Model: 540371
Twist-In 100 GPD 4-Stage RO/DI Unit
Installation, Operation & Maintenance Guide
WARNING: Please read carefully before proceeding with
installation. Your failure to follow any attached instructions and
operating parameters may lead to the product's failure.
Thank you for purchasing an Aquatic Life Twist-In (TI) Reverse Osmosis & Deionization Water Unit.
When maintained properly, this unit will provide you with years of high quality filtered water.
OVERVIEW
Reverse Osmosis is the process of removing contaminants
from tap water using a special semi-permeable membrane.
By applying water pressure across the membrane,
contaminants are concentrated on one side of the
membrane and filtered water on the other side of the
membrane. This is why Reverse Osmosis units have a
waste water line as well as a filtered line.
In addition to the membrane, water is filtered prior to the
membrane with a sediment cartridge to remove larger
particulates, and a carbon block to remove chlorine and
other materials.
After water is filtered by the membrane, it passes through
a color-changing resin cartridge where additional Total
Dissolved Solids (TDS) are removed from the water.
The cartridges and membrane on your unit are designed
for easy installation and replacement. Each cartridge
connects to the filter housing by simply inserting and
twisting. It is important the cartridges be installed in
the correct order to effectively filter the water.
STAGE 1 –
S
SEDIMENT FILTER
Recommended change 6 months
The first stage of your RO/DI unit is a five micron Sediment
Filter that traps sediment and other particulate matter like
dirt, silt and rust which will affect the taste
and appearance of your water.
STAGE 2 –
C
CARBON BLOCK FILTER
Recommended change 6 months
The second stage of your RO/DI unit is a Carbon Block
Filter. The activated carbon in the filter reduces chlorine
and conditions the water prior to the RO Membrane.
STAGE 3 –
RO
RO MEMBRANE
Recommended change 2 Years
The RO Membrane reduces impurities known as Total
Dissolved Solids (TDS) from the water down to 1/10,000
of a micron, reducing arsenic, lead, parasitic cysts, copper
and more. Because the process of filtering the high quality
water takes time, it is common to use a storage tank to
collect filtered water, making it available on demand.
STAGE 4 –
DI
COLOR CHANGING RESIN (DEIONIZATION)
Replace filter when resin changes color
After the water is filtered by the membrane, there is usually
a small amount of Total Dissolved Solids (TDS) left in the
water. In certain non-drinking water applications, it is
important to remove the remaining TDS from the water.
This is accomplished by filtering the water through a resin
that is charged with Cation and Anion resins (H+ and OH-).
As the resin absorbs the TDS, it will change color. When all
resin has changed color, it is time to replace the DI filter.
NOTE: Filter Cartridges and Membrane life may vary
based on local water conditions and amount of use.
