Installation Procedure
Installation Procedure
1. Select suitable location that is close to the existing tap. Remember to allow access
room for changing filter and a suitable place where water spillage will not cause
damage. Location should not be in direct sunlight.
2. Isolate water supply and release water pressure by operating faucet lever. Disconnect
existing braided hose connections from the cold water line.
3. Attach non-return valve to water supply with thread seal tape. Then detach the 1/2"
DR Brass adaptor from the non-return valve, apply thread seal tape as necessary and
reconnect to the non-return valve.
4. Install filter cartridge to the head assembly (see Fig. 1). Please note the arrow on the
cartridge label indicates Undo and Install directions.
5. Push the joint brass/stem adaptors into the inlet and outlet of the cartridge head,
ensuring they are pushed in all the way.
6. Install system assembly by positioning it in the desired location, marking the position
of fixing holes and fixing with mounting screws (PureMix Z Series can be mounted
horizontally and vertically). Allow room for the connecting tubes and for removing the
cartridge (70 mm).
7. Connect the braided hose onto brass adaptor, then connect to the cartridge head
assembly inlet (please note the arrow on the head indicating the direction of the water
flow). A hose extension kit has been provided if necessary, this can be used to extend
the hose either side of the system. Ensure the hose is kink free.
8. Connect the mixer tap's braided hose to the brass adaptor on the head outlet. Make
sure all fittings are tight and braided hose is kink free.
9. Restore the water supply and check for leaks. If leaking occurs then undo cartridge and
check the cartridge is seated properly.
10. Run the system for at least 10 minutes (turn on mixer tap to run cold water) to remove
carbon fines. Water may appear milky, but this is normal and is only tiny air bubbles
that will clear after a short period.
