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

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

Operating the 3 way Mixer Tap

The 3 way Mixer Tap allows selection of hot/cold and filtered water

Hot/cold water is selected by rotating the right hand mixer lever towards/

away from the user, water flow is controlled by swivelling the lever

outwards from the tap.

Filtered water is selected by operating the left hand filtered water tap lever.

The filtered water tap 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 – see figure 2b

Location of the system and Preparation for

Connecting Pipe work and Fittings

4.1

The filter is supplied with a Mixer 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 mixer 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

4.2

Ensure that there is enough space and access beneath the sink/work

surface to allow installation of your new mixer tap and filter pipe work

Note: When selecting a position for your tap, please ensure that

there is at least 50mm (2") clearance behind the tap to allow the

hot/cold water handle to be opened fully

4.3

Position the filter in an upright position near to the incoming mains cold

water supply and new mixer tap

4.4

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

Install the Mixer Tap.

5.1

Turn off the water supply and unscrew the fittings which connect your hot

and cold water supply to your existing kitchen tap, remove your existing

kitchen tap

5.2

A Ø 36mm hole is required to mount the new mixer tap into the sink/work

surface

Note: When selecting a position for your tap, please ensure that

there is at least 50mm (2") clearance behind the tap to allow the

hot/cold water handle to be opened fully

Fit the flexible supply pipes (X, Y & Z) by screwing the threaded part with

O-ring seals into the underside of the tap body. Ensure that each pipe is

fully inserted and hand tight only – do not over tighten

5.4

Screw the short thread of the threaded fixing studs (T) into the underside

of the tap body. Ensure that each stud is fully inserted and hand tight only

– do not over tighten

Figure 2b

Place the bezel (R) with o-ring seal (S) over the mounting hole with the

5.5

o-ring seal facing downwards. Insert the flexible supply pipes (X, Y & Z)

through the bezel and mounting hole and seat the tap body onto the bezel

5.6

Position the tap so that the filtered water tap lever is on the left hand side

of the tap body and the lever is turned towards the user to operate the tap

5.7

From beneath the sink/work surface place the rubber washer (U) and

metal washer (V) over the threaded fixing studs (T) and secure the tap into

position using the locking nuts (W). Note that the locking nuts are fitted

with the cylindrical portion towards the underside of the sink/work surface
