If there is less than 10 inches clearance below the base of the filter housing,
place the filter body in position over the cartridge before screwing the cartridge
into the cap.
Moisten the O ring on each filter body, check that it is located correctly and then
screw the body to the filter head. Hand tighten only.
2. Conditioning the Ceramic Cartridge
The filter system should now be ready for pressurisation. With the user tap in the
on position, gradually open the upstream isolation valve until the flow from the
tap has stabilised at the recommended flow rate.
Close the user tap and ensure that the system is watertight.
In order to remove any loose particles resulting from the manufacturing process
or from cleaning the cartridge, it is recommended that the first supply of filtered
water should be run to waste for 10 minutes.
For a new cartridge, the maximum flow rate will be achieved once the ceramic
filter cartridge has become fully saturated; to allow the cartridge to be
conditioned to the source water, allow the unit to stand unused for a further
24 hours and then run the first 15 litres of water to waste.
The filter is now ready for use
Due to filtration of particulate contaminants from the water during use, the flow
of the water from the filter may deteriorate over a period of time. To restore the
water flow to its normal level, simply remove, clean and replace the cartridge as
follows:
3. Servicing the Filters
It is important to wear rubber gloves or wash your hands thoroughly before and
after servicing the filter and cartridges.
Removal, cleaning and reinstallation/replacement of the cartridges is carried out
as follows:
With the upstream isolation valve turned off, vent any pressure by opening the
user tap.
Place a bowl under the filter body and, using the wrench provided; unscrew the
filter body which will be full of water. Lower the body into the bowl.
The cartridges can now be unscrewed from the cap and cleaned in accordance
with the distributor’s instruction or replaced as described in Section 1.4.
When the cartridge have been re-installed, wipe the filter housing clean with a
damp cloth and refill the filter as described in Section 2.
Cleaning/Sterilising the System
To clean the housing wipe externally with a warm damp cloth. The following
substances should be avoided:
•
Strong oxidising agents such as bleach or Milton solution
•
All strong acidic materials including some descalents
•
Strong alkaline material
A cartridge that has reached the end of its life would be indicated by a reduction
in the taste quality of the filtered water. The cartridge should be replaced in
accordance with the rated service capacity, which would typically give a period of
six months usage.
