1. Operating Conditions
1.1 Maximum Working Pressure: 6bar (90psi) - This filter has satisfied the
NSF/ANSI Stds 42 and 53 structural test criteria. However, due to the
potential wide variations of pressures from one installation to another, the
manufacturer advises that if there is any concern that the system would
see pressures above 6 bar then an approved pressure reducing valve set
at 6 bar should be installed upstream of the filter to eliminate any extreme
variations of pressure.
1.2 Maximum Working Temperature: 38°C (100°F)
1.3 Minimum Operating Pressure: 2bar (30psi)*
1.4 Minimum Operating Temperature: 5°C (41°F)
* This will result in a 1L/min flow of filtered water. At 45psi or greater, a
flow rate of 1.5L/min or more will be seen
2. Important
2.1 This filter is intended for installation under the sink away from direct
sunlight
2.2 This filter is not designed for the treatment of hot water and should only be
connected to the cold water supply
2.3 Maximum plastic housing life: 10 years
2.4 Water fittings for use in permanently pressurised systems have a finite life.
It is important that the plastic components in the system are replaced after
10 years usage

PLEASE NOTE: Allowing the unit to freeze will invalidate the
product warranty
3. Location of the system and Preparation for
Connecting Pipe work and Fittings
3.1 The filter is supplied with a Pillar Tap, non-return valve, 3/8” push fit
connections and 3/8” polyethylene tubing to allow connection to a ½”BSP
mains fitting to supply cold filtered water to the pillar tap
Note: If you have a different thread connection you will need to
obtain alternative fittings to adapt your existing pipe work to the
3/8” tube supplied with this system
3.2 Choose a location next to your sink to install your new pillar tap. Ensure
that there is enough space and access beneath the sink/work surface to
allow installation of the tap fixings and filter pipe work
3.3 Position the filter in an upright position near to the incoming mains cold
water supply and the existing kitchen tap and new pillar tap
3.4 Ensure that connecting pipe work will not have any sharp bends. Allow min
100mm (4”) clearance below assembled filter for removal/service of the
cartridge – see figure 1
4. Install the Pillar Tap – see figure 2.
4.1 A Ø 12.5mm hole is required to mount the tap into the sink/work surface
4.2 Assemble the collar
(O)
, bezel
(M)
and o-ring
(N)
over the tap stem and
push into the tap body with the o-ring facing downwards. Insert the tap
stem through the tap mounting hole
4.3 Beneath the sink/work surface, place the plastic washer
(Q)
and lock
washer
(P)
over the tap stem and secure the tap into position using the
locking nut
(R)
4.4 Screw the 7/16” tap adaptor
(K)
to the stem on your new pillar tap - do
not over tighten
5. Install the adaptor to your cold water mains supply
5.1 Turn off the water supply and unscrew the fitting which connects your
mains cold water supply to your existing kitchen tap
If your cold water supply pipe fitting has a ½” BSP Female
connection – see figure 3
5.2 Connect the ½” Male Stem Adaptor
(J)
to the fitting on the mains cold
water supply pipe - do not over tighten
5.3 Connect the ½” Female Adaptor
(I)
to the cold water feed on your existing
kitchen tap - do not over tighten
5.4
Connect the Tee Adaptor
(H)
to the Stem Adaptor
(J)
on the mains cold
water supply pipe
5.5 Measure the length and cut the tubing
(F)
required and use to connect the
Tee Adaptor (H) to the cold water feed on your existing kitchen tap
If your cold water supply pipe fitting has a ½” BSP Male
connection – see figure 4
5.6 Connect the ½” Female Adaptor
(I)
to the fitting on the mains cold water
supply pipe - do not over tighten
5.7 Connect the ½” Male Stem Adaptor
(J)
to the cold water feed on your
existing kitchen tap - do not over tighten
5.8
Connect the Tee Adaptor
(H)
to the Stem Adaptor on the cold water feed
on your existing kitchen tap
5.9 Measure the length and cut the tubing
(F)
required and use to connect the
Tee Adaptor
(H)
to the mains cold water supply pipe
Note: It is important that the tube ends are always cut square
and that the tubes are pushed into the fittings and housing to a
minimum of 18mm (0.75”) to ensure a good seal
