7 Retrofit Kit For Undersink System Upgrade
Installation Procedure
Installation Procedure to An Existing Filter Tap System
Where line pressure exceeds 500 kPa, an approved pressure limiting device must be installed to
comply with Australian & New Zealand Plumbing Standards. (Ref. AS/NZS 3500.1-2003, Clause
3.3.4). Install the pressure limiting valve prior to the cold water line inlet on the filter system.
1. Isolate the water supply and release the water pressure by operating the faucet lever.
Disconnect the existing tube connections on the existing system (inlet and outlet).
Note: Place a container underneath the system to catch any water spillage.
2. Install the head assembly by positioning it in the desired location, marking the position
of fixing holes and fixing with mounting screws (can be mounted horizontally or
vertically). Allow room for the connecting hoses and for removing the cartridge (70
mm) as per the installation diagram.
Note: The arrow on the head indicates the direction of the water flow.
Note: Knocking the cartridge can cause the cartridge to come out of the locking
position. To limit the likelihood of this occurring it is best not to store items too close to
the system to avoid accidental dislodgement of the cartridge.
3. Install filter cartridge to the head assembly. Please note the arrow on the cartridge
label indicates Undo and Install directions.
Warning: Ensuring the cartridge is in the correct lock position is critical prior to
operating the system. Not being seated in the correct position can cause the locking
tabs to shear and damage the head and/or water leakage. See Fig 4 for the correct
position.
4. Push one of the reducers into the outlet and one into the inlet of the cartridge head,
ensuring it is pushed in all the way in (see Fig. 3 ).
6. Connect the tube from the cold water line to the inlet side reducer and the tube
connected to the filter tap to the outlet side reducer (see Fig 2).
7. Make sure all fittings are tight and the tubes are 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 aer a short period.
