Installation
Installation Note: A water filter 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 replaced when necessary. A drain pan, plumbed to an appropriate drain or
outfitted 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 off if no one is present.
INSTALLATION MUST BE COMPLETED BY A LICENCED PLUMBER. FAULTY OPERATION
DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.
Installation
1. Place the RO system in a cool & dry location, allowing 200mm below the unit for lter
changeouts.
2. Mount the unit to the wall using the pre-cut holes in the bracket.
3. Isolate the water supply and release the pressure.
4. Connect the water supply to the ⅜” Inlet (LEFT side) and the ⅜” Outlet (RIGHT side) to the
machine.
5. Connect the ¼ BLACK tubing to the Drain, DO NOT connect this to the inlet of the machine.
An inline ow restrictor is pre-installed for water supply under 500 mg/L [ppm] TDS. If
your water is above 500 mg/L [ppm] TDS you will need to change the ow restrictor to the
supplied ow restrictor marked “2000”.

OUT button to view the Outlet TDS level.
11. Rotate the Needle Valve in a counterclockwise motion until the desired TDS level has been
reached.
