*Note: The unit has satisfied the NSF std 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 doubt that the system would see
pressures above 100 psig (approx. 6.9 bar) then an approved pressure reducing
valve set at 100 psig (approx. 6.9 bar) should be installed upstream of the filter to
eliminate any extreme variations in pressure.
Water fittings for use in permanently pressurised systems may have a finite life. It
is important that the plastic components in the system are replaced after 10 years
usage.
Extreme cleanliness is important. Wear rubber gloves or wash hands
thoroughly before and after handling the product and take care to ensure
that no contamination of the components occurs during assembly and
cleaning.

1.0 Installation
1.1
Selecting a position for the Filter
The filter should be fixed to a unit or wall with the screws and bracket provided,
near to the incoming water supply and the desired position for the user tap/faucet.
Ensure that the connecting tubing will not have any sharp bends in it. For easy
servicing of the filter there should be at least 4 inches of clearance below the body
of the filter to allow removal of the candle for cleaning or renewal.
1.2
Connecting Pipework and Fittings
The filter head incorporates 3/8" push-fit connections for ease of assembly.
(O/D tubing specification 0.3756"+0.001"/-0.004")
Note: It is assumed for this instruction that flexible tubing is supplied, for an
alternative means of plumbing please contact your Doulton
An isolation valve and non-return valve should be fitted upstream of the filter
(these are required by law in the UK).
1.3
Assembling and Fixing the Filter
Having chosen the position of the water filter, mark the position of the bracket
fixing screws on your wall/unit.
Attach the bracket to the filter cap by using 3 self-tapping screws provided.
Attach the bracket and cap to the wall/unit with the 2 bracket fixing screws
provided
Cut a suitable length of flexible tube, push one end into the inlet push-fit
connection of the filter cap - it should go in to a minimum of 18mm (3/4") ensuring
that the arrow on the cap is showing the correct direction of flow.
The other end of the tube is installed into the mains adapter/valve (see additional
instructions provided).
Note: This filter is not designed for the treatment of hot water and
should only be connected to the cold water supply.
With the remaining length of tube push one end into the outlet push-fit connection
in the filter cap. The other end is installed into the tap/faucet connection (see
additional instructions provided).
Check the O-ring washer is securely in place on the threaded mount of the filter
cartridge and screw the thread into the cap until washer resistance is felt. Do no
over-tighten
When the cartridge seal is made, moisten the O-ring on the filter body and replace
it onto the location grove. The body can now be screwed to the cap. If there is less
than 10" clearance below the base of the filter housing, place the filter body in
position over the cartridge before screwing the filter cartridge into the cap. Hand-
tighten only
