SECTION 1:
HOW THE SYSTEM OPERATES
The Franke 02 multi stage water filter cartridge* supplied as
standard with your FilterFlow Zurich is capable of removing a
wide range of possible water contaminants.
* For the Republic of Ireland, Franke FilterFlow systems are
supplied with a Franke Franke 01 filter cartridge, to suit local
water conditions.
The Franke 02 cartridge comprises an outer shell of micro porous
ceramic enclosing an inner section of composite carbon block.
This ceramic and carbon combination will reduce sediment,
harmful bacteria, cysts, chlorine and lead.
The Franke 01 cartridge is an advanced carbon block with a red
pre-filter wrap and mesh. This cartridge will reduce sediment,
cysts, chlorine and lead and is suited to areas with low flow and
high levels of sediment.

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/uksi/1999/1148/
contents/made
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 mid-morning, mid-after-
noon 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.
A suitable pressure reducing valve is available online at
www.FrankeFilterFlow.co.uk/accessories

3
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 ABS plastic 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.
Important notes. Under no circumstances should the housing
come in to contact with household cleaners as this may cause the
housing to fracture. Plastic materials will degrade over time. Do
not install the housing where it is permanently exposed to
daylight, as over time extended exposure will degrade the plastic.
As a precaution the housing should be replaced every 10 years.
Taking care of the blue flexible tubing
Although the tube can withstand significant water pressure do not
stretch , kink or expose the blue plastic tubing to a naked flame
during installation. Do not allow the tube to come in to contact
with solvents and proprietary cleaners.
Lubrication
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.FrankeFilterFlow.co.uk
Periods away from home.
If you are planning to leave the premises where the filter is
installed for an extended period it is advisable to isolate the filter
system. Turn off the water supply to the filter using the filter stop
valve. Operate the filtered water tap on and off a few times to
release the pressure in the system. When you return just turn the
water supply back on and run the water for a few minutes.
Although your Franke FilterFlow 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
Choose the most convenient place to tee into the 15mm cold
water supply to install the stop valve. Decide the best place to
position the filter unit within the kitchen cabinet. Bear in mind the
need for easy access to make future filter cartridge changes a
simple process. Ensure the braided flexible hose and the flexible
plastic tube can be fitted without stretching or kinking.
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 pipework. For alternative connection options
please contact Franke FilterFlow customer service.

Note. Depending on the nature of the cabinet it may be necessary to position
a batten behind the panel to make a secure fixing. Remember the weight of the housing will
increase when filled with water.
Install the filter cartridge and assemble the filter housing
Unpack the new filter cartridge (L) and screw it into the housing head. Hand tighten the
cartridge sufficient to make a watertight seal.
Important. Do not overtighten the cartridge. Over tightening may shear off the threaded
section of the cartridge.
Connect the filter housing to the filter tap
Take the grey 3/8” push-fit connector (A) fitted to the free end of the blue plastic tube (B).
Locate the 3/8” diameter stem attached to the base of your FrankeFlow filter tap. Wet the
stem with a little water. Engage the push fit connector on to the end of the stem and push it
fully home.
Important note—making the push-fit connections. Make sure that the connector is
pushed fully home on the 3/8” stem. Initial resistance will be felt as the stem engages the
internal ‘O’ seal. It is essential to continue to push the stem fully home to the final stop to
make a water tight seal. The stem should enter 10mm (3/8”) when fully engaged. Failure to
fully engage the connector may result in a water leak or failure of the joint.
Turn the water on
Check to make sure all the connections are secure. Close the stop valve and turn the lever
of your filter tap to the ‘ON’ position. Turn on the mains water supply and turn on the filter
system stop valve. Check that the filtered water is running from the tap spout. Allow the water
to run for a minimum of 5 minutes to flush the system before drinking the filtered water.
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 the filter tap and allow the filtered
water to run for approximately 10 minutes to clear any manufacturing or installation residues.
Your Franke FilterFlow water filter is now ready to use (as a precaution we recommend
checking for leaks again before retiring for the night).
Connect the filter housing to the stop valve
Select the stainless steel braided inlet hose (G). Connect the end with the
1/2”BSP female nut to the male thread of the stop valve (H). Tighten the
nut with a suitable spanner sufficient to make a watertight seal.
Important. Do not be tempted to over tighten the nut as it will distort the
washer and cause the joint to leak.

Limescale still forms in my kettle
The Franke 02 and Franke 01 cartridges supplied as standard with
Franke FilterFlow systems will not reduce limescale.
They 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 Franke 05 Carbon DeAlk cartridge on your next
cartridge change date.
Visit www.FrankeFilterFlow.co.uk 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 Franke 05 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 specks 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
Franke 02 cartridge- 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.
Franke 01 cartridge – The Franke 01 cartridge is not cleanable
and will therefore need to be replaced once it becomes blocked
with contaminants.
SECTION 6:
MAINTENANCE
Routine maintenance
Apart from the scheduled filter cartridge replacement, the filter
unit will require very little routine maintenance, beyond occasional
lubrication of the head ‘O’ Seal (K).
Important. use only WRAS approved silicon grease for this
purpose – an approved grease is available to purchase from Franke
FilterFlow; visit www.FrankeFilterFlow.co.uk or contact customer
service on 0808 165 0008

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 necessary.
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
Franke FilterFlow at www.FrankeFilterFlow.co.uk
Disposing of the Spent Cartridge. You may dispose of the
cartridge in your normal household waste. Both the ceramic and
carbon components of the Franke 02 & Franke 01 cartridges are
biodegradable. You are welcome to return either the plastic parts
or the complete cartridge to Franke FilterFlow for recycling.
Should you decide to return the cartridge please allow it to dry
naturally and return it in the original packaging.
1. Locate the shut-off valve
and turn off the mains water
supply to the filter housing.
4. Hold the housing over
the bowl and continue to
unscrew sump. Carefully
remove the sump and
empty the water it
contains. Set it to one
side. Unscrew the filter
cartridge and discard it.
7. Turn the water supply ‘on’ and check the system carefully for
leaks. Leave the filter tap in the ‘on’ position and allow the water
to run for a minimum of 10 minutes to flush the system. 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.
6. Screw the sump to the head
and tighten it firmly. Re-mount
the assembled housing on the
two retaining screws.
5. Screw the new cartridge in to
the head. Tighten it firmly to
make a seal. Do not over tighten
as this may cause the threaded
section to shear.
2. Activate the filtered water
lever to “ON” 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.
3. Have a bowl to hand. Grip the
sump firmly and turn it to the left,
just sufficient to break the seal.
Lift the filter housing assembly off
its two supporting screws.
