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: 30°C (86°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
2.5 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, stop valve, 3/8” push fit connections
and 3/8” polyethylene tubing to allow connection to a 15mm mains pipe to
supply cold filtered water to the pillar tap
Note: If you have a different mains pipe 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 (L), bezel (J) and o-ring (K) 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 (M) and lock
washer (N) over the tap stem and secure the tap into position using the
locking nut (O)
4.4 Screw the 7/16” tap adaptor (H) to the stem on your new pillar tap - do
not over tighten
5. Install the stop valve to your cold water mains supply
– see figure 3
5.1 Turn off your mains water supply
5.2 Install the 15mm to 3/8” stop valve (G) into the 15mm mains supply pipe
to your existing kitchen tap. Choose a suitable location where the mains
supply pipe can be cut to allow easy access to operate the stop valve once
installed.
5.3 The stop valve allows push fit connection of the 15mm copper supply
pipe, ensure that the ends of the copper are cut square and that there is
no damage, dents or burrs. The copper pipe must be fully inserted into the
stop valve connections.
The stop valve is only recommended to connect onto plastic, brass, copper
or mild steel tubing and must only be used fully open or closed to ensure
that the check valve works correctly.
NOTE: Do not use with stainless steel, chrome plated or other hard
metal and polished metal tubes.

9. Prepare the filter for use
9.1 The pillar tap (I) has an indicator light to inform the user when the ceramic
filter requires changing. The light flashes ‘blue’ when the filtered water tap
is operated, if the light flashes ‘red’ the ceramic filter requires changing.
Remove the plastic battery protection strip from the underside of the pillar
tap operating lever to enable the filter replacement indicator function, see
figure 2
9.2 Open the pillar tap and run the water to waste for 10 minutes (or 20 litres)
9.3 Leave to stand for 24 hours to condition the ceramic filter, then run water
to waste for a further 10 minutes. The filter is now ready for use
10. Care and Cleaning
10.1 Use only soapy water and a soft sponge or cloth to clean the filter housing
and pillar tap, avoid the use of:
- Strong oxidising agents such as bleach or Milton solution
- All strongly acidic materials including descalents
- Strongly alkaline materials
10.2 Always ensure that the filter housing and pillar tap are thoroughly rinsed
and dried after cleaning
10.3 If used with hard water or water with very high mineral content it is
necessary to clean and dry the pillar tap after use, build up of calcium and
other minerals could seriously damage the surface of the tap
