Thank you for purchasing an Aquatic Life Deionization System. When properly maintained, this unit
will provide you with years of high quality, low TDS filtered water. Contact us with any questions or if
you are missing or need replacement parts at 888-548-3480, or customersupport@aquatic life.com
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 and possible property damage.
OVERVIEW
Water quality is often measured by the amount of Total Dissolved Solids (TDS) in the water. After water
is filtered by an RO Membrane (not included), there is usually a small amount of 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 the entire resin has changed
color, it is time to replace the DI Cartridge. NOTE: Filter Cartridges and Membrane life may vary based
on local water conditions and amount of use.

OPERATING GUIDELINES
DO NOT use with water that is microbiologically 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.
Reverse Osmosis filtered water should not be run through a copper tube. The pure RO/DI water can
leach copper from the pipe, eventually leading to holes in the pipe.
DO NOT operate the unit unattended.

Tools & Materials Recommended for Installation
Straight Edge Razor Blade
Phillips Screwdriver
INSTALLING THE PRESS FITTINGS
The Unit includes both straight and 90° elbow ¼” fittings that will thread into the sides of the Unit
housing and allow for easy connection of the tubing.
Step 1 –Select either the straight or 90° elbow to connect to the Unit housing and wrap plumbers tape
around the threaded end of the fitting at least three times.
Step 2 –Thread the fitting into the Unit housing. DO NOT OVERTIGHTEN Repeat for the other side of the
Unit housing.
MOUNTING THE DEIONIZATION UNIT
The Aquatic Life Deionization Unit is designed to be mounted to a secure surface. This will allow for the
cartridges to easily be replaced as needed. A metal bracket with screw holes is provided. Use screws and
hardware designed for the type of surface that the DI Unit will hang on. Leave the screws extending
about 1/8” from the surface and then hang the metal bracket on the screws.

HOW TO USE THE BUDDIE FIT ™ PRESS FITTINGS

INSTALLING THE CARTRIDGES
Step 1 -Use the Canister Wrench in a clock-wise direction to gain access to the Deionization Cartridges.
For proper operation, the water must flow into the right canister first and water flows out of the left
canister.
NOTE: Use care to center the cartridges in the middle of each Canister prior to re-attaching the
Canisters.
INSTALLING THE TDS METER (MODELS 540502 & 540503 ONLY)
A TDS Meter is included with the DI Filtration Unit. Refer to the Instructions included with the Meter for
operation. The TDS Meter is capable of measuring the TDS from two different points in your filtration
system. We recommend you place one probe prior to the water entering the DI Filtration Unit and the
other probe where the water exits the DI Filtration Unit –photos on next page show how to connect.
Measure Point 1
Most RO Units remove 95 -98% of the TDS from your water. The TDS Meter will allow you to
monitor the TDS of Membrane filtered water so you know when it’s time to replace your
Membrane.
Measure Point 2
Connecting one of the TDS Meter probes to the water line exiting the DI Filtration Unit will allow
you to monitor if the DI Resin is completely exhausted. When you see the TDS rise above zero,
you will know it’s time to replace the resin in the cartridge.
