may be used on disinfected waters that may contain
filterable cysts.
CAUTION: This filter must be protected from freezing, which can cause
cracking of the filter and water leakage.
CAUTION: Because of the product’s limited service life and to prevent
costly repairs or possible water damage, we strongly
recommend that the head of the filter be replaced every
ten years. If the head of your filter has been in use for
longer than this period, it should be replaced immediately
Date the top of any new head to indicate the next
recommended replacement date.

1. Selecting the Tap Location
NOTE: The drinking water tap should be positioned with function, convenience and
appearance in mind. An adequate flat area is required to allow tap base to rest
securely whether fitted directly to your sink or an adjacent worktop.
1. Preparing to Fit the Tap
WARNING: Wear safety glasses to prevent eye injury.
Sink Location
The following instructions apply to porcelain-coated cast iron and stainless steel sinks only.
(A) Line bottom of sink with newspaper to prevent metal shavings, parts, or tools from
falling down the drain and damaging sink or disposal unit if fitted.
(B) If sink is porcelain-coated, place masking tape over area to be drilled to prevent
excess chipping of the enamel coating. Use a cone-shape grinding wheel to grind
away a 3/4-inch diameter circle of porcelain before drilling.
(C) Mark hole with a centre punch. Use a 6mm drill bit for a pilot hole, then using a
12mm diameter bit, drill a hole completely through the sink or worktop. Smooth
rough edges with a round or half round file.
Base of Tap
Work Surface
Black Rubber Washer
Worktop Location
(D) The tap should be positioned on a work surface adjacent to a sink where
the spout can easily discharge water into the basin.
White Plastic
Locating Washer
Lock Nut
Star Washer
(E) Using a pencil, mark the work surface to indicate the centre of the tap.
(F) Drill a 1/2” hole where marked on the work surface.
Tube Insert
(G) Smooth any rough edges with a round or half round file.
Compression Nut
Blue Flexible Tube
2. Installing the Quarter Turn Tap
(A) Insert the black rubber washer into the base of the tap.
(B) Insert the threaded section of the tap body into the 1/2” hole.
Piercing Screw
(C)Assemble the washers and lock nut on the threaded section as over.
(D) Tighten the lock nut to prevent the tap moving. Do not over tighten.
(E) Ensure compression nut, ferrule and tube insert are positioned on the blue flexible
tube shown over.
Cold Mains
Red Flexible
(F) Insert the open end of the blue flexible tube assembly into the base of the threaded
section of the tap.
(G)Tighten the compression nut to ensure a watertight seal. Do not over tighten.
3. Installing the Saddle Valve
Before carrying out any installation TURN OFF THE WATER SUPPLY AT
lace the saddle clamp on to the cold mains supply pipe to the kitchen sink. Make
sure that the SADDLE A is in place as shown in the diagram.
•Tighten the locking screw C to clamp the pipe securely.
•Turn the piercing screw B clockwise and fully home to puncture the pipe,
leave in this position.
4.Mounting the Filter System
(A) Taking note of the length of connecting tube available select a suitable position for
the cartridge (normally on the side of the cupboard underneath the sink)
(B) Using the bracket as a guide mark the position of the fixing holes with a pencil.
(C)Drill a small pilot hole for the screw.
(D) Fix the bracket supplied to the side of the cupboard using suitable screw (wood
screw supplied an alternative fixing may be required)
(F) T he cartridge can be clipped into the bracket or removed at anytime to help with
remaining installation.
CAUTION: Do not attempt to drill through an
all porcelain sink. If your sink is porcelain,
please consult a professional plumber
about installation.
5.Final assembly
A) Using a sharp hobby knife or similar to cut the flexible red tube from the self cutting
tap to a length suitable for it to reach the inlet side of the filter cartridge. Remember
to allow a sufficient length, so that it can be routed without kinks and be kept clear of
any sharp edges or obstacles.
(B) With the tube cut ‘squarely’ and to the right length, ensure the end is clean before
firmly pushing it into the push fit connector on the inlet side of the filter cartridge,
pull back slightly to affect a water tight seal.
(C)Repeat process for the touch flow tap, attaching tube to the outlet side of the cartridge.
(D) Turn on water supply and check all connection for leaks.
(E) Turn on the quarter turn tap to remove any airlocks. Run water for several minutes
until water runs clear to flush and prime cartridge.
NOTE: for optimum performance, flow rate should not exceed 2 lm.
6.Filter Cartridge Replacement
NOTE: It is recommended that the cartridge be replaced every six months, or when you
notice a change in taste, odour, or flow of the water being filtered.
A) Turn off the water supply to the filter and dispense water from drinking water tap
until water flow stops to relieve pressure.
(B) Place a small bowl and towel under the filter to catch any water drips.
(C)If necessary remove filter cartridge from the bracket to improve your access.
(D) Now disconnect the red and blue tube from the filter cartridge one at a time by
placing your finger and thumb either side of the tube where it enters the filter
cartridge and pushing the small white collar toward the filter body this will release
the tube. Hold the collar in this position and gently pull the tube out of the cartridge.
(E) Remove and dispose of the cartridge, recycling where facilities exist.
(F) Fit the new cartridge by simply pushing the end of the red tube into the push fit
connector on the inlet side of the filter cartridge, pull back slightly to affect a water
tight seal.
(G) Repeat process for the blue tube, attaching it to the outlet side of the cartridge.
(H) Turn on water and check for leaks.
(I) Flush water through drinking water tap for up to 5 minutes to remove air, and any
excess filter media.
