Twist-In 75 GPD 4-Stage RO/DI Unit
Installation, Operation & Maintenance Guide
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 service.
OVERVIEW
Reverse osmosis is the process of removing
contaminants from tap water using a special
semipermeable 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 wastewater
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.

WARNING:
carefully before proceeding with
installation. Your failure to follow
any attached instructions and
operating parameters may lead
to the product's failure.
OPERATING GUIDELINES
DO NOT use with water that is micro-
biologically unsafe or of unknown quality
without adequate disinfection before or
after the unit.
The maximum incoming water pressure
for the unit is 80 PSI.
If the pressure is more than 80 PSI, a pressure
regulator is required. If the water pressure is
less than 40 PSI, a booster pump is needed.
Water hardness should not exceed 10
grains per gallon or 170 parts per million.
Operating above this may shorten the
membrane life.
Reverse osmosis filtered water should
not be run through a copper tube.
RO water can leach copper from the pipe,
eventually leading to holes in the pipe.
DO NOT operate the unit unattended.
