Section 1 Important Things to Consider
Water Supply (Water Fittings) Regulations 1999
Familiarise yourself with the requirements of the Water Supply Regulations 1999: www.legislation.gov.uk/
Maximum Working Pressure 6 bar/90psi.
Measure the pressure during the ‘low demand’ period, when the pressure will be at its highest- e.g. in the midmorning, mid-afternoon or late evening. If the pressure exceeds 6 bar/90psi, it will be necessary to install a
suitable pressure reducing valve in the supply line upstream of the filter stop valve.
Minimum Pressure 1.5 bar/23psi
This is the minimum pressure recommended to achieve an acceptable flow.
Filter Housing
The filter housing is precision engineered in 304 stainless steel and will require no routine maintenance beyond
regular lubrication of the large sump ‘O’ Seal (see Lubrication below) and an occasional wipe with a damp cloth.
Applying a smear of grease to the large ‘O’ seal on the head of the housing at each cartridge change will ensure
the two parts of the filter housing are easy to separate and re-assemble.
Important. Use only WRAS (Water Research Advisory Service) approved silicon grease to lubricate the rubber seals
as rubber and plastic parts will degrade and eventually fail if the wrong grease is used. A suitable grade of silicon
grease is available to purchase online at www.freshwaterfilter.com
Sensible Precautions
If you are planning to leave the premises where the filter is installed for an extended period, turn off the water
supply to the filter using the filter service stop valve, then operate the filtered water tap on and off again to
release the pressure in the system.
Section 2 Planning your Installation
Although your FreshWater system is designed for ease of installation, careful planning and preparation before
commencing the installation will ensure the procedure is straightforward and trouble-free.
Choosing the Location
When deciding where to position both the stop valve and the filter housing, bear in mind the need for easy
access to make future filter cartridge changes a simple process. Ensure the terminations of the two braided
flexible hoses are within easy reach of their respective connections to avoid stretching the hoses.
Installing the Filter System above the Ground Floor
Extra care should be taken when installing water appliances above the ground floor. To reduce the risk of
potentially catastrophic flooding, install an automatic shut-off device at the outlet of the filter stop valve.
Backflow Prevention
To comply with UK Water Supply (Water Fittings) Regulations 1999, a suitable check valve (non-return valve)
arrangement should be installed upstream of the filter stop valve.
Plumbing Connections
The stop valve supplied with the system is for connection to 15mm copper pipe. For alternative connection
options please contact Franke FilterFlow customer service.

Section 4 Installation
Shut off the mains water supply
Install the stop valve
The stopvalve (E) supplied is 15mm compression to a 1/2 inch BSP male. A suitable
tee piece will need to be plumbed in 15mm pipe work conveniently located within
easy reach of the inlet hose connecting nut. Note To simplify DIY installation a self
piercing valve is available as an alternative to the stop valve; visit
Fitting the filter housing bracket
Mark the positions for the two securing screws (F) and screw them in. Allow approximately 2 mm below the head of the screw to protrude to allow the bracket (K) to be
easily located on and off the screws.
Section 4 Continued—Installation
Note Depending on the nature of the cabinet it may be necessary to position a
batten behind the panel to make secure fixing. Remember the weight of the
housing will increase when filled with water.
Install the filter cartridge and assemble the filter housing.
Unscrew the housing to separate the head (E) from the sump (H).
Holding the head in one hand screw the filter cartridge carefully in place, being
careful not to over tighten it (see section 8 cartridge change instructions).
Reassemble the housing to the sump and hand tighten it firmly.
Connect the braided inlet hose to the filter housing and the stop valve
Select the braided hose (J). Connect the end with the 1/2” BSP female nut on
to the stop valve (K). Hand tighten the nut and use a spanner to tighten it a
further half turn to make a watertight seal - Do not over tighten
Connect the filter tap to the outlet of the filter housing
Refer to the separate tap installation instructions included with the filter tap
you have selected. Take the length of 1/4” diameter white tube supplied with
the filter kit. Connect one end of this tube to the filtered water inlet of tap in
accordance with the tap instructions.
Take the free end of the 1/4” diameter white tube and make the connection to
the push fit connector in the outlet of the filter housing.
Important note — make sure that the 1/4” tube is pushed fully home in to the
connector. Initial resistance will be felt as the tube engages the internal ‘O’
seal — continue to firmly push the connector past the seal to the final stop. As
a guide 10mm (3/8”) of the tube should enter the connector. Failure to fully
engage the connector may cause the joint to leak or possibly fail completely.
Turn the water on
Check to make sure all the connections are secure. Close the stop valve (E) and
turn the lever of your filter tap to the ‘ON’ position. Operate stop valve (E) to
turn on the mains water supply. Check that the filtered water is running from
the tap spout. Allow the water to run for 5 minutes to flush the system and condition the cartridge.
Important for optimum removal performance adjust the stop valve to set the
filtered water flow to fill a one litre jug in approximately 30 seconds.
