INTRODUCTION
Rainfresh Drinking Water System 3 (UCS3) is a premium
performance residential undersink water filter system that provides
clean, safe and better tasting water for your family. It can be used
on any municipal or untreated drinking water supply such as well,
lake or cistern water. The system is designed for installation under
the sink with a separate dedicated faucet (included).
UCS3 uses a unique 4-stage filtering process (fig1). Water first
passes through a high grade activated carbon filter cartridge (CF2)
which reduces chlorine, taste and odour and fine sediment. It also
reduces chemical contaminants such as pesticides (lindane). Next
the water passes through a premium grade activated carbon block cartridge that reduces >95% Lead, Volatile Organic
Compounds (VOCs) and other chemicals. Next the water passes through a self-disinfecting, silver impregnated ceramic
cartridge (1M) which traps and kills >99.99999% harmful bacteria (such as E. coli and other coliform bacteria), traps
>99.95% cysts & protozoa (cryptosporidium & Giardia) and filters particulates as small as 0.3 micron (absolute).
The fourth and final stage is a solid block of high grade activated carbon in the core of the ceramic cartridge (1M) which
acts as a final "polishing" filter for chlorine and unpleasant taste/odour.

SAFETY INSTRUCTIONS
o
This filter system is designed for residential indoor undersink use only. Protect filter from direct sunlight.
o
If water pressure
will at any time exceed the 100 psi maximum, a pressure regulator and water hammer arrestor
must be installed before the filter to prevent
potentially damaging shocks caused by high pressure.
Recommended regulator setting is 75 psi / 5.1 bar/ 517 kPa or less. Not intended for installation in multi-storey
buildings over 4 storeys.
o
Do not subject to freezing temperatures with water inside the unit. If your unit will not be used in winter, or will
be subject to freezing temperatures, drain unit completely (see “Maintenance” section for details).
o
This system is intended for use with cold water only. DO NOT INSTALL ON HOT WATER.
o
Only use Rainfresh filter cartridges with this unit.
No other filter cartridge will function with this system
.
o
Do not lubricate head O-rings with petroleum based lubricants
. Only food-grade silicone (Dow 111 compound)
should be sparingly used.
o
Do not
clean housing with organic solvents such as those found in sprays for cleaning products or insecticides as
these may cause cracking or crazing and lead to failure and leakage.
o
Installation of this unit may involve some water spillage. Keep an ample supply of paper towels or an absorbent
cloth handy.
