2. Ensure that the cold water at mains supply
is turned off
Where an existing tap and connections are
already installed - after you have turned off the
mains cold water at the mini cistern tap, open
the kitchen / mixer tap and release any water
pressure.
Unscrew the braided flex hose from the existing
cold water line mini cistern tap or isolation valve.
Clean the ½” male water connection thread.
3. Undersink Mounting Position
As you will note from the associated diagram,
the WFA HiFlow filter system can be installed
in either the horizontal or vertical position.
a)
Vertical Installation
Measure 51 cm from the base of the cabinet
(or shelf), and mark the mounting location
for the top of the filter head. Make sure that
there is adequate space to avoid crimping
the water line flex hoses. Also make sure
your chosen location offers easy access for
future cartridge changes.
b)
Horizontal Position
Measure 51 cm
horizontally, and mark the mounting location
for the side of the filter head and end of the
filter cartridge. Make sure that there is
adequate space to avoid crimping the water
line flex hoses. Also make sure your chosen
location offers easy access for future
cartridge changes and installation of the
stabilizing support bracket. (item 7).
4. Important - Changing the inlet and outlet on
the filter head. You will notice that at the top
of the Head Assembly (item 1) there is an
arrow that indicates the direction of flow into
and out of the filter head. In some instances,
to ensure an easier installation, it may be
appropriate to have the inlet side on the right
of the head assembly as opposed to the left
hand side which is provided as standard.
This can be easily done by removing the four
(4) screws on the top of the head assembly,
turn the head around the opposite way and
replace the screws ensuring a tight fit. This
allows flexibility when choosing your desired
install location
.
a) Apply plumbing tape (item 9) to the Pex Hose
3/8” male connection (item 5). Wrap tape in
direction of the thread to ensure a tight fit
and avoid leaks. Screw this connection to
the inlet side of the filter head. You will
notice an arrow on the top of the filter head
(item 1) which shows direction of water flow.
b) Apply plumbing tape to the Brass Hex Nipple
(item 6) both sides. Wrap tape in direction of
the thread to ensure a tight fit and avoid
leaks. Screw this connection to the
outlet side of the filter head (item1).
c) Securely mount the Filter Head Assembly
(item 1) on the cabinet wall using two of the
mounting screws (item 3) provided. The filter
head will be installed vertically or
horizontally depending upon your desired
location.
5. Connect Dual Check Valve – (item 4)
IMPORTANT – It is a legal requirement under
Australian Plumbing Standards that the Dual
Check Valve be installed. If this part is not
installed all warranties are null and void.
a) Apply plumbing tape (item 9) to the ½” male
water connection cistern tap fitting before
screwing on the dual check valve (item 4).
b) Also apply plumbing tape (item 9) to the ½”
male connection on the outlet of the dual
check valve. Wrap tape in direction of the
threads to ensure a tight fit and avoid leaks.
c)
Please note that the following part (Item 4a)
must be connected to the male end of the
dual check valve (Item 4), otherwise water
flow will be severely restricted.
Take the ½”
female to ½” male chrome hex adaptor (item
4a) and screw the female end to the dual
check valve (item4). Apply plumbing tape to
the ½” male end of the chrome hex adaptor
(item 4a).
6. Attach Flex Hose (item 5)
Connect the ½” female end of the Pex Hose
(item 5) - to the ½” male end of the chrome hex
adaptor (item 4a) as shown in diagram.
7. Attach Filtered Water to Cold Water Line of
Kitchen Tap
Take the braided flex hose that is attached to
the kitchen tap. Having applied plumbers tape
to the ½” male hex nipple (item 6) – screw the
½” female end of the braided flex hose onto the
nipple (outlet side of filter head).
8. For Horizontal Installations – Install Support
Bracket (item 7)
Where the system is installed horizontally the
unit requires support at the base of the filter
cartridge with the Stabilizing Bracket (item 7).
Locate the bracket (item 7) in a position that
allows three important functions;
a) Firstly, the bracket needs to be located so
that the filter cartridge can be removed when
it is replaced. Suggested location is at the
base of the filter cartridge.
b) The bracket must be level with the filter head
– so that the filter cartridge sits in a level
horizontal position.
c) Finally, the bracket needs to be screwed into
the cabinet using the two remaining mounting
screws (item 3) and set in a manner whereby
the bottom of the bracket supports
the water filled filter cartridge horizontally.
9. Install Filter Cartridge (item 2)
a) Hold filter head (item 1) firmly with one hand.
b) Align cartridge lug with label on filter head.
c) Insert filter cartridge (item 2) and push into
filter head assembly (item 1).
d) Turn it to the right (about ¼ turn) until it stops.
10.
Flush the Filter Cartridge
a) Turn mains water supply back on at mini
cistern tap.
b) At this stage check for leaks and fix if
necessary
c) Turn kitchen tap on and flush the filter
cartridge for at least 3 minutes. Collect
water in container and use for garden etc.
NOTE – Flushing the filter cartridge is important
to remove air from the system and any loose
carbon. At first the water may appear cloudy
due to compressed trapped air in the filter and
hoses. However the cloudiness will disappear
over time and with use.
11. Installing the Filter Monitor Alarm (item 8)
The filter monitor alarm (item 8) is supplied to
assist you with knowing when it is time to replace
your filter cartridge. Regular annual cartridge
replacement ensures that your filter system is
maintained in accordance with the manufacturers
recommendations.
a) Remove double sided tape and plastic
wrapper from monitor.
b) On the back of the monitor - pull the tab
back.
c) The LED and buzzer will cycle 3 times to
confirm the start.
d) It is programmed to flash and sound again
in
11 months.
e) Remove the two adhesive tapes from the
back of the monitor and locate/mount in a
convenient location under your kitchen sink.
NOTES
1) This installation must comply with all
applicable state and local regulations.
2) Do not use with water that is micro-
biologically unsafe or of an unknown
quality without disinfection before or after
the system.
3) When storing filtered water in a
refrigerator please ensure the container
has an air tight seal / lid.
