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-after­noon or late evening. If the pressure exceeds 6 bar/90psi, it will be
necessar y 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

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.
