b) After carrying out the condition-
ing procedure, turn off the tap so
the whole unit is fully under mains
water pressure and check the unit
very carefully for leaks. It is impor-
tant to check again after a few
hours in case there is a very slow
and small leak. A small saucer un-
der the filter will catch any drips,
and will enable you to confirm that
all is correct.

Operating Instructions
1: Routine use
Hold the tap lever down to turn on
the water flow. Run the water for a
few seconds before use.
The water flow rate should be kept
at around 1.5 litres per minute at 5
bar pressure for optimum perform-
ance (about 24 seconds to fill a
pint bottle). The flow may be re-
duced by partially closing the con-
trol valve on the line piercing as-
sembly.
During use, unwanted particulate
material will collect on the outside
surface of the ceramic membrane
and this will reduce the water flow
rate. If the line-piercing valve is
fully open and the flow rate be-
comes unacceptably low, this nor-
mally indicates that the filter
needs replacing.
Under normal conditions, after
3000 litres (over 800 gallons) of
water have passed through your
FW1000 or six months has passed,
whichever comes first.
With the FW2000 both cartridges
should be replaced after 6000 litres
(over 1000 gallons) have passed
through it, or every 12 months,
whichever comes first.
Whenever a cartridge is replaced or
the filter housing opened for in-
spection, please check carefully to
ensure that there are no leaks.
From time to time, should the ‘O’
seal become brittle, or break, or
cause a leak it will need replacing.
‘O’ seals should be wiped with
white petroleum jelly (Vaseline) to
help lubrication.

General information
1: Useful tips
With just the minimum of mainte-
nance
and
attention
your
FRESHWATER FILTER high quality
water purification system will give
you many years of excellent ser-
vice. The following tips may be
useful:
A.) NEVER install the filter where
the water can freeze, as this will
break the ceramic and may damage
the seals.
B.) Install the filter only on the
COLD water line, never on the hot
water line.
C.) Check the filter regularly for
water leaks as these may indicate
faulty installation or maintenance.
D.) Always use white petroleum
jelly (Vaseline) on the ‘O’ seals to
help lubricate them and enable the
housing to be opened more easily.
E.) Never run your fingers over the
stainless steel threads or edges of
the filter - they are razor sharp.
F.) Read this user guide carefully
and keep it - and the set of spares -
in a safe place.
G.)
For
optimum
performance
clean and replace the filters regu-
larly in accordance with the in-
structions.
2: Fault Finding
If you have any difficulty in install-
ing the filter on maintaining the
filter you may find the following
useful:
2.1: No Water
A.) Check that the main stopcock is
open and that the mains water is
still on.
B.) Check that the line-piercing
valve is open. (Turn anti clock-
wise.)
C.) Check that the dispensing tap is
open.
D.) Check that all the pipes are
connected correctly.
E.) Check direction of water flow
2.2: Low Water Flow
A.) Check that you have removed
all the wrapping from a new filter
cartridge.
B.) Low water pressure. During
periods of high water demand the
pressure may fall and so will the
water flow from the filter. Running
a bath, shower or appliance con-
nected to same line on which your
FRESHWATER FILTER
®
system is
connected may starve the unit of
water.
C.) During use, low water flow may
be an indication that the filter is
becoming blocked as it collects the
unwanted debris and pollutants
from the water.
D) Check that the line-piercing
valve is fully opened, or if there is
low flow at the time of installation
check that the line piercing valve
instructions were carried out cor-
rectly and that the water line has
been pierced fully. (Close the line
piercing valve fully and then open
it up again).
E) The filter system needs a mini-
mum
pressure
of
2
Bar
(approximately 29 psi) to work. As
a general rule, the higher the pres-
sure generally the greater the wa-
ter flow will be. If the pressure is
inadequate
a
pump
may
be
needed, and for this you should
contact the manufacturer or a
plumber.
