Puro Range Water Purification System Operation Manual
Introduction

Introduction
The Puro water purification system produces Type 3 water (1 to 40 µS) at a rate of 10, 20, 50 or 80 litres
per hour. Type 3 water is stored in an external storage tank where it can be dispensed when required, or be
connected to a distribution system.
All components are assembled around a reservoir chassis and are protected by a plastic housing designed
for bench or wall-mounting. The plastic covers can be removed for access to replaceable components.
All recorded data, warning messages, and dispensing information can be viewed from the controller dis-
play.

Purification Process
In normal operation, feed water enters the system via the inlet solenoid valve (
V3
), engaging the
Reverse
Osmosis Pump
(
P1
). The conductivity of the feed water is measured by the feed water
conductivity
sensor
(
Q1
) before it reaches the pump.
