IMPORTANT:Installation must comply with existing State and Local Plumbing codes. Plumbing
The Pressure limiting valve must be installed to ensure the correct operation of the unit and
compliance to the warranty. For your convenience, a Pressure Limiting Valve is included in the
box.
Please note our warranty requires proof of installation by a Licenced Plumber including water
pressure testings and results.
CAUTION:

AS/ NZS3497. This valve must be installed as a standard equipment and as detailed in the
Installation Drawings and Instructions, to provide:
RECOMMENDATION:
water.
HELPFUL HINT:
water.
We recommend you continue to check for leaks for a day after installation.
INCLUDED ACCESSORY: For your convenience the following accessory is included:
Pressure Limiting Valve with dual check valve - limits the pressure to 345kPa (50psi).
For further information please contact Stefani [phone]
To maintain optimum water quality you will need to replace the cartridge at least every 6 months.
Installation Note: A water lter system/tap, like any product, has a limited life and may eventually fail.
Also sometimes failure happens early due to unforeseen circumstances. To avoid possible property
damage, this product should be regularly examined for leakage and/or deterioration and replace when
necessary. A drain pan, plumbed to an appropriate drain or outtted with a leak detector, should be used
in those applications where any leakage could cause property damage, and /or the water supply should
be turned o if no one is home/present.

REPLACING FILTER CARTRIDGES
It is recommended to only use Stefani water lter cartridges with this ltration
system.
This will ensure optimum performance, protection from contaminates and
compliance with the warranty.

1. Turn owater supply to lter system this can be achieved by turning the ball valve on
the main water supply and the storage tank (as shown in the installation drawings)
clockwise until it will not turn any further. Test water supply is oby operating faucet
on sink. If water does not ow from faucet when lever is operated, water is turned o.
2. Unscrew lter housing from system by turning to the left (looking at front view of
system).
3. Remove and discard lters.
4. Clean lter housing with soap and hot water. Do not use any abrasive cleaner, rinse
thoroughly.
5. Remove lter from packaging, place new lter cartridge into lter housing, ensuring
post in bottom of lter housing is located in the centre of lter cartridge.
6. Screw lter housing and tighten.
Helpful hint: After carrying out a lter replacement or any maintenance on lter
systems, we recommend you observe system for possible water leaks for a day after
lter replacement, seals and plumbing to the system may have been disturbed.
Do not over tighten housing as rubber O-ring can be dislodged.
7. Open faucet by pulling lever up. It should toggle into place and stay open.
8. Turn water on. Allow water to run through system for several minutes to expel air
bubbles trapped in the system during the lter cartridge change. Water may appear
milky. These are only tiny air bubbles being expelled from the new lter cartridge.
Flush water until it runs clear.
Note: The ball valve in the system can be turned oin the case of malfunction
of the cut ovalve in the Manifold when replacing the lter cartridge.
LOW /NO MAINTENANCE REQUIRED: The only requirement is changing the lter
cartridges. The life and performance of lter cartridges may vary depending on
volume and quality of the incoming water supply being ltered. Your lter
cartridges may need replacing earlier than 6-8months if you notice a reduced
volume or ow from the lter faucet, or the return of an unpleasant
taste/odour to the ltered water. Please contact Stefani Australasia Pty Ltd on
[phone] or email to [e-mail] if you require any assis-
tance.
