Installation

Note – The filter cannot be used for the treatment of hot water and should only be

connected to the cold water supply.

1.1 Selecting a Position for the Filter

The filter should be fixed inside a unit or to a wall with the screws and bracket

provided, near to the incoming water supply and the user tap. Make sure that the

filter is located so that the connecting pipework does 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 for removal of the filter element

for cleaning or renewal.

An isolation valve and non-return valve should be fitted upstream of the filter (these

are required by law in the UK). The isolation valve may be used to regulate the

maximum flow rate in accordance with the requirements of the filter element used.

Having selected the appropriate fittings, a user tap should be installed in

accordance with the manufacturer's instructions in a convenient position and then

connected to the filter.

1.3 Assembling and Fixing the Filter

Fit the bracket to the filter head using the 4 retaining screws provided and then

having chosen a position for the water filter, mark the position of the bracket fixing

screws onto the wall/unit.

Attach the filter head to the wall/unit with the 2 fixing screws provided.

With the water supply isolated connect the upstream and downstream pipework

to the filter head ensuring that the arrow on the top of the head is showing the

correct direction of flow and that piping/fittings are pushed into the push fittings to

a minimum of 18mm (.75") depth.

Ensure that a sealing washer is fitted onto the filter element threaded mount stem

and screw the filter element into the filter head until washer resistance is felt. Do

not over-tighten.

If there is less than 10 inches clearance below the base of the filter housing, place

the filter body in position over the filter element before screwing the filter element

into the head.

Moisten the O ring on the filter body, check that it is located correctly and then

screw the filter body to the filter head. Hand tighten only.

Conditioning the Ceramic Filter

The filter system should now be ready for pressurisation. With the user tap in the

on position, gradually open the upstream isolation valve until the flow from the tap

has stabilised at the recommended flow rate.

Close the user tap and ensure that the system is watertight.

In order to remove any loose particles resulting from the manufacturing process or

from cleaning the filter element, it is recommended that the first supply of filtered

water should be run to waste for 10 minutes.