Check the installation for leaks
Turn off the filter tap and carefully check the whole system for leaks, particularly at the connections to the stop valve, housing and tap. Turn on filter tap
and allow the filtered water to run for approximately 10 minutes to clear any
manufacturing or installation residues. Your FreshWater filter is now ready to
use (as a precaution we recommend checking for leaks again before retiring for
the night).
Section 5 Maintenance
Routine maintenance
Apart from scheduled filter cartridge replacement, the filter unit
will require very little routine maintenance beyond occasional lubrication of the head ‘O’ Seal.
Important, use only an approved silicon grease for this purpose– if
you are unsure which grease to use please visit the FreshWater website www.freshwaterfilter.com or contact customer service on 0845
177 0896.
Section 6 Frequently asked questions
Limescale still forms in my kettle
The Pearl cartridge supplied as standard with FreshWater systems will not reduce limescale. It are first and
foremost a health and security cartridge, designed to significantly reduce possible harmful waterborne
contaminants in both hard and soft water regions. Calcium and magnesium, the minerals associated with
limescale in water, are left intact as they are considered beneficial to health and contribute to its pleasant
taste. However, if the cosmetic concern relating to scale reduction is your primary concern, you can switch
to an Crystal cartridge on your next cartridge change date. Visit www.freshwaterfilter.com for more
information and to view the range of specialist cartridges.
Unsightly deposits on the surface of a cup of tea.
In hard water areas a ‘scum’ can appear on the surface of hot tea. Although unsightly it is completely
harmless. The cause is related to the precipitation of calcium and magnesium in hard water regions and a
reaction with the tea bag material. Changing tea bags will often remedy the problem. Alternatively you can
consider switching to a Crystal cartridge (refer to previous paragraph).
Milky water
With a new system a significant amount of air is trapped in the microporous structure of the cartridge. This
will form tiny bubbles and give the water in the glass a milky appearance that will soon disperse when left
to stand for a few moments. This may continue for 2 to 3 weeks until the cartridge is fully conditioned.
Tiny black specs in the water
Tiny black specs may appear initially in the water. These are harmless particles of carbon; residues from
the manufacturing process. Allow the filtered water to continue flowing for a while until they are
completely flushed through.
The filtered water flow slows to an unacceptable level
A significant reduction in flow is an indication that the ceramic shell of the cartridge is blocked with
contaminants. This often occurs soon after a new system is installed due to plumbing residues, solder fluxes
etc, becoming trapped on the surface of the filter cartridge. If this happens inside the recommended 6
month change cycle you may clean the cartridge to restore the flow. Remove the cartridge (refer to
cartridge change instructions), hold the cartridge under warm running water and abrade the outer surface
vigorously with a non soapy abrasive pad sufficiently to restore the white colour of the surface.
Section 7 Changing the cartridge
Cartridge Replacement Cycle
The recommended filter cartridge change cycle is 6 months
Important: The period between cartridge replacements is not guaranteed; it is an estimate based on filtering mains
water of average quality. Please bear in mind that water quality varies from locality to locality and situation to
situation. In areas with higher than average turbidity (particle contamination) more frequent cartridge changes may be
Before you begin
No special tools are required for this operation. All you will need is a suitable receptacle to catch any spillage and a
cloth or a sponge handy. A rubber glove is provided to hold the wet cartridge.
Lubricating the rubber seals
For ease of assembly we recommend that a film of silicone grease is applied to the filter housing ‘O’ Seal at least
every other cartridge change to maintain the smooth operation of the unit. Important note Only a WRAS approved
silicon lubricant should be used for this purpose. Small tubes of a WRAS approved silicon grease can be purchased from
FreshWater at www.freshwaterfilter.com
1. Locate the shut-off valve
and turn off the mains
water supply to the filter
2. Turn on the dispenser
tap to release the pressure in the system. Leave
the tap in the ‘on’ position.
Important note. If the
tap is not left ‘on’ the
pressure trapped in the
system will make it impossible to unlock the
filter housing sump from
the head.
5. Holding the sump
over the sink remove
the spent cartridge
and empty the water in the sump.
Dispose of the spent
cartridge. Place the
new cartridge in the
6. Refit the sump to the
housing head by engaging
the pins in the slots and
turning the sump to the
right until it is fully engaged.
3. Firmly grip the sump
with both hands. Turn to
the left and pull down.
The sump and the filter
cartridge should come
away together. The filter
canister will be full of
water so it is advisable to
position a bowl to catch
any spills.
4. If the filter cartridge does not
come away with the sump release
it with an index finger by pushing
down on the plastic rim.
7. Turn on the water supply and check the system
carefully for leaks. Leave the tap in the ‘on’
position and allow the water to run for a minimum of 10 minutes to flush the filter.
Check the flow rate. We recommend no more
than 30 seconds a litre for optimum performance.
If the flow is too fast it can be regulated by adjusting the stop valve.
