Technical Overview  

I. Important Notes 

For correct operation of this appliance, it is essential to observe the manufacturer’s instructions. 

Installation must be carried out by a qualified plumber or authorised technician to comply with Australian 
Plumbing Codes. This RO system is certified to WaterMark Standards AS/NZS 3497 Under the Certificate 
number 23247. WaterMark certification is the level of certification required by law for a licensed plumber in 
Australia to install a water filter system. 

You will find most answers to your queries can be found in this instruction manual – please 
thoroughly read through this manual from front to back including the troubleshooting page before

 

contacting customer support. 

II. Before You Purchase/Open 

The system requires specific working conditions to be met before installation. If these conditions are not 
met, the system may not be suitable for the application and may not function as specified.

IV. Before You Begin Installation 

All components that come pre-assembled will need to be thoroughly checked before installation. Due to 
transit, fittings and other components may be loosened or unseated – ensure fittings, tubing and filters are 
inspected before continuing. 

V. What is Reverse Osmosis 

Reverse osmosis is a process that uses a semi permeable, spiral wound membrane to separate and 
remove dissolved solids, organics, pyrogens, colloids and bacteria from water. The Feed water is delivered 
under pressure at 50psi or above through the permeator where the water permeates the minute pores of 
the membrane and is split into purified water which is delivered to the tap, and concentrate (reject) water 
which is sent to waste. Reverse Osmosis is capable of removing 85 – 99.99% of a large range of solids 
from water (depending on the solid) along with Organics and Bacteria.
