Filter Housing & Cartridges
The FW1000 cartridge
(Fig 4)
is a
multi-stage water treatment unit in
which the water enters the housing
and percolates from the outside
into the cartridge through the po-
rous ceramic. The first stage of
treatment
is
micro
filtration
through the ceramic membrane.
This cleanses the water of sus-
pended particles. Because of its
superfine filtration characteristics -
the porous ceramic is too small for
bacteria to penetrate - it also per-
forms a further essential function.
It actually disinfects the water by
filtering out at least 99.99% of any
bacteria that might have entered
the water supply from the mains.
The water flows through the porous
ceramic cartridge and then passes
through a number of special water
treatment media, which serve to
improve the taste and act against a
whole range of chemical contami-
nants. The stainless steel filter
housing (the container for the car-
tridge) comprises a sump, which
can be unscrewed from the head-
works. (The headworks incorporate
water inlet and outlet connectors.)
The housing is rendered watertight
by the housing seal
(Fig 5),
that
fits inside the headworks.
Be careful with the screw thread
sections in the stainless steel hous-
ing. They can be razor sharp. Never
run your fingers over any sharp
edge. Remember stainless steel is
used for sharp surgical instruments!
To seal the cartridges into the
headwork’s within the stainless
steel housing, the upper spigot/
thread of the cartridge threads into
the head-works using the candle-
sealing washer (5). THIS SEAL IS
ESSENTIAL TO THE CORRECT WORK-
ING OF THE FILTER.
Develop the habit of checking that
it is in place before you screw on
the cartridge when you clean or
change the cartridge.
Also in the headwork’s you will see
the unique speed fit connectors.
The diagram
(Fig 6)
, shows how
these work, you will see that it is
very simple to just push fit the
tube into the connectors but be
assured that this joint can with-
stand many times the pressure of
normal water supplies.
A Word of Caution!
The FW2000 system, which gives
additional performance and longer
cartridge
life,
comprises
two
stainless steel housings and two
different types of cartridge
(Fig 7)
.
Water flows through the first and
then through the second.
Filter cartridge Type A is similar to
the cartridge in the FW1000. It
consists of a first stage ceramic
membrane together with a series of
fine granular-form water treatment
media.
Filter cartridge Type B contains a
further series of different media
and is designed to operate only in
conjunction with cartridge Type A
to further remove water pollutants.
