If you are considering carrying out the installation of your
FrankeFlow water filter as a DIY project, we respectfully
suggest you consider the risks associated with installing
water appliances. Franke recommend you engage the
services of a qualified installer to install and commission
your Franke FilterFlow system.
Please keep this guide in a safe place. It will enable you to get
the best performance from your FrankeFlow filter now and in
the future.
SECTION 1:
HOW THE SYSTEM OPERATES
The Franke FRF02 multi stage water filter cartridge* supplied
as standard with your FilterFlow mini system is capable of
removing a wide range of possible water contaminants.
*For Northern Ireland, Franke FilterFlow systems are supplied
with a Franke FRF01 filter cartridge, to suit local water
conditions.
The FRF02 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 FRF01 cartridge is an advanced carbon block with a white
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.
Your Franke FilterFlow water filter system is designed to connect
exclusively to Franke FilterFlow Mini filtered water dispenser taps.
The component parts of the system are precision manufactured to
the highest quality standard, using premium food grade materials.
Correctly installed and maintained your FilterFlow water filter will
provide many years of trouble free use and a convenient, secure
supply of high quality drinking water. Your Franke FilterFlow is
supplied as a complete system with the parts required for
connection to your Franke Mini dispenser tap and the cold mains
water, including a Franke multi-stage filter cartridge.

SECTION 2:
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. mid-morning, 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. (A suitable
pressure reducing valve is available online
at www.FrankeFilterFlow.co.uk/)
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. Under no circumstances should the housing come
in to contact with household cleaners as this may cause the
housing to fracture. 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 green flexible tubing
Although the tube can withstand significant water pressure do
not stretch , kink or expose the green 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. Turn
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 before use.
SECTION 3:
PLANNING YOUR INSTALLATION
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.
