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.
Reverse osmosis filtered water should
not be run through a copper tube.
The pure RO water can leach copper
from the pipe, eventually leading to holes
in the pipe.
DO NOT operate the unit unattended.
NOTE: Filter cartridge life may vary
based on local water conditions and
amount of use.
MOUNTING THE
DEIONIZATION UNIT
The Aquatic Life TI Deionization Unit is
designed to be mounted to a secure surface.
This will allow for the cartridges to easily be
replaced as needed.
The TI module includes a metal bracket with
screw holes for easy hanging.
Use screws designed for the type of
surface that the TI module will hang on.
Once the TI module is hanging on the
screws, tighten the screws to secure the
TI module.
NOTE: If your model includes
rubber plugs on any of the ports,
it is now OK to remove the plug
by simply pulling it out.

INSTALLING THE CARTRIDGES
Each TI cartridge uses a triple gasket seal
to prevent water leaks. The cartridges are
easily installed into the TI module heads by
inserting the cartridge into the head and
twisting to the right.
The TI module heads are equipped with a
valve that automatically turns off the water
supply to each filter cartridge when you
remove the cartridge. To make the removal
of the filter cartridges easier, the heads and
cartridges can be tilted up as shown below.
To install: Twist cartridge to the right
To remove: Twist cartridge to the left
NOTE: Return new cartridge to
down position after installation.
